Submerged Settlements And Roman Road Discovered Under Venice Waters
Submerged Settlements And Roman Road Discovered Under Venice Waters
An underwater sonar mapping project by archaeologists in Italy has determined that the bottom of the Venetian Lagoon was once dry land. The team of researchers have confirmed that an ancient Roman road and settlement once thrived in the area some 500 years before Venice was founded in the 5th century.
In the 1980s, surveys of the Treporti Channel in the northern part of Venice's outer lagoon identified what ‘looked like’ a submerged Roman roadwith structures aligned along its course. Recent archaeological dives revealed stones with a smooth upper face and ovoid undersides that were similar to “Roman basoli.” Now, it has been confirmed that an ancient Roman road was indeed submerged in the Venice Lagoon, and it was lined with “extensive settlements.”

Professor Fantina Madricardo is a geophysicist with the Institute of Marine Science (ISMAR) in Venice, and last week she published her new study in the journal Scientific Reports about the recent sonar explorations of lagoon islands and waterways. Hoards of artifacts were discovered suggesting human occupation and even evidence of a structure that is suspected to be an ancient harbor, or dock.
These new investigations of the suspected ancient route were delayed by extensive industrial developments around the lagoon. But now, “12 archaeological structures” have been identified on a northeasterly alignment extending “1,140 meters” in an area of the lagoon known as the Treporti Channel,” according to the study.
The new discoveries at the bottom of the Treporti channel determine the structure was indeed a Roman road and the foundations clinging to its sides measure 2.7 meters (9 ft) tall by 52.7 meters (173 ft) long. Four additional structures measured four meters (13 ft) tall and 134.8 meters (442 ft) long which are thought to represent a harbor, or dock.

The zoom-in pictures show the detail of some of the archaeological structures: the sites 3, 8-9 and 10 (bottom-right) and the structure a (top-left), with the profiles I-II and III-IV, that could possibly be possibly part of a harbour structure. The lower part of the picture represents the bathymetric profile extracted along all identified structures (white dashed line).
Professor Madricardo told Live Science that the Venice lagoon formed after the main sea-level rose at the end of the last Ice Age . She said that since Roman times, about 2,000 years ago, “the sea level there rose [up to] two and a half meters [8 feet].” This means what was once dry land is now underwater. It is thought the Roman road ran along the top of a sandy ridge where the outermost islands of the lagoon are located today. Water would have lapped both sides of the road with the eastern side facing the sea and the western side being an enclosed inland waterway, the researchers said in the study.

The position of the TC road corresponds exactly to the position of the archaeological structures mapped.
Having waited since the 1980s, what these new archaeological confirmations mean is that a permanent settlement was established in the Treporti Channel during the Roman era . From this, the authors of the new study suggest the road “may have been linked to a wider network of Roman roads in the Italian Veneto Region.” The team speculate that the settlement might even have been a staging post for sailors and traders heading to and from the city of Chioggia in the Northern Venice Lagoon and the Roman trading center of Altinum in the north.
Now that the presence of the Roman road has been confirmed by sonar mapping and underwater divers, and that the structures have been measured, the next part of this underwater quest is to date when the road was built. Moreover, it is yet to be determined how long it took the skilled Roman road builders to create the route. And it is not yet understood how long the trade route was functional before it was reclaimed by the rising sea. Professor Madricardo says the lagoon sediment cores have been damaged over the last two centuries, but she is hopeful the floor of the lagoon can be radiocarbon dated , which might answer these big outstanding questions.

Did Japanese Population Originate with this Minatogawa Man?
Did Japanese Population Originate with this Minatogawa Man?
A new scientific report published in Nature has concluded that the modern Japanese descended from the Minatogawa people of the Paleolithic era. This is based on a DNA study of a 20,000-year-old human, codenamed Minatogawa 1, who was discovered in a limestone quarry in the Japanese Okinawa Prefecture back in 1970.

The Origins of Modern Human Japanese Population
Paleoanthropologists have long assumed that modern man ( Homo sapiens ) first migrated east out of Africa and into modern-day China about 50,000 BC. The popular belief is that the first humans on the Japanese Archipelago migrated from somewhere in southeast Asia. According to human migration models and archaeological evidence, people first reached Japan in the late Pleistocene, around 40,000 or 30,000 years ago, at a time when the archipelago was connected to the Asian continent.
The frequently told story of human history in Japan claims that the modern-day Japanese descended from two different groups of migrants. These were the historic ancestors of the Jomon people, hunter-gatherers who existed between 14,500 BC and 1,000 BC. Later they were followed by a second wave of farming human migrants from Northeast Asia known as the Yayoi who existed between 1,000 BC and 250 AD. Both cultures have been identified due to their distinctive pottery styles.

In the late 1960s, amateur archaeologist Seiho Oyama purchased a series of stone blocks in which he observed fossilized bone fragments within. This unexpected discovery led to his near obsession with the Minatogawa quarry in the Okinawa Prefecture, on the Japanese Ryukyu Islands, from where they had been sourced. In 1968 Oyama reported the discovery of human remains to a Tokyo University professor who then proceeded to excavate the site up until 1974.
Digs at the site took place in a 1-meter-wide (3.28 ft) exposed fissure at the quarry. Archaeologists unearthed bone fragments belonging to between 5 and 9 individual skeletons, which they named the Minatogawa people. The Tokyo University professor who led the excavations, Hisashi Suzuki, argued that these Paleolithic individuals had been killed by arrows or spears and were then cannibalized.
The males were about 1.55 meters tall (5 ft) while the women were about 1.4 meters (4.6 ft) tall. “Narrow-shouldered, they had a sturdy lower-body skeletal build, which experts believe made them suited to running on barren land,” explains Archaeology News Network . Minatogawa 1 is the name given to a complete skeleton found at the site, a replica of which is now on display at the Tokyo University Anthropology Museum.
This discovery was very exciting for Japanese archaeology, due to the lack of skeletal remains and DNA unearthed to date on the islands. This is caused by the acidic soil composed of volcanic ash which creates “an environment which is detrimental to the preservation of ancient biomolecules,” explains the report in Nature. The 20,000-year-old remains discovered at the Okinawa quarry “are amongst the few Paleolithic humans whose remains have so far been discovered in Japan,” explains Archaeology News Network .

Science Uncovers New Links to Explain the Origins of Japanese Population
Nevertheless, after the excitement subsided researchers were unable to uncover the link between these Minatogawa peoples and the story of human history in Japan as evidenced in the rest of the archaeological record. Were these Minatogawa peoples the ancestors for the Jomon? Had the Minatogawa died out? Or had they simply emigrated somewhere else at some point in ancient history?
Due to a lack of evidence to prove any direct connection, Archaeology News Network highlights that “the issue had remained moot, not least because the facial skeleton of the Minatogawa people bore little resemblance to Jomon people.” That is until a group of researchers from a selection of institutions, including the Graduate University for Advanced Studies and Toho University, came together to look at mitochondrial DNA.
Minatogawa 1, the male Paleolithic human found at the quarry, became the focus of the study after the team managed to extract a complete mitogenome sequence. Their hope was to trace the human origins of Japanese population further back than the Jomon. To understand why this was an important breakthrough, “Mitochondrial DNA is passed down from mothers to their children and contains region-specific vestiges due to mutations, which allows origins of populations to be traced,” highlights Archaeology News Network .
Through analysis of Minatogawa 1’s DNA, the team were able to identify a component common to the Jomon, the Yayoi and modern Japanese humans. While an analysis of about 2,000 modern-day members of the Japanese population did not find any direct descendants, that doesn’t rule out the possibility that Minatogawa direct ancestors will not be discovered in future studies.
In a nutshell, this means that the “modern Japanese likely have distant ancestral ties with Minatogawa people.” Nevertheless, to truly decipher the human history of Japanese populations, archaeology will need to keep digging to find more Paleolithic bones and do more tests on existing human remains. The lead author of the study, Jun Gojobori, stressed that they “hope to study the bones of more Paleolithic people to better understand the origins of the Japanese .”

The annals of UFO lore are peppered with accounts of alien encounters and abductions, these mysterious entities coming for us for inscrutable reasons we may never understand. Some such cases really serve to bring on the weird, with plenty of clues and details that cloak them in a thick layer of oddness and high strangeness, leaving us to wonder just what is going on. One such surreal account played out in a rural area of the U.S. state of Indiana back in 1983, and it has gone on to become a classic example of just how truly bizarre such encounters can be.
It was a hot summer night, on June 30, 1983, and Debbie Jordan-Kauble was going about her usual routines on what had until then been a very ordinary, mundane evening. At the time she was living in a rural area near a place called Copley Woods, outside of Indianapolis, Indiana, along with her two young sons and parents and on this evening her father was off at his second shift at an automobile factory. That night Debbie, her mother, and two sons ordered take-out fried chicken, and it couldn’t have been more normal, but as she washed the dishes and the grease off her hands things would begin to get weird, spiraling into a harrowing experience that would change her life forever. She would say of what happened:
I was washing the grease off my hands before I left to go to the neighbors house to cut some more patterns out. She lived one block over and one road behind us so I wouldn’t be far in case Mom needed help getting the boys to settle down. As I stood at the kitchen sink and looked aimlessly out the window, I noticed an odd light coming out of the swimming pool pump house. First of all, I knew the door SHOULD be closed because I remembered wrestling with the rusty slide lock. I had been out there just a few hours earlier, putting some more chlorine tabs in the pool floater. It was getting dark out so the strange light really caught my eye. It was not like the incandescent bulb that was in there. It looked more like florescent, white light. And it was very bright. I pointed this out to my mother and asked her if she wanted me to stay home. She thought it was odd but told me not to worry about it. She would lock the doors and if she needed me she would call me. In the five minutes it took me to get in my car and make a quick detour to the turnabout in back of the house, to check on the light before I left, the light was gone. And the door to the pump house was closed. But the pedestrian door to the side garage attached to the house was now open. I do not know why I didn’t stop then and go back inside. I should have but I didn’t. I headed on to our neighbors’ house.
Debbie reached her neighbor’s house without incident and called her mother to tell her she had arrived safely. At this point her mother was calm and sounded normal, but shortly after this, practically right after hanging up, there was a phone call from her mother, who now sounded frightened and urgently implored her to come back home right away. It would only later turn out that Debbie’s mother had seen a “basketball-sized ball of light” hovering around in the back yard, but at the time it was not clear why she was so panicked and scared, so insistently begging Debbie to come home immediately. Debbie then excused herself, apologizing to the neighbor and driving the short distance back home, where she found her mother cowering within and frantically looking through the window outside. Debbie says of what happened next:
Once I arrived, I pulled around to the back of the house again. This time I stopped at the sun room outside access door and found Mom standing there waiting for me. As I walked in, I went for the shotgun Daddy had behind the trash compactor. Mom made a comment about the gun not being loaded and I said to her that whoever was out there didn’t know that and I could always beat the crap out of them with it. I have to say, at this point, that I do not know what came over me. I am no fool and at that time in my life, I was the biggest chicken in the world. If I had know why mom called me back that night, I would have never gone out back. I would have gone in the front door, grabbed my mom and kids and high-tailed it out of there so fast it would make your head spin.
Making the whole situation even eerier and more surreal was that at the time Debbie’s mother not only had no idea why she was in a panic, but she didn’t even remember calling her daughter. At this point, they both thought it was just an intruder, and so Debbie crept outside with the shotgun and approached the pump house, ready to wave her empty gun to frighten any trespassers, but no one was in the pump house, nor was there any sign of an intruder anywhere. The only thing out of place was her dog cowering under a truck and growling uncontrollably. As she did her search of the yard, outbuildings, and garage, she was suddenly aware of a growing, burning sensation throughout her body, which she would later equate to being splashed with acid, and whish grew in intensity until she had the sudden, undeniable urge to get out of there immediately, that her life was in danger. She would say of what happened next:
I suddenly felt as if I was on fire. All the skin on my body started burning. It felt like I was covered with acid. And I thought, “I’ve gotta get out of here RIGHT NOW!” I turned to run out the pedestrian door and that is when I was hit in the chest by something VERY bright and electrifying. I have never been hit by lightning. But if I could imagine what it would feel like, I would say it was like this. It felt as if I had first been punched by a huge, electric fist, right in the gut. The burning, electrical feeling slowly moved down my legs to my feet, out my arms to my fingertips and around my head. Then, I could feel every molecule of my body vibrating. I couldn’t move. And I couldn’t see because the flash was so bright. I know I could not have tolerated more than a few seconds of this but I swear it felt as if this lasted for several minutes. I assume it couldn’t have lasted more than a few seconds. I remember thinking, “I’m DEAD! This is what it feels like to die.” I was shaking and burning and I felt like I was vibrating to my very core. The brightness wore off fast. Then, the vibrating and shaking subsided. But I still couldn’t move. I was able to see bits and pieces. VERY much like having been ‘flashed’ in the eye by a camera flash. I had big blind spots in my vision but I could see some shadow and some movement in the yard in front of my. I can now feel someone pulling on my right shoulder, as if to pull me down a bit. Then, I felt a stabbing, burning sensation in my right ear. And I could hear someone telling me it was unfortunate that I had to feel pain.
After this, she suddenly and inexplicably found herself outside, with no idea of how she had gotten there, and above her hovered a bight light about the size and shape of a basketball. The light moved up and down, as if scanning her, and then slowly became an oval shape before disappearing. At this moment, Debbie saw another egg-shaped object, around which several humanoid figures could be seen. She explains:
I could see something about the size of the pool pump house. Maybe 8 to 10 feet tall and shaped like an egg. (Not very big as far as UFOs go.) And I could see 6 people in the yard in front of me. They are at various spots in the yard. At the same time, they all seemed to line up and slide to the left, back to this egg shaped thing in front of me. They were smaller than me. Shorter. I thought they looked like children. Bullet shaped children. Bigger in the head and getting narrow at the feet. I couldn’t see much detail, mostly just silhouettes. The rest of this event is still a blur after 20 years. The next thing I remember is hearing someone say. “It’s over.” I suddenly remembered my kids. I thought, “MY KIDS! Oh my God!” And immediately I heard the voice say that my kids were okay. I heard my name being called and I was able to move and I turned and began to walk up the lower porch steps, toward the back kitchen door. With each step I took, the memory of what had just transpired, faded until by the time I reached my mom at the back door, I did not remember anything after I entered the garage. I said to my mom, “Everything’s cool.” And with that, she became animated again. It was as if she was standing there, in a daze, until she heard my voice.
Debbie then went back to the neighbor’s house, where they told her she had been gone for 2 hours, despite the fact that to her only 15 minutes had passed. At this point, she rather oddly felt like going for a swim in the pool, inviting the neighbor and her daughter to join her. As they made their way to the pool, things would get even stranger still, of which Debbie says:
As we walked though the back yard to the swimming pool, my neighbors’ daughter suddenly jumped and yelled, “OUCH.” She said she had stepped on something that made her foot burn, and now her foot was getting numb. By the time we reached the pool, she said her foot felt numb all the way to the knee, but yet she could walk on it. We weren’t in the pool more than 10 or 15 minutes when we all started feeling nauseated, and my eyesight started getting real fuzzy, even though I had not had my head under water. I could see halos around all the outside lights and it was making me dizzy. The girls left and I went to bed. When I woke up the next morning, I could not open my eyes. They were swollen completely shut.
My mother took me to the emergency room. They, in turn, sent me directly to an eye specialist across the street from the ER because they didn’t have anyone on call in ER who was able to treat something like this. This doctor was just across the street and agreed to work me in and see me that morning. He was stunned at the extent of my injury. He kept asking me if I had looked into the arc of a welder’s torch or the sun. I had not. I was given several tubes of cream and some drops to try to heal my eyes. It took SEVERAL weeks for them to fully recover and to this day, my eyes are VERY sensitive to light. And my vision is very far-sighted. Sometimes my eyes will still suddenly burn and turn red, for no apparent reason. Fortunately, this only lasts for a few minutes.
The following week after the incident, they were having a BBQ in their backyard when one of the guests noticed an 8 foot circle with a 20 foot swath of wilted dead grass coming off of it, which for some reason instilled a sense of panic in her. This mark would prove to have some rather strange qualities, of which Debbie has said:
The mark in the yard remained there for nearly five years. Every year snow melted off of it. Animals would not walk on it. There were no bugs in the soil. Even when the grass finally did begin to grow back, the grass in that place was thick, rubbery and kind of a bluish green color. The dandelions that grew around the mark were three times the size of normal ones. The tomato plants my mom had out by the pool, were the size of grapefruits but when you tried to eat them, they were so acidic the skin on your lips would peel off. And the vines were as big around as my forearm. The leaves on a patch of trees behind the mark withered, turned brown and fell off. The power line above the mark shorted out and blew a transformer, melted the wiring and blew out the tubes on the Heathkit HAM radios in the basement of the house, which was right next to the place in the yard.
In addition to the strangeness with that mark in the yard, Debbie would over the years be plagued with inexplicable health issues, nightmares, and other odd incidents, of which she says:
The aftermath of this day was a nightmare for several years. I was ‘shell shocked’. I sat up at night, watching over my children and waiting. Waiting for something. But I didn’t remember what it was I was waiting for. I got sick and stayed sick for over a year. I developed life-threatening allergies, rashes, fevers, swollen glands, diarrhea, bleeding gums and my hair started falling out. My fingernails started growing thin, peeled and had horizontal ridges in them. I developed irregular heartbeats (PAC’s) I started having panic attacks. Almost daily for a long time.
And the dog that was out there with me that night? She had to be put to sleep about 2 and a half months later. All her hair fell out from the head down. She developed black, oozing sores all over her back, her eyes got milky white and she was obviously going deaf. Her teeth all fell out and her gums bled, as well. When we took her to the vet, he was shocked to see how quickly she had deteriorated. She was not that old (about 6 or 7 years) and the way she looked you would have thought she was 20 years old. He advised us to put her down because he felt she was suffering and he could not help her. He figured she was ‘eaten up’ with cancer of some kind. I think of my dog, and the fate she met. In my heart, I believe whatever she encountered that night was directly related to her untimely death. And there is a part of me that STILL worries I will eventually have some kind of cancer related to my experience of that night. There is nothing I can do about it right now, except take good care of myself and hope for the best.
It would also turn out that other people in the area had seen basketball-sized orbs of light flitting about at the time, and it was all weird enough that she reached out to UFO researcher Budd Hopkins, who would conduct a thorough investigation into the incident and write of it in his best-selling 1987 book Intruders – The Incredible Visitation at Copley Woods, after which it would hit the public consciousness and appear in a 1992 CBS mini-series of the same name. In 1993, Debbie’s sister would write a book on it as well, called Abducted! The Story of the Intruders Continues, and it has gone on to be one of the most shocking and intriguing alien encounter reports on record, being investigated by other notable UFO researchers such as Linda Moulton Howe. As for her own thoughts on the whole affair, Debbie herself has remained rather introspective on it all, rather bravely embracing what happened to her and looking at it as a defining moment in her life. She has said of this:
I often wonder what my life would have been like had I not had the experience. I can’t imagine. Truthfully, despite the obvious trauma, I don’t think I would change a thing. I have become a much stronger person. I don’t give credit to the experience or the ‘Intruders’, other than it FORCED ME to be strong, to survive and grow. And I kinda like that about me. That is the story of this day. You know when you can name the date and time of an event, it MUST have made quite an impression on you. June 30th, 1983, made such an impression on me that it actually crushed the old me while molding the new one. Now THAT’S a defining moment.
What was going on here? What forces came for this woman out in that remote location? Was this aliens, interdimensional interlopers, or something else altogether? What has come to be known as the “Copley Woods Encounter” has gone on to become one of the weirder bizarre incidents in UFO lore, and for good reason. It has many elements that are beyond bizarre, full of high strangeness, and while we may never get true answers it stands tall as a singularly weird account.
The Search for Extraterrestrial Intelligence just got two big boosts – a large influx of cash and a famous scientist and ET life proponent to spend it on a new project. The money comes from four rich donors inspired by the words of Harvard astronomy professor Avi Loeb – famous for his theories that the ‘Oumuamua interstellar object was a spaceship – and the new Galileo Projectit is funding will look for SETI with a network of new telescopes and cameras. Is Loeb pushing the SETI envelope to the point where he could end up like the real Galileo – declared a heretic and kept under house arrest for his own unconventional theories and discoveries?
“Science should not reject potential extraterrestrial explanations because of social stigma or cultural preferences that are not conducive to the scientific method of unbiased, empirical inquiry. We now must ‘dare to look through new telescopes’, both literally and figuratively.”
In the press release for the Galileo Project, Avi Loeb tackles the heresy potential head-on – it’s time to “dare to look” at exoplanets and space objects in a new way. He also addresses the type pf researchers that the UFO and ET community is in dire need of.
“After the recent release of the ODNI report on Unidentified Aerial Phenomena (UAP), the scientific community needs the determination to systematically, scientifically and transparently look for potential evidence of extraterrestrial technological equipment. The impact of any discovery of extraterrestrial technology on science, our technology, and on our entire world view, would be enormous.”
The three main objectives of the Galileo Project are to obtain high-resolution images of UAPs (UFOs) using a network of dedicated small-aperture telescopes; search for interstellar objects similar to Oumuamua; and search for extraterrestrial satellites orbiting the Earth. Loeb introduced a sizeable scientific research team at the project announcement. He’s surrounded himself with scientists from various fields and challenged them, other scientists, world leaders and the public to not treat this research the way Galileo’s was treated.
“Moreover, Galileo complained that some of the philosophers who opposed his discoveries had even refused to look through his telescope, e.g., to see the mountains on the Moon, or the four largest moons of Jupiter. Let us not repeat their mistake.”
Look and learn
They refused to look through his telescope. Does this sound like any prevailing practices and philosophies today? The Galileo Project is funding but looking for more financial support from individuals and foundations. In addition to open wallets, what the Galileo Project really needs is open minds. As the real Galileo once said:
“All truths are easy to understand once they are discovered — the point is to discover them.”
Alien abductions come in all shapes and sizes. They range from the odd to the full-on absurd, and everything in between. Yet one assumption that many people might have is that the aliens always get their person, and this is simply not true. Through a series of missteps and and other forces of chance, it would seem that at times these aliens fail in their missions to abduct human beings. While rare, here are some of the more spectacular such accounts.
A very strange account comes to us from the year 1964, from California, in the United States. On September 4, 1964, 28-year-old Donald Shrum and his friends went out bow hunting at Cisco Grove, in Placer County, California, and at some point, he would become separated from his group. Since nightfall was approaching, he decided to sleep in a tree for the night and catch up with his companions the following day, but sleep would not be easy for him on this night. As he drifted in and out of a half-sleep daze and daydreams, his attention was captured by a bright white light zigzagging through the dim darkness of the trees, which he at first took to be a helicopter but would soon prove to be anything but when the mysterious light approached him to begin silently hovering nearby.
Shrum tried to stay out of sight, but it was obvious that it had noticed him, and not only that, three strange beings could be seen on the ground approaching the tree. He would describe two of them as humanoid in general shape, but the other as looking like some sort of outlandish robot, and he was startled when they began shaking the tree with great force, seemingly in an effort to dislodge him and make him drop out. As this was going on, the robot apparently exuded a white mist from its mouth that caused him to fall asleep. When he awoke not long after, the strange creatures were still seemingly trying to get him out of the tree, and he fought back by dropping lit matches on them, which caused them to back off a bit but did not stop them. He then resorted to shooting at them with his bow, noticing that his arrows caused sparks when they bounced off the robot.
As the night wore on, more of the robot-like creatures appeared, and the humanoids began trying to crawl up the tree towards him. Shrum claims that he shot arrows until he ran out, after which he began hurling anything he could find at the strange entities. At one point he was gassed again by that white smoke, but he would snap out of it again to find the creatures still unsuccessfully trying to reach him. He claims that this happened until sunrise, after which they finally gave up and left him alone. Somewhat corroborating his story is that his hunting companions would also later report having seen strange lights in the area at the time.
From 1967 we have an equally harrowing encounter, this time from the vicinity of town of Ririe, Idaho. On November 2, 1967, two Native American boys by the names of Guy Tossie and Will Begay were driving south on Highway 26 when they claim to have seen a small, glowing domed object appear in front of them in a flash of light, about eight feet wide and with humanoid entities of some sort observed within the transparent dome. As the two witnesses looked on in astonishment, their car suddenly came to a stop, the engine dying for no reason, after which the dome of the bizarre craft opened as if on hinges. After this, one of the entities within exited and floated to the ground as if defying gravity, and at this point the witnesses could see that it was only about 3 feet tall, with large black eyes and a hairless head.
This creature then apparently walked right up to their car and let itself in, taking a seat behind the wheel while pushing them out of its way, after which the car began to move forward towards the UFO, which was still hovering there about 5 feet over the road. The car then veered off-road into a field of wheat as the object followed it, the terrified witnesses unable to really comprehend what was going on. When the car rolled to a stop in the field, Tossie made a run for it, heading for the farmhouse of a local farmer named Willard Hammon. The whole way he was followed by the UFO, but it gave up and headed back to the car, where Begay was still with that enigmatic being at the wheel. The creature apparently turned to him to spew forth a barrage of unintelligible sounds “like a bird,” perhaps upset that Tossie had escaped, and then left the car to go floating back up to the waiting craft, which sped off in a zigzag path.
Tossie would later bring the farmer back to his friend, and they would both file a report with the police. Although authorities at first didn’t put much stock in the story, they would find several other witnesses who described seeing strange lights in the sky and their livestock acting bizarrely. Both of the witnesses would insist that these aliens had been trying to abduct them, and that Tossie’s break for freedom had probably saved them from an inscrutable fate. Coming to 1973 we have the od case of Lyndia Morel, who was a masseuse at the Swedish Sauna in Manchester, New Hampshire. On the evening of November 2, she finished a late shift at 2:45 AM and headed towards her home in nearby Goffstown, about eight miles west of Manchester. As she drove, she intermittently saw a strange light in the sky that flashed between yellow, blue, and green colors, but she at first thought it was either an aircraft or a planet. However, it kept blinking and moving about, appearing to get brighter as she drove along. At one point, it appeared right in front of her, so close that she could se that it was a glowing orb covered in hexagonal shapes “like a honeycomb.” At this point, her head was filled with a high-pitched squeal, and she found that she could not remove her hands from her steering wheel, even as her car began moving by itself towards the object. She could see through a window on the side of the object “a smallish humanoid figure standing behind a console of some sort,” which seemed to be trying to send her a telepathic message to calm down and not be afraid. She started to feel a sense of calm come over her, a sleepiness that she couldn’t resist.
It seems that she then suddenly snapped out of a sense of calm that had come over her and managed to regain control of her car, veering off to go speeding off towards a nearby house. She would stop the car and run to the residence to pound on the door even as the UFO hovered nearby as if watching her, that high pitched shriek still assailing her ears. When the residents of the house opened the door and saw the terrified woman, they let her in and called police. It was at this time that the mysterious craft gave up trying to get her and disappeared into the night.
A very spectacular case which may or not have been an attempted abduction, but which still seems worth mentioning, is that of an incident that allegedly went down at the Alsworth Air Force Base in South Dakota in 1977. On November 16 of that year, a security alarm was received at the base, which resulted in an A-1C Jenkins & A-1C Raeke dispatched to investigate the disturbance. When the two arrived at the location of the alarm, they spotted a bright light hovering over the fence line, and Raeke went to investigate. As he climbed a low hill towards the light, he then saw “an individual dressed in a glowing, green metallic uniform and wearing a helmet with visor,” who Raeke commanded to halt and surrender. The trespasser apparently ignored these commands, upon which Raeke aimed his M-16 and once again ordered the strange to stop. This entity then pointed some sort of object at Raeke and a beam of light allegedly struck the M-16 to disintegrate it and severely burn the airman’s hands.
This was an unambiguous sign of aggression, with Raeke taking cover and radioing for backup, and Jenkins soon came to his aid. Jenkins would see two further figures approaching, and he too ordered them to stop, but they came right towards them, prompting him to fire off two rounds from his own weapon. One of the bullets allegedly struck one of the intruders in the chest, while another hit its companion in the helmet, but this did not stop them. One of the figures emitted a beam from an object in its hand, which Jenkins dodged while taking cover. The two intruders then moved off and could be seen getting into a disc-shaped object measuring around 20 feet in diameter, after which they sped off. Raeke would later be found to have suffered second and third degree burns to his hands, as well as levels of radiation found on his person.
A more recent case was given to me personally by a witness who does not want to be named. This individual told me of a surreal experience that started off as just a night drive home from work one evening in an unspecified rural area of California. The story follows some familiar beats with this sort of case, with the car’s radio going haywire and the engine dying. It was at this point he saw a glowing disk around 50 feet in diameter bloom out of the night, and simultaneously felt numbed and paralyzed. He says there was a flash of light, after which he found himself inexplicably outside of his car in the desert night, with two large-headed entities dragging him towards the object. At this point, things would get very odd. He says:
One of these things was doing most of the dragging while the other had some sort of device trained on me. I had the suspicion that this was what was keeping me paralyzed and under control, and then something funny happened. I suddenly felt sensation returning to my limbs, and this creature looked surprised. It then started inspecting its device, and I kid you not, actually smacked its hand against it like you might do with a wonky remote control. I used this moment to kick out at them, knocking one to the ground, and I ran back to my car. The two creatures then seem to have given up. They just looked at me, went into their UFO, and sped off into the night. Although I was terrified at the time, in retrospect it is kind of funny that an alien should have an equipment malfunction like that.
Although the witness in this case provided me with the details very seriously, it is unknown how much veracity it has, and all attempts to get more information have failed. Nevertheless, it seems to belong here, and the thought of an alien having its equipment malfunction is too good to pass up. All of the cases such as these and others like them serve to show that these alien entities might not be as infallible as they are made out to be. Perhaps they are just as lost and at the whims of the fates as any of us, and that is perhaps a comforting thought the next time strange entities come for you in the night.

Did the US Air Force actually build a flying saucer?
Did the US Air Force actually build a flying saucer?
Project 1794 is from the early 50’s, by the United States Air Force and AVRO Aircraft. It used to be secret, but in 2012 the information has been declassified. I was really hyped when I found these two reports online at the National Archives, placed a link on my IFO site so that others could find it, but it didn’t really get picked up. Kind of understand why: on the National Archives these pictures are not that easy to view, and they didn’t color correct the scans. The video I made here is in 4K, so you can read all the pages clearly. (more than 200 pages!)
So yes; a flying saucer! This was serious research, about how to build a real flying saucer, not a UFO of course, but disc shaped aircraft called: Silverbug, Y-2, and the prototype P.V. 704.
They were designed to be VTOL (Vertical Take-Off and Landing) fly supersonic and at extremely high altitudes. Up to Mach 3+ and a 100,000 feet. These specifications are not of a jet fighter. When flying this high and fast, think instead of what has been build in the 60’s: the Lockheed SR-71 “Blackbird”.
The 2 original reports can be found at “the National Archives”.
We've entered an exciting new era in the hunt for aliens.
Jupiter's ocean-harboring moon, Europa, imaged here by NASA's Galileo spacecraft, is widely regarded as one of the solar system's best bets to host alien life.
The desire to know our place in the universe is a core human yearning, and people have pondered the question for thousands of years. Indeed, hundreds of years before the birth of Christ, Greek philosophers such as Anaximander and Epicurus speculated that the cosmos is teeming with planets, many of which may support life.
We couldn't move beyond mere speculation for a very long time, however — until we invented telescopes and developed a proper understanding of the scientific method. Humanity notched both of those milestones centuries ago, and scientists are now going great guns in the search for alien life.
Well, "going great guns" is a bit of an overstatement. But we've made considerable progress, especially in the last decade or so, and some big discoveries may be coming soon. Let's take a brief look at where the hunt for ET has been and where it's headed.
The "cosmic pluralism" theory espoused by Anaximander, Epicurus and their followers didn't take off, unfortunately; it was quashed by the ideas of heavyweights like Plato and Aristotle, who held that Earth is unique.
This latter view aligned nicely with the Christian doctrine that came to dominate Europe throughout the Middle Ages and beyond. So, for a very long time, it was considered strange and was often downright dangerous to hypothesize the existence of life-supporting worlds beyond our own.
The pendulum began swinging back the other way in the 16th century with the dawn of the Copernican Revolution.
"Once it was realized that all the planets go around the sun, it was not hard to imagine that the other planets could be like Earth," then-NASA Chief Historian Steven Dick told writer Michael Schirber back in 2009.
That momentum built as intellectual giants like Johannes Kepler, Galileo Galilei and Isaac Newton continued fleshing out how our solar system works, efforts that reached a near fever pitch during the Enlightenment.
In the 17th century, for example, Czech astronomer Anton Schyrleus considered what creatures on Jupiter might look like. And in the waning years of the 18th century, William Herschel, who discovered both Uranus and the existence of infrared light, postulated that life was widespread throughout the solar system — including on the surface of the sun. (Herschel thought the sun was a giant planet.)
Around this same time, scientists began thinking about how to communicate with our putative cosmic neighbors. One of the pioneers in this nascent field of messaging extraterrestrial intelligence (METI) was the famed German mathematician Carl Friedrich Gauss. In the early 1800s, Gauss proposed carving huge geometric shapes into the Siberian forest to show "lunarians" living on the moon that we're here and know how to do some math.
At the same time, Austrian astronomer Joseph Johann von Littrow suggested digging giant trenches in the Sahara Desert, filling the ditches with water and topping that liquid layer with kerosene. The kerosene would then be lit, producing a fiery signal that would hopefully catch the eye of any aliens keeping tabs on Earth.
These particular ideas were never carried out. But a century later, scientists did start putting some of this alien-hunting talk into action.
One of the first actual life-searching projects took place in August 1924, when a team of scientists led by astronomer David Peck Todd used an airship to loft a radio receiver several miles above the ground — a good spot, it was thought, to listen for messages from creatures on Mars, which was making a particularly close approach to Earth at the time.
But the concerted search for extraterrestrial intelligence (SETI) didn't really kick off until 1960. In that year, Cornell University astronomer Frank Drake used a radio telescope in West Virginia to listen for signals coming from the stars Tau Ceti and Epsilon Eridani. Called Project Ozma, this effort incorporated ideas from a seminal 1959 paper by Giuseppe Cocconi and Philip Morrison.
Scientists have been scanning the heavens for "technosignatures" ever since then. Initially, they focused almost exclusively on radio signals, but flashes of light are in play now as well; these are the targets of increasingly common "optical SETI" efforts.
SETI scientists have to keep an open mind; after all, we don't know what sorts of messages an advanced alien civilization might beam out. So, astronomers in the field generally look for signals that appear weird and artificial, something coming from deep space that isn't produced by any known natural astrophysical phenomenon.
It would also be nice if the signal recurs, so it can be studied repeatedly and in detail. One-offs can remain forever and frustratingly mysterious, as 1977's famous "Wow!" signal shows. In that case, a radio dish operated by The Ohio State University picked up something so intriguing that astronomer Jerry Ehman wrote "Wow!" on the data printout. Researchers scoured that same patch of sky again and again, hoping to get another ping, but they never did.
The SETI hunt, it should be noted, has historically been a shoestring operation; finding enough money to keep the telescopes running has been a consistent problem. The U.S. Congress axed a planned NASA SETI project in 1993, and ever since then, ET hunters have mostly had to turn to the private sector for cash.
Without steady funding, progress was slow for several years. But private money has flowed more freely into the SETI field recently. Most of it comes from one man: tech billionaire Yuri Milner. Passionate about the search for alien life, Milner established an ambitious program in 2015 called Breakthrough Initiatives to seek out extraterrestrials.
Among the projects under the Breakthrough umbrella are the $100 million Breakthrough Listen SETI campaign and the $100 million Breakthrough Starshot, which aims to develop the technology required to send tiny robotic probes to nearby exoplanet systems at about 20% the speed of light.
There's also Breakthrough Message, which aims to both help humanity craft the best possible message to send out into the cosmos and encourage debate and conversation about SETI in general.
And there is considerable debate within the scientific community about SETI.
Some people, including the late physicist Stephen Hawking, have argued that it's unwise to advertise our presence to aliens, whose nature and intent are complete mysteries to us; these creatures may pillage our planet after picking up our ping, after all. But other researchers think any creatures advanced enough to travel to Earth to enslave or eat us would already know we're here anyway.
Breakthrough Message pledges not to actually broadcast any SETI signals until this debate has played itself out. But humanity has already beamed out messages on multiple occasions, most famously in 1974 with the Arecibo message. And those are just the intentional, directed missives; we're leaking radio signals in all directions at all times, providing cosmic bread crumbs for anyone close enough to find them.
Around the same time that SETI was getting off the ground, planetary scientists began getting their first good looks at alien worlds.
In 1964, Mariner 4 flew by Mars, returning the first up-close images of the Red Planet. Those photos revealed a dry, heavily cratered and seemingly desolate world, forcing many scientists to recalibrate previously optimistic notions of Mars' habitability. (Hopes of a life-supporting Mars had been famously stoked around the turn of the 19th century by astronomer Percival Lowell, who claimed that channels on the planet were actually canals built by intelligent creatures.)
But the optimists got some good news in 1969, after Mariner 9 arrived in orbit around Mars, becoming the first spacecraft to circle another planet in the process. This probe spotted river channels and other evidence of past liquid-water activity on the Martian surface. These discoveries helped spur NASA to develop two ambitious life-hunting Mars missions, Viking 1 and 2, which launched a few weeks apart in 1975.
The identical Viking landers each carried four biology experiments, which hunted for signs of microbial life in the red dirt. One of those experiments, called Labeled Release (LR), returned data consistent with evidence of microbial life. Indeed, LR principal investigator Gil Levin argued (and continues to argue today) that the Vikings found evidence of Mars life. However, most scientists who studied the data disagreed with Levin, determining that the data could be explained by abiotic (non-life-based) chemical reactions.
The Viking results taught NASA and astrobiologists some valuable lessons — chiefly, that they didn't know enough about Mars to mount a proper life hunt there. So, the space agency eventually embarked on a long-term "follow the water" exploration strategy, seeking to learn more about ancient environmental conditions on the Red Planet and how they changed over time.
This strategy gave us many prominent Mars missions over the past few decades, including the orbiters Mars Odyssey, Mars Reconnaissance Orbiter, and Mars Atmosphere and Volatile Evolution (MAVEN); the rovers Spirit, Opportunity and Curiosity; and the Phoenix lander.
These robotic explorers did their jobs well, finding lots of evidence that ancient Mars was quite wet and helping scientists better understand why, how and when the Red Planet transitioned to the frigid desert world it is today. Curiosity has taken this work the furthest, finding that its landing site, the 96-mile-wide (154 kilometers) Gale Crater, hosted a long-lived lake-and-stream system billions of years ago that could have supported Earth-like life.
Meanwhile, some scientists continued the hunt for Mars life, focusing on aliens that may have fallen fortuitously to Earth. Over the eons, billions of Red Planet rocks have made their way here, after being blasted into space by powerful asteroid or comet impacts. A lot of Earth material has ended up on Mars as well, but the ledger is decidedly unbalanced; the sun's powerful gravity pulls more stuff inward, toward Earth. (This extensive rock-swapping, by the way, has led some scientists to postulate that life actually arose first on Mars, then made its way to Earth later.)
In 1996, researchers announced that they'd found potential signs of life in one such Mars meteorite, known as Allan Hills 84001 (ALH84001). It was a very big deal; the result was published in the prestigious journal Science, and President Bill Clinton held a press conference about the news on the White House lawn.
The ALH84001 story ended up going down a Viking path. Other scientists picked at the claim, and a consensus emerged that the meteorite evidence was ambiguous at best. But, like Levin, the ALH84001 team held firm in its findings, and continues to do so today.
THE OCEAN MOONS
NASA and the broader exploration community weren't focused solely on Mars for all these years, of course. The Cassini-Huygens mission, which ended in September 2017, transformed scientists' understanding of the Saturn system and our solar system's potential to host alien life. That mission found that Titan, Saturn's largest moon, has a hydrocarbon-based weather system and that the frigid moon's surface harbors lakes and seas of liquid ethane and methane. Life could swim around in these seas, though it would have to be very different than the life we know here on Earth.
And the Cassini orbiter spotted geysers blasting from the south pole of another Saturn moon, the ice-covered Enceladus. This discovery, and other Cassini observations, revealed that Enceladus harbors a big ocean of salty liquid water beneath its shell.
The geysers produce a huge plume of water ice and other material, a cloud so substantial that it creates Saturn's E ring. Cassini flew through this plume on multiple occasions, gathering samples that scientists analyzed for clues about the moon's subsurface environment. The researchers found carbon-containing organic compounds and free hydrogen, the latter of which suggests the existence of a hydrothermal system in Enceladus' buried ocean. Undersea hydrothermal vents are one popularly invoked environment for the origin of life on Earth. (Cassini didn't look for signs of life in this plume material; the spacecraft wasn't equipped to do so, because nobody knew about the plume before that mission launched.)
Buried oceans are relatively common in the outer solar system, scientists have come to realize. Multiple ice-covered Jupiter moons seem to have these oceans — Ganymede, Callisto and, most intriguingly, Europa. Europa's huge subsurface sea seems to be in contact with the moon's rocky core, like the ocean of Enceladus is, making possible a range of complex chemical reactions that could theoretically have led to life. (Scientists think the oceans of Ganymede and Callisto are more boring, sandwiched between layers of ice.)
Titan seems to have a buried ocean of salty water as well, meaning the moon likely has two very different potentially habitable environments. Observations by NASA's New Horizons spacecraft indicate that liquid water may slosh beneath Pluto's surface, too.
And the list goes on. Indeed, the abundance of water worlds in the outer solar system suggests that looking for "Earth 2.0" may not be the best life-hunting strategy; most of the habitable real estate in the cosmos may be buried under ice.
These revelations about our celestial backyard have come in parallel with big news about the cosmos at large. Over the past decade or so, we have learned that our Milky Way galaxy is teeming with potentially life-supporting worlds, as Anaximander and Epicurus surmised so many centuries ago.
Much of this knowledge comes courtesy of NASA's pioneering Kepler space telescope, which operated from 2009 through November 2018. Kepler is responsible for nearly two-thirds of the 4,400 confirmed exoplanet discoveries to date, and mission data reveal that planets outnumber stars in our galaxy.
Many of those planets might bear more than a passing resemblance to Earth. Kepler found that at least 20% of Milky Way stars probably host rocky planets in their habitable zones, the just-right range of orbital distances where liquid water could persist on a world's surface.
Some of these potentially habitable worlds are just a stone's throw away in the cosmic scheme of things. For example, the nearest star to the sun — Proxima Centauri, which is about 4.2 light-years away from us — hosts a roughly Earth-size planet in the habitable zone. (This world, called Proxima b, is a prime Breakthrough Starshot target.) And the TRAPPIST-1 system, which lies 39 light-years from us, boasts seven rocky worlds, three of which may be capable of supporting life as we know it.
However, both Proxima Centauri and TRAPPIST-1 are red dwarfs, like 70% of the Milky Way's stellar population. Red dwarfs are small but very active stars, and their intense flaring may severely dampen their planets' habitability.
Kepler's legacy is being carried on by other exoplanet missions, such as NASA's Transiting Exoplanet Survey Satellite (TESS), which is expected to find thousands more alien worlds circling nearby stars, and ESA's CHEOPS probe, which aims to characterize some of these neighboring worlds.
The avalanche of exoplanet discoveries, as well as finds much closer to home, have brought astrobiology from the scientific fringe firmly into the mainstream. NASA is openly prioritizing the search for alien life these days, as some current and coming missions show.
In July 2020, for example, the agency launched the Perseverance rover, which landed in February 2021 to hunt for signs of ancient Mars life and collect samples for eventual return to Earth. Finding evidence of long-dead microbes is expected to be a very tricky task, one ideally carried out by teams of scientists in well-equipped labs studying pristine pieces of Mars specifically selected for their life-preserving potential. (The European Space Agency had planned to launch its own life-hunting Mars rover, called Rosalind Franklin, in July 2020 as well, but technical issues pushed the launch back to the next window, the fall of 2022.)
In 2024, NASA's Europa Clipper mission is scheduled to launch toward the Jupiter system. Clipper will orbit the gas giant but make dozens of flybys of Europa, characterizing the moon's subsurface ocean and scouting out good touchdown sites for a future life-hunting lander, among other tasks.
And in 2027, NASA plans to launch Dragonfly, a probe that will fly through Titan's thick, smoggy skies. Dragonfly's main goals involve investigating the complex chemistry that could set the stage for life's emergence and assessing Titan's habitability, but the rotorcraft will also search for biosignatures.
The agency will also soon start hunting for aliens much farther afield. NASA's $9.7 billion James Webb Space Telescope, the oft-delayed successor to the iconic Hubble Space Telescope, is scheduled to launch in late 2021.
One of the many things the powerful new telescope will do once aloft is probe the atmospheres of nearby exoplanets for potential biosignatures — gases such as oxygen and methane, whose simultaneous presence in a world's air would provide a strong case for life.
Three highly anticipated megascopes will begin doing similar work from the ground in the mid- to late 2020s, if all goes according to plan. The Giant Magellan Telescope and the Extremely Large Telescope will do their observing from the mountains of Chile, whereas the Thirty Meter Telescope will sit atop Hawaii's Maunakea volcano, if the telescope team and the local community can come to an agreement.Controversy over giant telescope roils astronomy conference in Hawaii
SETI activities may ramp up considerably soon, too, and not just because of Breakthrough Listen. The biggest radio telescope ever built, China's Five-hundred-meter Aperture Spherical radio Telescope (FAST), came fully online in early 2020, and searching for technosignatures is one of its many charges.
This is just a partial list of the coming life-hunting activities, of course. And the full list may eventually become gloriously ungainly, thanks to the continuing drop in the cost of building and launching spacecraft. This trend could eventually make astrobiology missions feasible for a variety of interested parties, from university groups to private citizens. Indeed, Milner has already mused about launching a life-hunting mission to Enceladus or Europa.
Some of this alien searching will continue to occur in Earth-based studies, and it won't just involve inspection of Mars meteorites. There's an ongoing search for a "shadow biosphere" on our planet — an entire tree of life separate from the one that includes bacteria, bats, birds and everything else we currently recognize as alive.
This pursuit isn't so crazy if you think about it. After all, life appeared on Earth about 4 billion years ago — very quickly, considering that our planet formed just 4.5 billion years ago and remained hot and inhospitable for a long time thereafter. So, life's emergence doesn't seem miraculous, which, in turn, implies that it could have happened here more than once.
Given the incredible abundance of potentially habitable real estate — and that's just for Earth-like life, to say nothing of the environments that could support "strange life" of various types — why haven't we found ET yet?
Nobel Prize-winning physicist Enrico Fermi famously posed this question in 1950, specifically referring to intelligent aliens. Seven decades later, the answer to the Fermi paradox remains elusive.
"Answers" is probably a better formulation, however, because multiple factors are probably working together to keep us from finding intelligent aliens. Among the foremost is the vastness of space, which makes it difficult for two civilizations to touch base. Consider: Proxima b is just 4.2 light-years away, in a galaxy 100,000 light-years wide. But 4.2 light-years is about 26 trillion miles (42 trillion km), an expanse that would take humanity's current spacecraft tens of thousands of years to cross.
Contact with intelligent aliens would require temporal and temperamental alignments as well; their civilization would have to rise in sync with ours, no mean feat in a universe that's 13.82 billion years old. And ET would have to want to reach out. That's no given, either; there are many reasons some aliens may want to keep quiet, as the METI pessimists have pointed out.
Or maybe intelligence is rare throughout the cosmos, even if life isn't. Earth has been inhabited for about 4 billion years, after all, but we've been sending out radio waves for just a century or so and launching spacecraft only since 1957. And it's tough to find faraway microbes, which presumably have not yet invented the radio.
Our technological youth may be the biggest factor of all: We've just begun the search for our cosmic neighbors, after all. And that search has mostly been halting and haphazard, conducted by small teams of dedicated researchers who've had to scrounge money to keep the lights on.
But that's changing, as the exciting new missions and instruments currently in development show. So we may start getting some answers very soon.
Evidence of ancient life on Mars has been ‘erased’, scientists say, as Nasa’s Curiosity rover has found parts of the Red Planet’s rock record has been removed.
Mars has a huge number of ancient rocks and mineralscompared with the Earth, and in order to try and gather more knowledge about the history of the planet scientists sent Curiosity into Mars’ Gale Crater.
The crater has been dried out for billions of years, and scientists have evidence that supersalty water (brines) seeped through the cracks in the lake bottom and altered the minerals below it.
Using the CheMin (Chemistry & Mineralogy X-Ray Diffraction) tool, scientists compared samples taken from two areas approximately 400 meters from each other. Surprisingly, they discovered that half of the clay minerals they expected to find in one area were missing; they were replaced with mudstones rich with iron oxides, which give Mars is red colour.
It is likely that the briny water filtered through overlaying sediment layers is the reason why the rock record has disappeared. The salty water likely originated from lakes that existed when Mars was drier, unlike the freshwater lakes which would have been present when the mudstones formed.
“We used to think that once these layers of clay minerals formed at the bottom of the lake in Gale Crater, they stayed that way, preserving the moment in time they formed for billions of years,” said Tom Bristow, CheMin principal investigator at Nasa’s Ames Research Center, in a statement. “But later brines broke down these clay minerals in some places – essentially resetting the rock record.”
Scientists believe these results show the impacts of Mars’ climate change, which took place eons ago. Nasa already knew that before Gale Crater’s lakes dried out its groundwater had moved beneath the surface, dissolving and hiding chemicals that scientists could study.
After these minerals were deposited the mudstone changed due to interactions with them in a process known as “diagenesis,” which complicates or erases scientists’ ability to understand the soil’s previous history. This also, however, creates an underground experience that could support microbial life – known on Earth as “deep biospheres”.
“These are excellent places to look for evidence of ancient life and gauge habitability,” said John Grotzinger, CheMin co-investigator at the California Institute of Technology. “Even though diagenesis may erase the signs of life in the original lake, it creates the chemical gradients necessary to support subsurface life, so we are really excited to have discovered this.”
The scientists said they were fortunate to be able to find both mudstones so close together, as they can use minerology to tell which part of the Martian rock will illuminate our search for alien life and which will not.
Amateur astronomer Kai Ly is on a roll. They rediscovered four “lost” Jupiter moons last year. Now, Ly has located a previously unknown moon orbiting the biggest planet in our solar system.
“I’m proud to say that this is the first planetary moon discovered by an amateur astronomer!” they posted June 30 in a message at the Minor Planet Mailing List (MPML), an online community of the world’s leading amateur astronomers.
Using old telescope images, Ly was able spot the unnamed satellite orbiting Jupiter, which is nearly 385 million miles from Earth. The distant planet has at least 79 moons—now 80—some so small and indistinct they can only be detected by a large telescope one month of the year. (Ly posted their data visuals in Imgur.)
To locate this satellite, Ly scoured images taken by the Canada-France-Hawaii Telescope in 2003, reports Jeff Hecht of Sky & Telescope. This dataset was the same one they used to find the four “lost” moons last year. The barely discernable satellites disappeared from view until Ly was able replot their trajectories and identify them on the images.
The amateur astronomer found the missing moons in the Carme cluster, a group of 22 space rocks with similar orbits, reports Doris Elin Urrutia at Space.com. With an average radius of 14 miles, Carme is the largest of these satellites, which NASA scientists suspect was an asteroid that broke apart into smaller parts.
This group is also where the new moon was found. (The finding was submitted to scientific journals, but has not yet been published.) Ly observed an object originally spotted by NASA in 2003 and thought it was a satellite. Ly calculated its 22-day arc using data from another observatory, the Subaru Telescope, to verify the object was in fact a moon orbiting Jupiter, reports Aubrey Clarke for The Science Times.
“In the end, I measured a total of 76 observations spanning an arc of 15.26 years (5,575 days),” Ly writes in the MPML message. “The orbit of this Jovian moon is now well-secured for decades to come, so I hereby present to you: Jupiter’s 80th moon, EJc0061 = S/2003 J 24 (provisional designation pending)!”
Another amateur stargazer Sam Deen tells is “quite impressed” with Ly’s discovery, which was made possible because observatories post data online for everyone to see and use. “The main obstacle is just getting to know what you’re doing and having the tolerance to go looking through the data for hours before turning up anything worthwhile,” Deen tells Sky & Telescope.
Ly describes their search as “a summer hobby before I return to school,” they tell Sky & Telescope. They plan to review more images in hopes of making another discovery.
“I will continue my hunt for unidentified Jovian moons in the February 2003 dataset, so stay tuned for additional Jovian moon discoveries by me in the next coming months!” Ly writes at MPML.
NASA FINALLY KNOWS WHAT IS BENEATH THE SURFACE OF MARS
NASA FINALLY KNOWS WHAT IS BENEATH THE SURFACE OF MARS
“The fact that we recorded it confirmed that the core is liquid.”
IF YOU’VE EVER TAKEN a planetary science course, or maybe just cracked open a book on the Solar System, you may have seen diagrams of the internal structure of the planets, showing their crusts, mantles, and cores.
What you may not realize, NASA Jet Propulsion Laboratory geophysicist Mark Panning tells Inverse, is that those diagrams “are cartoons and guesses,” based on gravitational measurements. The only planet whose structure scientists actually understand in detail is Earth.
We know the innards of Earth through seismology measurements — something that hasn’t been available for other planets. Until recently, this was true: According to a trioofpapers published Thursday in Science, researchers can finally confirm Mars has a large liquid metal core.
Panning is the JPL project scientist for the NASA InSight mission, which landed a seismometer on the Red Planet in 2018 and has been recording Marsquakes ever since. NASA's InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander was designed to reveal the inner structure of Mars through seismological and thermal readings taken from a landing site on Elysium Planitia, a plain along the Martian equator.
Panning and colleagues used InSight seismometer data to establish the thickness and possible structure of the Martian crust, the temperature of the planet’s mantle and make the first direct seismological confirmation of Mars’ core.
“This goes from cartoons to our actually knowing what the inside looks like,” he says.
WHAT’S NEW
In the study of Martian crust, researchers used readings of two kinds of seismic waves — P-waves and S-waves — to determine the potential structure and thickness of the crust.
P-waves are faster than S-waves, Panning says, and measuring the difference in their arrival times at the InSight seismometer allows researchers to locate a Marsquake.
Importantly, when a P-wave crosses a physical transition, such as from the mantel to the crust, “most of the energy continues on as a P-wave, but a little bit gets turned into an S-wave,” Panning says. Measuring the difference in timing of those two waves tells researchers when the waves have crossed a layer.
The researchers saw three “bumps” in the resulting data that can be explained equally well by two models.
In one model, the crust beneath InSight has two layers and is about 20 kilometers thick. In the other, the crust has three layers and is about 39 kilometers thick.
Extrapolated across the planet, this suggests the Martian crust averages between 24 and 72 kilometers thick, and “both of those are actually on the thin end of our pre-mission expectations,” Panning says. Some models had previously put the crust at 100 kilometers thick.
Meanwhile, the study examining Mars’s mantle found the structure looked at seismic waves bouncing off the surface multiple times to arrive later than P- and S-waves, Panning says, and measured their velocity to understand the consistency and temperature of the mantle.
“In order to match the velocities we observed, you have to keep the mantle relatively cool compared to the range of models we considered before we had data,” he said.
The findings mesh with the results of the crustal study since a hotter mantle under a thinner crust would result in more volcanism than is seen on Mars today, Panning added. The cooler mantle observations also drove the researchers’ estimate that the Martian crust is richer in heat-producing radioactive elements — by a factor of 13 to 20 — than the mantle.
The Martian core study used ScS waves — S-waves bouncing off the core — to define the core’s radius of around 1,800 kilometers while also confirming gravity measurements that suggested the core was liquid.
“A solid core would not have produced a strong enough reflection for us to have seen it,” Panning says. “The fact that we recorded it confirmed that the core is liquid.”
HOW THEY DID IT
The core measurements were the most difficult to obtain, Panning says, and scientists needed multiple measurements to confirm the tiny ScS-waves were real.
“None of these events are big. The biggest event we’re looking at is maybe a magnitude 3.8,” he says. “That’s a size that in California where I am, there’s a really good chance you wouldn’t even feel it, depending on how close you are.”
The measurements were made possible first by the extreme sensitivity of the seismometer, which Panning says can measure vibrations on the scale of a hydrogen atom, but also due to the measurements being done on a dry planet like Mars.
“On Earth, there’s always seismic noise that a seismometer records the oceans drive that,” he says. “Our seismometer on Mars is probably two orders of magnitude quieter than the best station on earth.”
WHY IT MATTERS
Earth is really why research on the deep interior of Mars matters.
Earth is a rocky planet, as are Mercury, Venus, and Mars, and understanding the formation and evolution of other rocky planets is key to understanding the one we call home.
“If you want to be a doctor and you only study one patient, you’re not going to be a very good doctor,” Panning says.
WHAT’S NEXT
The next steps for Panning’s team will be to dig deeper into the data they have now, but with InSight scheduled to keep operating into 2022, they are also continuing to record Marsquakes.
If they get lucky enough to measure some quakes at different ranges than their current measurements, it might even allow them to resolve whether the two or three-layer model of the Martian is correct.
“The story is not over,” he says. “We have to wait and see.”
Martian Crust Study abstract:
A planet’s crust bears witness to the history of planetary formation and evolution, but for Mars, no absolute measurement of crustal thickness has been available. Here, we determine the structure of the crust beneath the InSight landing site on Mars using both marsquake recordings and the ambient wave field. By analyzing seismic phases that are reflected and converted at subsurface interfaces, we find that the observations are consistent with models with at least two and possibly three interfaces. If the second interface is the boundary of the crust, the thickness is 20 ± 5 kilometers, whereas if the third interface is the boundary, the thickness is 39 ± 8 kilometers. Global maps of gravity and topography allow extrapolation of this point measurement to the whole planet, showing that the average thickness of the martian crust lies between 24 and72 kilometers. Independent bulk composition and geodynamic constraints show that the thicker model is consistent with the abundances of crustal heat-producing elements observed for the shallow surface, whereas the thinner model requires greater concentration at depth.
Martian Mantle Study abstract:
For 2 years, the InSight lander has been recording seismic data on Mars that are vital to constrain the structure and thermochemical state of the planet. We used observations of direct (PandS) and surface-reflected(PP, PPP, SS, andSSS) body-wave phases from eight low-frequency marsquakes to constrain the interior structure to a depth of 800kilometers. We found a structure compatible with a low-velocity zone associated with a thermal lithosphere much thicker than on Earth that is possibly related to a weak S-wave shadow zone at teleseismic distances. By combining the seismic constraints with geodynamic models, we predict that, relative to the primitive mantle, the crust is more enriched in heat-producing elements by a factor of 13 to20. This enrichment is greater than suggested by gamma-ray surface mapping and has a moderate-to-elevated surface heat flow.
Martian Core Study abstract:
Clues to a planet’s geologic history are contained in its interior structure, particularly its core. We detected reflections of seismic waves from the core-mantle boundary of Mars using InSight seismic data and inverted these together with geodetic data to constrain the radius of the liquid metal core to 1830 ±40 kilometers. The large core implies a martian mantle mineralogically similar to the terrestrial upper mantle and transition zone but differing from Earth by not having a bridgmanite-dominated lower mantle. We inferred a mean core density of 5.7 to 6.3 grams per cubic centimeter, which requires a substantial complement of light elements dissolved in the iron-nickel core. The seismic core shadow as seen from InSight’s location covers half the surface of Mars, including the majority of potentially active regions—e.g., Tharsis—possibly limiting the number of detectable marsquakes.
NASA investigates renaming James Webb telescope after anti-LGBT+ claims
NASA investigates renaming James Webb telescope after anti-LGBT+ claims
Some astronomers argue the flagship observatory — successor to the Hubble Space Telescope — will memorialize discrimination. Others are waiting for more evidence.
NASA is considering whether to rename its flagship astronomical observatory, given reports alleging that James Webb, after whom it is named, was involved in persecuting gay and lesbian people during his career in government. Keeping his name on the US$8.8-billion James Webb Space Telescope (JWST) — set to launch later this year — would glorify bigotry and anti-LGBT+ sentiment, say some astronomers. But others say there is not yet enough evidence against Webb, who was head of NASA from 1961 to 1968, and they are withholding judgement until the agency has finished an internal investigation.
The JWST, which will peer into the distant reaches of the cosmos, is NASA’s biggest astronomical project in decades, so the stakes are high. In May, citing Webb’s purported involvement in discrimination, four prominent astronomers launched a petition to change the telescope’s name. It has amassed 1,250 signatories, including scientists who have been awarded observing time on the telescope.
Coronavirus pandemic threatens launch of world's most-expensive telescope
NASA’s acting chief historian, Brian Odom, is working with a non-agency historian to review archival documents about Webb’s policies and actions, according to agency officials. Only after the investigation concludes will NASA decide what to do.
“We must make a conscious decision,” Paul Hertz, head of NASA’s astrophysics division, told an agency advisory committee on 29 June. “We must be transparent with the community and with the public for the rationale for whichever decision we make.”
Searching the archives
Former NASA administrator Sean O’Keefe named the JWST after Webb in 2002, when the telescope was in the early stages of development. It was a unilateral decision that took many by surprise, because NASA’s telescopes are typically named after scientists. Webb, who died in 1992, was a bureaucrat who held several administrative roles in the US government.
O’Keefe chose the name because Webb had advocated that NASA keep science as a key part of its portfolio in the 1960s, even as the Apollo programme of human space exploration soaked up most of the agency’s attention and budget. O’Keefe tells Nature he was not aware of the accusations when he picked the name, and he supports keeping it unless more information surfaces. “Without James Webb’s leadership, there may have been no telescope or much of anything else at NASA noteworthy of a naming controversy,” he says.
As Webb was beginning his career with the US government in the late 1940s, gay and lesbian employees were being systematically rooted out and fired because of their sexual orientation — a campaign encouraged by several prominent members of Congress. The period is known as the lavender scare, echoing the anti-Communist ‘red scare’ with which it was often intertwined. During the lavender scare, gay people were cast, untruthfully, as perverts who might be desperate to keep their sexual orientation secret and thus be susceptible to revealing government secrets under blackmail. Its epicentre was the Department of State, which handles foreign policy.
The four astronomers leading the renaming petition say that when Webb worked for the state department in the high-ranking position of undersecretary from 1949 to 1952, he passed a set of memos discussing what was described as “the problem of homosexuals and sex perverts” to a senator who was leading the persecution. They point to records found in the US National Archives by astronomer Adrian Lucy at Columbia University in New York City. “The records clearly show that Webb planned and participated in meetings during which he handed over homophobic material,” the petition leaders wrote earlier this year in an opinion piece in Scientific American.
US astronomers plot wish list for the next decade
The four astronomers are Lucianne Walkowicz at the Adler Planetarium in Chicago, Illinois; Chanda Prescod-Weinstein at the University of New Hampshire in Durham; Brian Nord at the Fermi National Accelerator Laboratory in Batavia, Illinois; and Sarah Tuttle at the University of Washington in Seattle. “We felt that we should take a public stand on naming such an important facility after someone whose values were so questionable,” they write in an e-mail to Nature. “It’s time for NASA to stand up and be on the right side of history.”
David Johnson, a historian at the University of South Florida in Tampa who wrote the 2004 book The Lavender Scare, says he knows of no evidence that Webb led or instigated persecution. Webb did attend a White House meeting on the threat allegedly posed by gay people, but the context of the meeting was to contain the hysteria that members of Congress were stirring up. “I don't see him as having any sort of leadership role in the lavender scare,” says Johnson.
Walkowicz and their colleagues note that as a leader, Webb bore responsibility for discriminatory policies enacted at his agency. They also note the case of Clifford Norton, who was fired from his job at NASA because he was suspected to be gay in 1963, when Webb was NASA administrator. “We believe the known historical record speaks clearly in favour of renaming the telescope,” they say.
NASA has given no estimate of when its investigation might be complete. Odom says that the COVID-19 pandemic has limited historians’ access to archival records.
A reflection of values
The push to rename the telescope falls into the broader reckoning over naming buildings, facilities and other objects after questionable historical figures. Last year, an aerospace executive began an as-yet unsuccessful effort to rename a NASA centre in Mississippi that is named after John Stennis, a senator who voted repeatedly in favour of racial segregation in the 1960s. In the past year or so, NASA has tried to address past discrimination against Black scientists and against women by naming its Washington DC headquarters after Mary Jackson, the first Black female engineer at the agency, and announcing that the flagship space telescope after the JWST will be named after Nancy Grace Roman, NASA's first chief astronomer.
Delays mount for NASA’s $8-billion Hubble successor
The JWST debate comes near the end of a long and exhausting push to launch the observatory into space. Originally conceived in 1989 as the successor to the iconic Hubble Space Telescope, the craft is many years and billions of dollars over budget.
To some, the telescope’s potential to transform astronomy makes it even more important that the JWST carry a name that reflects modern values. “For me, it really comes down to what kind of message we want to send to the more junior folks and students in our field,” says Peter Gao, a planetary scientist at the University of California, Santa Cruz. “The people we choose to celebrate by naming our telescopes after them is a reflection of our values.”
The final decision lies with NASA administrator Bill Nelson, who has not said anything publicly on the matter. There is no clear list of alternative names, although many people have made unofficial suggestions. Walkowicz and the other astronomers who are leading the petition suggest Harriet Tubman, after the formerly enslaved woman who fought to end slavery in the United States in the nineteenth century and used the stars to guide Black people to freedom. Saurabh Jha, an astronomer at Rutgers University in New Brunswick, New Jersey, suggests Cecilia Payne-Gaposchkin, whose work revolutionized astronomers’ understanding of the composition of the Universe in the early twentieth century.
Hubble telescope spies water raining on distant world
Some astronomers who plan to use the JWST are already thinking about what they will do if the telescope is not renamed. One idea is to acknowledge LGBT+ rights in the acknowledgements sections of papers published using JWST data, says Johanna Teske, an astronomer at the Carnegie Institution for Science in Washington DC.
Many are keen to see what the NASA investigation might unearth. “It’s important to look at what happened and what the facts are,” says Rolf Danner, an astronomer at NASA’s Jet Propulsion Laboratory in Pasadena, California, who is chair of the American Astronomical Society’s committee on sexual orientation and gender minorities in astronomy. “And then really ask ourselves — would we make that choice again?”
They will look for evidence of technologies crafted by intelligent alien civilizations.
Are there intelligent extraterrestrial civilizations capable of building technologies that can travel between the stars? An international research project is poised to find out.
The Galileo Project, helmed by a multi-institutional team of scientists led by Avi Loeb, a professor of science in the Department of Astronomy at Harvard University, will seek and investigate evidence that could represent defunct or still-active "extraterrestrial technological civilizations," or ETCs, project representatives said in a statement released on Monday (July 26).
The project will analyze data from astronomical surveys and telescope observations, and design new algorithms using artificial intelligence (AI), in order to identify potential interstellar travelers, alien-built satellites and unidentified aerial phenomena (UAP), according to the statement.
"Science should not reject potential extraterrestrial explanations because of social stigma or cultural preferences that are not conducive to the scientific method of unbiased, empirical inquiry," Loeb said in the statement. "We now must 'dare to look through new telescopes,' both literally and figuratively."
Loeb, who is also director of the Institute for Theory and Computation at the Harvard-Smithsonian Center for Astrophysics, has previously suggested that the oddball cosmic object 'Oumuamua — which passed by Earth in 2017 and was widely identified as a comet or asteroid — was an example of alien tech. 'Oumuamua was visible only briefly before it continued on its journey to distant stars, and its flattened, cigarlike shape and erratic motion stymied many astrophysicists; Loeb was one of several scientists who proposed that the object could be a type of spacefaring equipment made by extraterrestrials, Live Science previously reported.
"We can only speculate whether 'Oumuamua may be explained by never-seen-before natural explanations, or by stretching our imagination to 'Oumuamua perhaps being an extraterrestrial technological object, similar to a very thin lightsail or communications dish, which would fit the astronomical data rather well," Loeb said.
'Oumuamua was our solar system's first interstellar visitor (that we know of, at least), but that doesn't mean it'll be the last, and one of the Galileo Project's research branches will focus on developing strategies for finding and tracking such objects, from space and from ground-based telescopes. Other project research areas will include searching for small ETC satellites that may be observing Earth, and analysis of UAP sightings.
UAPs — also known as unidentified flying objects, or UFOs — are of particular interest now, following the recent release of an unclassified report by the Pentagon describing UAP sightings by members of the military, Loeb said. Of the 144 UAP sightings between 2004 and 2021 that were documented in the report, just one was identified with "high confidence" — as a deflating balloon. The rest remain unexplained, Live Science reported.
"Rigorously validated" evidence
The Galileo Project, not to be confused with Rice University's Galileo Project (an online resource for information on Galileo Galilei's life and work) likewise takes its name from the pioneering Italian astronomer, who lived from 1564 to 1642. Galileo used telescopes of his own design to observe celestial objects, leading to astonishing discoveries such as lunar craters, Saturn's rings and the four moons of Jupiter, according to a biography by Live Science sister site Space.com.
Galileo's observations and research also confirmed the then-controversial hypothesis of 16th-century astronomer Nicolaus Copernicus: that Earth — and all the solar system's planets — orbited the sun, rather than everything rotating around Earth. Should the Galileo Project discover "rigorously validated scientific evidence of extraterrestrial technology," the impacts would reshape scientists' perception of the cosmos, much as Galileo's discoveries did centuries ago, project representatives wrote in the statement.
Whether or not the Galileo Project will definitively settle the question about intelligent extraterrestrials' existence (and their purported technological prowess) remains to be seen. But actively searching for such physical evidence greatly improves the chances of finding the first examples of alien tech, according to the statement.
As the project's namesake Galileo wrote in "Dialogue Concerning the Two Chief World Systems" in 1632: "All truths are easy to understand once they are discovered — the point is to discover them."
An ancient road as well as the remnants of a dock and structures were found submerged in a lagoon located in Venice, Italy. While there is a lagoon there now, this proves that the location once had some dry land. The discoveries were located in the Treporti channel in the northern part of Venice’s outer lagoon.
A research team conducted sonar scans and archaeological dives in the channel and that’s when they discovered several stones that had an ovoid underside and a smooth upper face that were very similar to Roman basoli which were stones that were used to pave the upper surfaces of ancient roads.
Additionally, they found 12 archaeological structures within a distance of 1,140 meters (3,740 feet). They measured as high as 2.7 meters (9 feet) and 52 meters in length (171 feet) and could have possibly been part of a road-bed. Then they located other structures around 9 meters (30 feet) underneath the road that might have been part of a dock.
Remains of an old dock were found.
They even found the remains of what they believe were several settlements that were located along the ancient road such as bricks, roof tiles, and even pottery.
Based on what they found, the researchers think that the road connected the dock and settlements to several additional roads that connected other towns in the southern portion of the now-lagoon to the northern Roman trading center of Altinum. Although there would have been lots of dry land in that area during that time, there would have also been a decent amount of water – the sea coast would have been on the eastern side of the road while an enclosed waterway would have been on the other side.
As for when the road and settlements were constructed as well as how long they were in use for, the researchers aren’t entirely sure but they are hopeful that radiocarbon dating will help to answer those questions. (A reconstructive photo of the road can be seen here.)
(Not the old road found in Venice)
In an email to Live Science, Fantina Madricardo, who is a geophysicist at the Institute of Marine Science (ISMAR) in Venice, stated, “The Venice lagoon formed from the main sea-level rise after the last glaciation, so it’s a long-term process,” adding, “We know that since Roman times — about 2,000 years — that the sea level there rose [up to] two and a half meters [8 feet].”
The study was published in the journal Scientific Reports where it can be read in full.

There has been a disconcerting habit in recent years of even credible, trusted news sources to report fake news. It may not always be explicitly on purpose, but these sources have been known to put forward amazing content which is only very loosely disguised as being anything but real. Chief among this worrying trend are TV shows that have sprung forth from traditionally educational outlets, which have served to confuse people, spread misinformation, and inspire debate as to their reality. Here are some of the worst offenders.
Perhaps one of the most famous hoax “documentaries” ever was one involving an alleged alien body. The stunt took the form of a video supposedly obtained from a retired military officer stationed at none other than Area 51 in Roswell, New Mexico, by a British music and video producer named Ray Santilli. Released in 1990, the footage is black and white and very grainy, purportedly showing a skinny alien body with large eyes and an oversized head being dissected by a team in biohazard suits at the top-secret facility. Santilli was very precise in the details he gave about the video, explaining how many rolls of film it had been on and even how much it cost him to procure them, and the video was widely taken to be the real deal. The “documentary” spread to over 30 countries, capturing the imaginations of the countless people who thought that this was finally the real evidence of what was going on at Roswell, and the “Alien Autopsy Film” became an absolute sensation at the time.
Although there were obviously skeptics, there were also enough testimonies by supposed photographic experts and special effects wizzes proclaiming how real it all looked and how difficult it would be to fake it that a lot of people believed. It would alas be proved to be a hoax once and for all when Santilli himself admitted to the fraud. In 2006 he came forward to explain that the “Alien Autopsy” was all faked and even how he had done it, but even then there was some mystery remaining, as he claimed that although the “documentary” he had released was bogus, it had been a re-creation based frame by frame on real footage that had simply been too deteriorated to release. Hmmm. Whether there was ever another “real” video or not, this hoaxed footage has not aged particularly well, and looking back on it seems almost absurd that so many people were taken in by it, believing this now admittedly very fake looking alien dummy to be real, but believe it they did. While the alien autopsy video was a supposed “leaked video” and perhaps does not meet the strict criteria of a documentary, it unfortunately set the stage for numerous faked documentaries throughout the years. Particularly notorious for these are what would normally be traditionally considered to be legitimate sources for credible documentary programming, namely the History Channel, the Discovery Channel, Animal Planet, and the National Geographic Channel. These are beloved channels that do indeed provide quality, very educational programming, yet in recent years there has been a tendency to release more and more spectacular programs of what are often referred to as “mockumentaries.”
These are programs which go through great lengths to pass as genuine documentaries, presenting realistic footage, evidence, interviews with eyewitnesses, and talks with various “experts” within the field. The programs are extremely convincing in their portrayal of events, and although they are usually marked as at least partially fictional in fleeting disclaimers at the beginning and end of the programs, to the causal viewer they seem to be the real deal, and indeed they are obviously meant to be taken that way. Mixed within the realistic depictions of various phenomena, these documentaries make heavy use of “expert testimony” which is often gained through less than reputable means. Real experts are often led along a manipulative, misleading line of questioning meant to draw out the answers that producers seek, which are then edited in such a way as to seem to be endorsements for whatever mystery the show is peddling. If an expert is not available, then the interview is simply faked with actors posing as professionals, with credentials that cannot be traced, and even the eyewitness testimonies can be faked with actors. “Found footage” and photographs are spruced up with clever CGI and spliced together to complete the ruse. The end result is a program that on the surface for all intents and purposes genuinely feels like an authentic documentary portraying real events and exhibiting honest expert opinions, yet which is at its heart a farce, with only very fleeting blink-and you’ll miss-it disclaimers labelling the programs as for entertainments purposes only.
One of the worst offenders in recent memory was in 2012, when the Discovery Channel and Animal Planet aired a show entitled Mermaids: The Body Found, which was created to seem like an actual documentary which followed the the research of a scientific team investigating the footage of a mysterious body purported to be that of a real mermaid. The scientists claimed that an autopsy had been performed on a dead mermaid and that the government had swooped in and covered the whole thing up. It was all done very convincingly. The show made it a point to make everything seem as realistic as possible, using serious, authentic looking interviews with “scientists” who were actually actors, a somber documentary tone throughout, facts seamlessly woven in with fiction, and realistic computer generated footage to give the implication that it was a factual documentary. For all appearances, the program seemed to be an authentic documentary program, and although there was a disclaimer at the end of the program alerting viewers to the fact that what they were viewing was a fiction based on “scientific theory,” this was not prominently shown, and was more of an easily missed tacked-on message. As a result, the vast majority of viewers went away believing that what they had seen was a legitimate documentary and that mermaids had been found to be real.
A follow-up program on Animal Planet in 2013 entitled Mermaids: The New Evidence, raised the stakes in sensationalism, and truly propelled the hoax into the stratosphere. The program was similarly made in a very realistic looking documentary style and opened with a bang. The first scene showed purported “new footage” of a mermaid taken by a cellphone, which shows the creature sliding off of a rock into the ocean. Upping the ante was another piece of footage which claimed to be of a mermaid encounter in the Greenland Sea. This clip shows a webbed hand touching the window of a submersible, as well as the ghostly face of a purported mermaid blooming out of the dark before the creature darts off. The footage was all fake, but looks quite convincing and is ostensibly presented as the real deal. The show adds in very professional looking interviews with the “biologist” Dr Paul Robertson, as well as a “former scientist” with the National Oceanic and Atmospheric Administration (NOAA), who talked about the existence of mermaids and both of which were actually actors. Topping off the whole illusion, the network actually made a spin-off website, which simply informed visitors that it had been shut down by the U.S. Department of Justice and the Department of Homeland Security. The whole thing was so well done that Ed Stockly of the LA Times said of it:
It’s remarkable how well this fake documentary mimics actual programs claiming to reveal actual creatures. Substitute Mermaids for Bigfoot, Chupacabra, the Loch Ness monster, ghosts and aliens, and it’s hard to make a distinction between what’s real but faked, and what’s really fake.
The sensational program attracted 3.6 million viewers, by far Animal Planet’s largest audience ever. Unfortunately, although the network had included a fleeting, easy-to-miss disclaimer at the end, most of these viewers were convinced that it was all real. Immediately following the airing of Mermaids: The New Evidence, social networking sites such as Twitter were exploding off the charts with talk of the amazing footage, and clips of the videos were streamed at a phenomenal rate. In the end, millions of people were duped by the program, to the point where the real National Oceanic and Atmospheric Administration would go on to totally dismiss the whole thing, saying Mermaids: The New Evidence is just entertainment. No evidence of aquatic humanoids has ever been found.” Many people expressed a good amount of anger when they found out they’d essentially been tricked, and social media came alive once again with those voicing their disappointment and frustration at the network.
Although there were the disclaimers announcing the shows as based on speculation and fiction, Animal Planet did very little to make sure that these were visible or prominent, and indeed did very little to let audiences know that the programs were bogus at all. In a press release for the program, the network went through great lengths to sound official and expound on “scientific facts,” pertaining mostly to the generally dismissed Aquatic Ape Theory, a theory that humans went through a phase of aquatic evolution, yet there were only two fleeting references to the show being science fiction in the entire 1,000 word statement. All of this has led to the idea that Animal Planet may have intentionally misled people on the nature of the programs. The show’s executive producer, Charlie Foley, even personally stated that they had wanted viewers to think of it as real, and that this was the reason they had chosen the documentary format. He would say to ABC News of the programs:
We wanted people to approach the story with a sense of possibility and a sense of wonder. Hopefully that’s what Mermaids allowed viewers to do…allowed them to suspend their disbelief.
Although it is unclear whether Animal Planet willfully intended to trick its audience and create a widely believed hoax, they probably weren’t too upset about the whole thing considering the record smashing ratings the shows generated for them. It is unfortunate that this success has ensured that other such fake documentary style programs have become popular and continue to be made, with Animal Planet and the Discovery Channel, two mostly well-respected wildlife networks, being the primary culprits. Another repeat offender in shamelessly sensationalist mockumentary programming is Discovery Channel’s “Shark Week.” In recent years, the network has increasingly upped the ante on turning up the spooky factor with its annual Shark Week episodes, becoming more and more brazen. During Shark Week, the Discovery Channel has released several of these mockumentaries, which have served to draw in viewers and have the unsuspecting masses buy the whole thing hook, line, and sinker.
For instance, the Discovery Channel released several high profile such programs for several years running concerning the continued existence of the Megalodon, and these often involved supposed stories of aggressive attacks by the beasts. In 2013 and 2014, the network released two programs entitled Megalodon: The Monster Shark Lives and Megalodon: The New Evidence. The programs offered up several pieces of supposed photographic evidence for the continued existence of the Megalodon, such as one photo purportedly showing a monster shark cruising past a Nazi U-boat during World War II in what is advertised as a “declassified image.” The photo was claimed to show a shark estimated as being around 100 feet long, and at first glance seems to be genuine, but it turns out that according to many astute commenters it was very likely a complete fake or at least heavily doctored. Other photos presented showed half-eaten whales and extremely large sharks swimming off shore, all of which are of unknown and questionable authenticity. There are also presented sonar readings claimed to be of massive sharks far larger than any currently known to exist.
The same programs presented the harrowing tale of a South African vessel that was purportedly attacked by a Megalodon, killing four of its crew members. The footage is presented as a sort of “found footage” scenario from a crew aboard a charter fishing vessel on April 5, 2013 in Hout Bay, South Africa. The video purportedly shows a very large, unknown animal aggressively capsizing the boat either through ramming it or biting it, which allegedly had six people aboard. According to the show, the bodies of four of those aboard were never recovered. The video is presented as absolutely real, and the program goes through great lengths to reinforce the genuine feel of the whole incident, even showing purported news footage in the aftermath that seems to show a news conference with South African authorities speaking on the frightening incident. The problem with this whole amazing account is that follow up investigation has not been able to turn up any official reports or news items that the whole incident ever happened at all, and the South African media seems surprisingly silent on the matter, leading many to suspect the whole thing was a clever, well orchestrated fake. In an article called Megalodon — The Monster Shark Lives! (Not), dinosaur expert Bob Strauss criticized the whole alleged incident, saying:
What can you say about a TV documentary in which the suspiciously good-looking lead protagonist — “marine biologist” Collin Drake — comes up empty in a Google search? Or, for that matter, his equally attractive “marine biologist” pal Madelyn Joubert, who joins him halfway through the show, and whom a cursory web search easily demonstrates not to exist? And, not to belabor the point, a TV show that starts with suspiciously staged-looking video footage of a charter boat capsizing off the coast of South Africa, and no references can be found about this accident (in which three passengers were supposedly killed) from reliable online news sources? I don’t know much about charter boats, but I do know that people whose ship is in the process of sinking do not take the trouble to center their subjects on frame.
Another rather dramatic incident portrayed in the program is the tale of a group of marine biologists who claimed to have tagged a terrifyingly massive shark from a shark cage. The huge shark was tagged and is then said to have lurched at them and then to dive at great speed down to a depth beyond which any known shark is capable of. Although the team claims they did not get a good look at the creature, they are fairly certain it was a monstrous shark, perhaps a living Megalodon. Unfortunately, it is nearly impossible to tell how real any of this account is. Another Shark Week program aired in 2014 called Shark of Darkness: Wrath of Submarine, outlines the tale of a colossal, 35-foot long shark, named Submarine, which is said to prowl the South African coast attacking boats and whales. The legendary shark was supposedly first spotted in 1970, after which it is said to have stalked these waters and frequently capsize fishing vessels or ravaged sea life. The program claims that Submarine is well known by locals, and provides interviews with eyewitnesses who have seen it, but it is unclear whether these witnesses are genuine or merely actors. The Discovery Channel attached to the show an easy-to-miss disclaimer noting that the material presented is “based on rumor and hearsay,” but does not actually admit to faking anything. Nevertheless, Submarine is supposedly still sighted to this day. Is it a real cryptid or something totally created by the program? It is hard to say.
In response to the outcry and accusations of misleading the public with these programs, the executive producer of Shark Week, Michael Sorensen, stated that three disclaimers had been aired with the shows, including one which read “none of the institutions or agencies that appear in the film are affiliated with it in any way, nor have approved its contents.” Other disclaimers stated “certain events and characters in this film have been dramatized,” and that “legends of giant sharks persist all over the world; there is still debate about what they may be.” However, these disclaimers still manage to cleverly avoid outright admitting any blatant fakery, and it is uncertain just what “dramatized” means in relation to the programs or to what extent it is used. Sorensen was similarly evasive when he commented on the shows, saying:
With a whole week of Shark Week programming ahead of us, we wanted to explore the possibilities of Megalodon. It’s one of the most debated shark discussions of all time, ‘can Megalodon exist today?’ It’s (the) ultimate Shark Week fantasy. The stories have been out there for years and with 95 percent of the ocean unexplored, who really knows?
Regardless, like the Mermaid mockumentaries, the Megalodon shows managed to smash ratings records, becoming the most watched episodes of Shark Week ever aired, so people are obviously interested in the topic. How much of the programs was true and how much is whole cloth fabrications? Is there any merit to what was presented in these shows concerning the Megalodon or is it all just pure made-up hogwash? It is difficult to tell, and the network remains quite ambiguous and evasive about the whole thing. Until a serious documentary that is more interested in informing than in sensationalism, entertainment, and getting ratings, it is probably best to take whatever is presented in these types of programs with a healthy grain of salt. Sadly, there was a time when the Discovery Channel was a place where one could usually rely on getting such genuine, educational documentaries.
Adding to the deceptive quality of such programming is the fact that these shows sometimes get real scientists to appear on them through false pretenses, trickery, and outright lies. When making a fake Shark Week documentary called Voodoo Sharks, about a legendary monster shark called the Rooken, which said to lurk in the swamps and bayous of Louisiana, Discovery Channel approached biologist and shark expert Jonathan Davis to appear. When Davis went to meet with the film crew out in the field, his inquiries as to what exactly the show would be about were continually deflected or even ignored. The frustrated scientist was only able to glean that they were supposedly making a program about shark research in Louisiana. When the show was finally aired, Davis was astonished to see that the program was about mythical cryptid sharks, which he had not been told of at all. Further adding to his shock was the fact that the show presented his interviews wildly out of context, things he had said were mixed and matched to make it seem as though he was endorsing the existence of the mystery shark, and that the interviews had been spliced together with other footage to make it seem as though he was in a race against another team to see who could find the mythical shark first. Davis would later lament that during his interviews with the crew, he had been led along certain routes and asked to say or rephrase things that would fit into what the producers wanted, including things that Davis admitted he would have never said on his own. The clever line of questioning also managed to glean responses to vague questions that could be used out of context to be responses for different questions. Indeed, this practice of deceiving and manipulating experts and their testimony has become commonplace on these cryptid “mockumentaries” and other cryptozoology shows in general.
Besides aliens, mermaids, and the Megalodon, we can’t forget about Bigfoot, and of course there is an equally misleading mockumentary about this cryptid as well. In 2015, the History Channel released Breaking History: Bigfoot Captured, which similarly used faked footage, paid actors, twisted expert testimony, and flat out lies to sell the idea that a Bigfoot had actually been caught. The program starts on the premise that a researcher has actually managed to capture a specimen, but really just follows a fake, paid actor posing as someone trying to capture one, and it really goes all out in sensationalizing Bigfoot in a major way. Predictably, the program brings in experts, in this case anthropologist Dr. Jeffrey Meldrum, who would go on to very publicly denounce how badly his words were misrepresented in the show, and it also features a badly rendered CGI rendition of a Bigfoot actually captured and locked in a cage. The whole thing is really over the top, but actually created a Twitter storm of people wondering if it was real or not. The shamelessness of this show was very amusingly broken down by Jim Vorel, at the site Paste, who does not mince words when he says:
This style of BS programming has now been refined into a science of its own. The narrative elements are careful in going out of their way to not “tell you what to believe,” or at least not directly. Instead, they present you with mounds of fake evidence and rely on the impressionable viewer to “come to their own conclusion.” Ignorant, close-minded skeptic characters are used as straw men to shoot down any potential arguments before they’re raised. It all taps into the same desire that fuels conspiracy theorists in general—the desire to be a possessor of secret knowledge, to feel intelligent. The History Channel execs understand that the more ignorant portions of their audience desperately want to feel like they belong to a fraternity of people with knowledge that “they” (whoever the hell ‘they’ are in this scenario) DON’T WANT YOU TO KNOW. Perhaps they already believe these sorts of things—in that case, Bigfoot Captured simply triggers their confirmation bias.
In order to be on History Channel in the first place, the program has to make some sort of claim toward veracity—hence, the fake documentary format. Simultaneously, in order to not be called charlatans, the official position of History Channel has to be “people are just watching to be entertained, no one is taking this seriously.” SIMULTANEOUSLY, the show has to be believable enough to still fool people, because if it didn’t, no one would be watching. Just writing that makes my brain want to gnaw its way out of my skull, seeking sweet freedom.
The problem is that no, not everyone knows it’s entertainment. And if you’re intelligent enough to know that, then you should also realize that it’s the impressionable people watching who most need a source they can actually trust in order to provide real information. These people don’t need entertainment. They need a network that’s actually serving their best interest—and for the record, their best interest is “Not having pseudoscientific beliefs that they’ll pass on to anyone in earshot.” This is the responsibility that History Channel claims it’s upholding when a two-hour long program is preceded by a disclaimer on screen for a few seconds saying that the program features “some dramatization.” At least, that’s what I’m told appeared, because I started watching 60 seconds after the program began. For me, and anyone else who joined at any other point during that ludicrous 120-minute runtime, there was zero other indication that you were seeing anything other than an (admittedly shitty) documentary. Not until the end credits, with its clear listing of actors in the “scripted story” segments, do they come close to admitting what you’ve been watching that whole time. Good thing that American audiences always closely monitor TV credits, right? Congratulations, History Channel. You’ve truly earned the title of “that network with less dignity than ABC Family.” Be proud.
Even if the networks are not intentionally trying to deceive audiences, there are obviously dishonest practices going on in the way they are presented for the purpose of generating maximum mystery and intrigue, provoking belief in the fantastic, and giving the audience what they want to see. Whether the ultimate goal is outright deception or not, these sly television programs do a lot of damage to the credibility of any potentially real discoveries or footage found. It seems at the very least that it would be helpful to make more of an effort to more prominently show that these programs are fictional, and to present interviews with scientists and experts in a more honest manner. It seems that in this day and age, with the blooming popularity of paranormal programming, it is probably best to view most shows on the matter with a grain of salt.

Mijlpaal voor Marshelikopter: meer dan 1,6 kilometer gevlogen over rode planeet
Mijlpaal voor Marshelikopter: meer dan 1,6 kilometer gevlogen over rode planeet
De Markshelikopter Ingenuity heeft een nieuwe mijlpaal bereikt. De helikopter heeft meer dan een mijl (1,6 kilometer) over de rode planeet gevlogen. Dat maakt NASA zelf bekend.
NASA meldt dat Marshelikopter Ingenuity intussen tien vluchten heeft gemaakt over de rode planeet. In totaal heeft het toestel meer dan één mijl (1,6 kilometer) afgelegd, een record. Volgens de ruimteorganisatie was de laatste vlucht de meest complexe tot nog toe.
De helikopter maakte een vlucht langs tien vooraf bepaalde punten op een hoogte van ongeveer twaalf meter. Die vlucht duurde bijna 3 minuten. Dat is een stuk langer dan de eerdere vluchten van ongeveer 40 seconden. De helikopter maakte beelden van een aantal bergkammen.
Voor de Marshelikopter, die vorig jaar aan boord van het NASA-wagentje Perseverance (Volharding) werd gelanceerd, zijn de omstandigheden op Mars extreem. De rotoren moeten door de ijle atmosfeer, ruwweg maar 1 procent van die op aarde, meer dan 2.500 omwentelingen per minuut maken om los te komen van de grond. Daarnaast is de zonne-energie geringer en hebben de accu’s te lijden onder de lage temperaturen ‘s nachts, wanneer het kwik kan zakken tot 90 graden onder nul.
Hoelang de Marshelikopter nog blijft vliegen, is momenteel ook voor de wetenschappers nog een verrassing. Normaal zou de missie eind november ten einde lopen. De Marshelikopter doet echter beter dienst dan verwacht en blijft dus verder ingezet worden. “We verwachten wel dat er een einde aan komt”, zei projectmanager MiMi Aung eerder. “Het blijft een verrassing hoelang de onderdelen blijven werken.”

Possible Flying Saucer with Dome half buried in Antarctic Snow
Possible Flying Saucer with Dome half buried in Antarctic Snow
Apossible crashed UFO half buried in the snow found 6 km from an unknown station in the middle of nowhere in Antarctica.
The upper part of the disc measures 30 meters whose dome appears to have broken off during the crash.
It is said that NAZI UFO craft have been stationed in Antarctica before, during and after World War II and since the dome of the disc seems to have been built in the last century, we may wonder whether it is a NAZI UFO eg a Glocke as well as could it be that this station has served as air traffic control for NAZI UFOs in the past?
WHAT DO A MIGHTY morphing dinosaur, several children in a trench coat, and a swarm of smiling robots have in common? They know there’s power in numbers — at least when it comes to their constituent parts.
Megazord from the Power Rangers franchise and the Teselecta from Doctor Who are examples of superstructures, or a structure in robotics made up of tinier robots. And they’re not just science fiction anymore.
In a new paper published Wednesday in the journal Science Robotics, a team of physicists from the University of Bordeaux designed a new kind of superstructure that uses mindless mini-robots to power a seemingly intelligent superstructure that can squeeze through obstacles, pull things, and even battle other superstructure bots.
“We made them play games — we played billiards — and they do it so well that you're like, ‘The hell with it, they are intelligent!’” Hamid Kellay, a professor of physics at the University of Bordeaux and a senior author on the paper, tells Inverse. “But they’re not.”
WHAT’S NEW
When it comes to the mini-robots themselves, which Kellay calls “bugs,” he says they’re not too different from what you find in similar studies on this subject. And in fact, they’re the same kind of small, vibrating toy you might give a child or a cat. They’re roughly 1.7 inches long and less than an inch tall and colored orange and red with tiny, non-functional legs.
Using these off-the-shelf toys helps the lab cut down on time and money in 3D printing something of their own, Kellay explains.
The true significance of their studies lies in the collaborative motion they observed when a collection of the robot bugs were set loose in a thin, flexible shell — similar to putting a wind-up toy inside a rubber band. Even though these bugs are truly mindless (i.e., they’re just a plastic shell and a vibrating motor), they appear to move intelligently within the flexible scaffold.
Studying how these superstructures move through different obstacles will help the research team understand the new kinds of forces these superstructures exert, says Kellay. In other words, how they interact with the world around them.
WHY IT MATTERS
These kinds of superstructures are still in the early stages of development. Still, Kellay says they could have several practical applications in the future, including cleaning hard-to-reach or dangerously infected areas of your house.
And if they were to be scaled down much smaller in the future, these bots might one day also play an important role in the future of internal drug delivery.
Unlike complex speaking or dancing robots that might seem standard today, Kellay says that these robots and driven purely by “physics and chance.”
Here’s how they work in a nutshell:
The robot bugs are painted with small lines to help the researchers keep track of their orientation
These bugs are then let loose in a flexible scaffold on a flat surface
Turned on, these bugs vibrate and move randomly until they run into one another
Running into each other then creates a “clustering” movement where the bugs align together at a barrier
This collaborative movement at the barrier then propels the entire scaffold, or superstructure, forward
The team put these superstructures through many trials, including climbing through small openings, cleaning up obstacles, and even battling each other for supremacy.
In later trials, the team also outfitted a group of the bugs with what Kellay describes as a tiny backpack containing an extra motor, light sensor, and battery. When exposing this group of bugs to bright light, the researchers found they would change their motion from a straight line to a small orbit.
“If you have no lights, they will go straight, but if you turn the light on and turn the second motor on, they start orbiting,” explains Kellay. “This orbiting actually turns out to be very nice because when you put a bunch of these things into this scaffold when they're turning like this, they generate more collisions... and cluster faster.”
This means you need fewer bugs to accomplish the same result.
WHAT’S NEXT
In the future, Kellay says he’s interested in exploring more options for controlling these structures using flashing lights to maneuver individual bots at a time.
And as a professor, Kellay says he’s also excited for the learning opportunity these “idiotic” little bugs offer for students just getting interested in the field of physics.
“Things like this are of really of high educational value,” says Kellay. “Show this to kids, and you get them immediately interested... As a university professor, that’s very important to me.”
Abstract:
A swarm of simple active particles confined in a flexible scaffold is a promising system to make mobile and deformable superstructures. These soft structures can perform tasks that are difficult to carry out for monolithic robots because they can infiltrate narrow spaces, smaller than their size, and move around obstacles. To achieve such tasks, the origin of the forces the superstructures develop, how they can be guided, and the effects of external environment, especially geometry and the presence of obstacles, need to be understood. Here, we report measurements of the forces developed by such superstructures, enclosing a number of mindless active rod-like robots, as well as the forces exerted by these structures to achieve a simple function, crossing a constriction. We relate these forces to the self-organization of the individual entities. Furthermore, and based on a physical understanding of what controls the mobility of these superstructures and the role of geometry in such a process, we devise a simple strategy where the environment can be designed to bias the mobility of the superstructure, giving rise to directional motion. Simple tasks—such as pulling a load, moving through an obstacle course, or cleaning up an arena—are demonstrated. Rudimentary control of the superstructures using light is also proposed. The results are of relevance to the making of robust flexible superstructures with nontrivial space exploration properties out of a swarm of simpler and cheaper robots.
