Dit is ons nieuw hondje Kira, een kruising van een waterhond en een Podenko. Ze is sinds 7 februari 2024 bij ons en druk bezig ons hart te veroveren. Het is een lief, aanhankelijk hondje, dat zich op een week snel aan ons heeft aangepast. Ze is heel vinnig en nieuwsgierig, een heel ander hondje dan Noleke.

    Watch: The UFO captured on camera in 2004.

    Pentagon formally releases 3 Navy videos showing "unidentified aerial phenomena" 

    (US Pentagon)

    Sorry, believers: Skeptics say there are rational explanations for military pilots' UFO videos

    Paging Agent Mulder: The Pentagon's spectacular UFO videos all have plausible, non-extraterrestrial explanations

    MATTHEW ROZSA

    The Pentagon announced Thursday that it is creating a task force to investigate UFO sightings. Though the notion that the military is investigating UFOs sounds like a fringe conspiracy theorist's ultimate redemption, the military's actions are far from preposterous. That's because their own trusted soldiers have credibly encountered UFOs while piloting military aircraft.

    The Pentagon's footage from these sightings, which has been made public, depicts objects zooming quickly through the sky, as recorded by military pilots. Though these objects fit the technical definition of a UFO — meaning an unidentified flying object — they may not adhere to the folk understanding of "UFO" as synonymous with an extraterrestrial spacecraft. That's because there isn't exactly any evidence that these objects are of extraterrestrial origin, or that they defy any existing laws of physics that might hint at their development by a more scientifically advanced species. 

    "To understand the videos, all you need to do is ask any fighter pilot familiar with the FLIR camera system," Brian Dunning, a professional scientific skeptic and podcaster, told Salon by email. "What looks like great speed and wild maneuvers is just a common optical illusion combined with the effects of the FLIR's gimbal and glare filter." FLIR cameras, short for forward-looking infrared cameras, are capable of seeing slightly into the infrared spectrum, meaning that heat sources light up on FLIR camera footage.

    Dunning zeroed in on a released video that appears to show a bat-winged shaped craft, noting that "the object you're seeing is a single point of heat from an unidentified plane, probably a distant commercial jet, flying away from the F-18. The camera is looking out the side of the F-18 which is speeding past nearby clouds, making the object appear to be moving relative to the clouds."

    He added, "Its bat-wing shape is how the FLIR's glare filter always depicts single bright points (there are plenty of examples of this on YouTube), and whenever the object appears to turn, this is simply the FLIRs gimbal rotating to keep the target in view as the F-18 maneuvers. The other videos also have similarly prosaic explanations."

    Timothy Caulfield, a law professor at the University of Alberta who also hosts a TV series that debunks pseudoscience (titled "A User's Guide to Cheating Death"), explained to Salon that there are a number of potentially innocuous explanations — many of them involving military or other highly secretive scientific experiments — that get ignored due to sensationalism.

    "I get why people are fascinated by this topic. It's exciting, it's intriguing, it's mysterious," Caulfield said. "But the idea that these things are UFOs and alien sightings, and that there is alien material left on our planet, is scientifically implausible and highly unlikely. It's an Occam's Razor story. I think there is probably a more straightforward explanation, but we will just never know with the deep uncertainty. People want answers."

    He drew particular attention to how the pilots that spotted these UFOs may have inadvertently fanned the flames of conspiracy theorists.

    "When people look at those kinds of videos and the reaction of the pilots, for example, I think that's often also used to give them more credibility with these expert pilots, often military pilots, commenting on the behavior of the shifts," Caulfield explained. "I'm not a physicist, I'm not an engineer. I can understand what people are intrigued. They don't know what this object is and it's moving in a manner that seems impossible given our current technology."

    Alexander Wendt, an international relations professor at Ohio State University who has become a prominent amateur ufologist, pointed to the reactions of the military pilots as a sign that these new UFOs should be taken seriously.

    "I challenge anybody to do better than the Navy to explain what's in those videos. If the Navy couldn't do it..." Wendt told Salon, before adding that "they had every reason to want this off their plate."

    As Wendt pointed out, "I think what's unique about these Navy videos is that the whole issue arose from the pilots... I think the upset pilots is really a key thing. These guys are the experts on what's in the sky. They have thousands of hours of experience flying up there. You see some of the interviews with these pilots and they think something is going on, and they were the ones that pushed this whole issue to the front."

    Another Ohio State University professor, political scientist Thomas Wood, opened up to Salon about why people embrace UFO conspiracy theories.

    "If you look at the data on public opinion on this, it is really sort of incredible," Wood explained. (A Gallup poll last year found that 33 percent of Americans believe that some UFO sightings were caused by alien visitation; a YouGov poll last month found that 56 percent of Americans believe that the government would hide UFO evidence from the public.) "The American public fascination with UFOs is one of the very durable conspiracy theories in the American public's imagination. Most conspiracy theories may become popular and then quiet quickly — for instance, the Barack Obama was born in Kenya theory, the American government planned the 9/11 terrorist attack theory. The UFO conspiracy theory is one of those that just sort of stuck around."

    Dunning was quite cynical about the reasons for people believing in UFOs.

    "Two words: Sensationalism sells," Dunning emailed Salon. "Nobody is excited about the artifacts of the FLIR glare filter; everyone is excited about the prospect of the Pentagon hiding the 'truth about aliens.'"

    He added, "Humans are hardwired for anecdotal thinking. Our brains gravitate toward the simple and the desirable, and away from the complicated and the boring. The people in the business of selling TV programming are well aware of this, and that's why we see UFOs, ghosts, psychics, and miracle cures dominating pop culture."

    Many famous people claim to have encountered either UFOs or aliens, from singers Elvis Presley and Blink-182's Tom DeLonge and President Jimmy Carter. They were able to have successful careers despite the stigma associated with such an alleged experience, though many other believers were not. 

    Earlier this year, the TV series "Unsolved Mysteries" devoted an episode to a group of people from a small town in western Massachusetts who claim they encountered a UFO in 1969. They described being socially rejected, viciously bullied, and in one case even harassed to the point where they moved away. it makes sense why they wouldn't go to the police or the local press at the time with their story. Many other reports of UFO sightings and encounters follow the same pattern — those who come forward suffer for doing so. As one of the people in the episode puts it, the town devolved from "Norman Rockwell to Salvador Dali" as public opinion and un-visited citizens turned against the purported witnesses.

    Russian cosmonaut Ivan Vagner has shared a video of the aurora over Antarctica which showed several unknown objects flying through outer space

    Meteors or UFO? Russian Cosmonaut Shoots Mysterious Objects in Space – Video

    by 

    Ivan Vagner joined the ISS crew on 9 April, when a Soyuz MS-19 spacecraft sent him along with fellow cosmonaut Oleg Skripochka as well as NASA’s Andrew Morgan and Jessica Meir to the space oupost.

    Russian cosmonaut Ivan Vagner, who is currently woking on board the International Space Station, has shared a video of the aurora over Antarctica which showed several unknown objects flying through outer space.

    In the 60-second clip that Vagner posted on his Twitter page on Wednesday, at least five mysterious objects are seen emerging from the dark and slowly moving in space before completely disappearing.

    "[…] In the video, you will see something else, not only the aurora. At 9-12 seconds, 5 objects appear flying alongside with the same distance. What do you think those are? Meteors, satellites, or…”, the cosmonaut tweeted.

    He added that the footage was sent to the management of the Russian space agency Roscosmos as well as to the country’s leading rocket and spacecraft scientific centre TsNIIMash and the Space Research Institute of the Russian Academy of Sciences for "further analysis".

    Several Twitter users have, meanwhile, suggested that the "breathtaking" video captured nothing but a new batch of Starlink satellites that were launched by Elon Musk's SpaceX on Tuesday.

    Starlink is the next-generation satellite network capable of providing Earth's inhabitants with broadband internet access. The project's implementation began in February 2018 amid SpaceX’s plans to launch a total of about 12,000 such satellites into outer space.

    20 mysterious UFO sightings in Lincolnshire that still don't have an explanation

    One woman even claims to have been abducted by aliens...

    By Social Media Editor  Matty Hewitt

    Have you seen a flying saucer?

    There have been hundreds of sightings of unidentified flying objects (UFOs) around the world.

    Lincolnshire is certainly no different - there have been all sorts of strange sightings in the skies of our county over the years.

    Last year, Boston was named as one of the top ten places in the UK to spot a UFO.

    The most recent sighting - showed flickering lights the sky over the A151 near Bourne.

    This sighting is just one of a number of other, more mysterious sightings,that still can't be explained.

    Here are our picks of the weirdest UFO sightings across Lincolnshire.

    Amazing footage captures UFO sighting in sky above Lincolnshire - July 2020

    A man has captured video footage of a possible UFO flying in the sky above Lincolnshire.

    The footage, which was filmed over the A151 by Alex Platts, shows flickering lights in the sky overhead on Monday, July 27.

    He posted online: "UFO I’ve just been watching over Bourne.

    "Headed off North Easterly direction. Any ideas??"

    The video caused a stir, with a lot of people commenting with ideas of what they thought it was.

    One said: "Very odd. That’s not something easily explained.

    "I do love a good UFO sighting."

    Another suggested: "The light flashing pattern makes me think it's a helicopter."

    Alex, however, says he believes it's not a helicopter - as there was no rotor noise and the way the lights "flowed from front to back" was not like that of a helicopter.

    "It looks like several of whatever they are," another person commented.

    Mysterious object over the Lincolnshire coast - October 2019

    A man in Ingoldmells spotted this very strange image in the sky in October last year.

    The man who took the photo, Gary Couldwell, said: "It was so weird. At first I thought it was a lantern, but the way it moved in the sky I don't think it could have been.

    "It just stayed in that position for such a long time before shooting up so quickly.

    "I don't believe in any of that, really. I'm a doubter. But after this, seeing it with my own eyes - I'd say I'm inbetween."

    Shiny round object in the sky over Boston - May 2017

    In May 2017, a video of a shiny round silver object in the sky which appeared and disappeared over Boston was posted on YouTube.

    Five strange lights spotted over Lincoln Cathedral in broad daylight - April 2014

    People in Lincoln spotted five lights in a pentagon shape April 2014.

    The person who captured the footage claimed they were absolutely not Chinese lanterns and has labelled the phenomenon a UFO.

    Hovering, flashing lights spotted over Heckington - August 2013

    This example has seen plenty of exposure since it came to light seven years ago.

    An eyewitness, Pete Willerton, from Heckington, said he saw the lights from his home.

    Speaking in 2013 he said: "It looks a bit like a chinese lantern but it flashes and changes colour from orange to red to white. It moves around slightly then just disappears.

    Strange object seen over Lincoln - May 2019

    Simon Carrison photographed this object in the sky from his home in College Close, Lincoln just after 6.30pm on May 23 2019. He had no idea what the object could have been.

    Object burning in the night sky - September 2017

    In 2017, Zoe Fletcher took to Facebook at about 9pm on Monday, September 4 and wrote that she'd seen something burning through the night sky.

    She wrote: "Me and Nathan were in the garden and heard a strange whirring noise in the sky like an aircraft but ranging from low pitch to high pitch.

    "It looks like something burning through the atmosphere," she added.

    Mysterious lights floating over Skegness for seven hours - 1996

    Mysterious lights were seen in the sky over Skegness for seven hours, and the object was spotted on a military radar.

    But the RAF were told to ignore it after it was “overruled at the highest level” and files show that RAF Coningsby wanted to scramble aircraft to the scene.

    A letter from an unidentified government official criticised the government's defence secretary at the time, writing: "I am very concerned about an incident that occurred off the Anglian Coast recently, involving a visual unidentified flying craft sighting which was correlated by various different military radar systems.”

    It added that it was "incredible" that "no aircraft were scrambled when an uncorrelated target was picked up so close to the coast” and that “this raises serious issues about the way in which we police the UK’s Air Defence Region”.

    Large, dark object hovering over Lincolnshire - 2016

    This image was taken in 2016 and appears to show a mysterious dark object floating in the sky in Lincolnshire.

    It is not known exactly where the video was filmed but it was uploaded to YouTube with the title 'UFO Sighting Over Lincolnshire, UK August 20, 2016'.

    "Is it a plane or a UFO?" - May 2014

    A Lincolnshire allotment keeper spotted this mysterious object in the skies above the county.

    Hunting cameras installed to identify people breaking into sheds and stealing chickens showed a strange light in the sky.

    Allotment holder Gary Ingham said: "Is it a plane or a UFO?"

    Grimsby Live has also reported a number of strange sightings and events in North Lincolnshire.  One woman claimed to have been abducted by aliens from her home in Tetney the same day UFOs were spotted over Grimsby.

    They report some of their strangest sightings below.

    March 2000 - Woman claims to have been abducted by aliens

    A woman claimed to have been abducted by aliens at her home in Tetney on the same day UFOs were sighted over Grimsby.

    She said that at around 9.30am that morning she was transported from her bed to an alien space ship that was constructed entirely of a steel-like material.

    She explained: “I was in bed and felt myself getting weaker and weaker, like I was collapsing. The next thing I knew, I was in this corridor.”

    While on board the alien ship she opened a door and was shocked to find a human male “spread-eagled” on a table, while aliens “peeled back his skin to look at his insides”.

    The woman added: “There was a female being, who was milky white and wearing some sort of wig, I think it was to try and make her look less frightening, and more human.

    “She communicated to me, telling me not to worry about my cats and dog, that they would be looked after.

    “She didn’t speak to me in words, just put these thoughts in my head. She didn’t scare me, I think she was trying to help."

    She said she thought she was going to die, but the next thing she knew she was back in her bed and only 11-and-a-half minutes had passed.

    “I was so shocked to be back, I thought I was gone for good,” she said.

    The woman said she knew people would perceive her as “mad” but honestly believed it was a real abduction.

    September 1970 - Fatal crash sparks strange theories

    The downing of fighter jet XS894, piloted by American Captain William Shaffner on a September evening in 1970, has been officially documented as a tragic accident.

    But reports of bizarre flying transparent spheres, unusual blips on the radar and the fact the aircraft was discovered with its cockpit empty and canopy shut fast has left the story open to discussion.

    On the night of September 8 1970, Captain William Schaffner, an American pilot based at RAF Binbrook took off from the flight-line out into the skies over Grimsby and headed across the Humber, and out over the North Sea, heading to Flamborough. Shortly after 10.30pm his plane ditched into the North Sea, five miles south of Flamborough Head.

    An air and sea search and rescue operation was launched but it would take a further four days for the joint American and British operation to cease their search.

    The story has prompted much discussion and attracted conspiracy theories

    On October 7, 1970, it was revealed that the plane had been found when navy divers sailed to Flamborough onboard the HMS Kedleston but their search still did not provide answers and they returned empty handed.

    August 1999 - 'Disc' hovers over Scartho Fork

    A UFO was spotted over Scartho Fork. A vast glowing disc hovered over the roundabout and then sped upwards, according a Springfield Road resident.

    He added that he had seen the object a total of five times.

    He said: "The first time I saw the UFO, I was frightened. The disc gave off a warm red glow and then turned green.

    "The disc spun off in to the night sky, moving this way and that in an apparently random way. Who knows where it was going.''

    April 2000 - Several sightings of strange phenomenons

    Grimsby Telegraph readers flooded the telephone lines with sightings of strange phenomenons.

    A Cleethorpes couple got the shock of their lives when an unidentified red ball hurtled towards their house and passed through one of their bodies.

    A woman was on the telephone when her husband shouted to at her to look through the window.

    A woman claimed to have been abducted by aliens

    She said: ''I left the phone dangling as I saw a two-inch red ball of fire come through the window and pass through my husband's chest.

    “We immediately lifted his shirt to see if it had left a mark, but there was nothing there – we daren’t tell anyone at first, it was very frightening. People will think we’re mad but there was nothing in the sky and not a soul around.”

    The man involved said: “I’m too old to be scared, it didn’t hurt but we both saw it and my wife never drinks.”

    Meanwhile, one Cleethorpes woman's husband thought she was “cuckoo” after she told him she had seen a “bright light travelling really slowly across the sky down the Humber” when she put her washing out.

    She described the object as “round and big”.

    Another reader saw a “really bright light” hovering above Blundell Park.

    He said: “It was like a comet, it was so quick it couldn’t have been an aeroplane or a helicopter. It vanished in a split second. It was travelling at a height between 3,000 to 5,000 feet – I can’t describe it, I’ve never seen anything like it.”

    October 2003 - UFO spotted near  Freeman Street

    A couple spotted what they believe was a UFO "turning over and over in the sky" near Freeman Street in Grimsby.

    The UFO was in the air above their Bodiam Way home for several minutes before Steve went inside and grabbed his video camera.

    The footage showed an intriguing black object coming in and out of view and catching the light at regular intervals.

    September 2005 - Mysterious animal and unidentified flash

    Ashby-cum-Fenby was visited by both a UFO and a large black cat, according to a resident.

    During one weekend, his CCTV camera caught images of a mysterious animal walking in a field near his house as well as an unidentified flash.

    A couple in Ashby cum Fenby were checking through CCTV footage when they saw a large cat-like animal running through their field and also saw what looked like a UFO. This CCTV shows what they believe to be a UFO

    March 2009 - 'Protractor-shaped' flashes

    Two people saw “protractor-shaped” flashes in the sky at about 8pm on March 23. Three others spotted a multi- coloured flashing object hovering in the sky above Grimsby’s Grafton Street.

    Strange lights were spotted in the skies above Grimsby town centre in September 2019

    January 2009 - Witnesses say UFO damaged wind turbine

    Witnesses in the Conisholme area claimed damage to a wind turbine was caused by a UFO.

    One person described seeing a “massive ball of light” with “tentacles going right down to the ground”.

    The story garnered international attention as was reported on the front page of The Sun.

    It was later reported that "bolts securing the blade to the hub of the turbine failed due to material fatigue".

    September 2010 - 'Strange red aircraft  lights' spotted near Tetney

    A second appeal for sightings was printed in the Telegraph, following initial reports of “strange red aircraft lights” near Tetney earlier in the week. The story followed an e-mail from another reader who said they had “possibly just seen two UFOs travelling in an easterly direction over Fulstow village, heading towards the North Cotes area”.

    September 2019 - Unusual lights over Grimsby

    Several people got in touch to say they spotted unusual lights over Grimsby shortly before dawn one morning.

    The unidentified objects were seen flying low over the town centre and are said to have disappeared mysteriously quite suddenly. Witnesses also said there was no sound accompanying the lights.

    One picture sent to us appeared to show three distinct lights which did not seem to be connected by any visible object.

    Dwarf Planet Ceres is Water-Rich World, New Research Suggests

    High-resolution observations from NASA’s Dawn spacecraft of mysterious bright spots (faculae) in Occator crater on the dwarf planet Ceres suggest the existence of a brine reservoir — which is about 40 km (25 miles) deep and hundreds of km wide — that emerged to the surface through long-lived cryovolcanic activity as a consequence of the impact that created the crater.

    “Dawn accomplished far more than we hoped when it embarked on its extraordinary extraterrestrial expedition,” said Dawn’s mission director Dr. Marc Rayman, a researcher at NASA’s Jet Propulsion Laboratory.

    “These exciting new discoveries from the end of its long and productive mission are a wonderful tribute to this remarkable interplanetary explorer.”

    Long before Dawn arrived at Ceres in 2015, astronomers had noticed diffuse bright regions on the dwarf planet with telescopes, but their nature was unknown.

    From its close orbit, Dawn captured images of two distinct, highly reflective areas within Occator crater, which were subsequently named Cerealia Facula and Vinalia Faculae.

    Scientists knew that micrometeorites frequently pelt the surface of Ceres, roughing it up and leaving debris. Over time, that sort of action should darken these bright areas. So their brightness indicates that they likely are young.

    Trying to understand the source of the areas, and how the material could be so new, was a main focus of Dawn’s final extended mission, from 2017 to 2018.

    The research not only confirmed that the bright regions are young — some less than 2 million years old; it also found that the geologic activity driving these deposits could be ongoing.

    This conclusion depended on scientists making a key discovery: salt compounds concentrated in Cerealia Facula.

    On Ceres’ surface, salts bearing water quickly dehydrate, within hundreds of years. But Dawn’s measurements show they still have water, so the fluids must have reached the surface very recently.

    This is evidence both for the presence of liquid below the region of Occator crater and ongoing transfer of material from the deep interior to the surface.

    The researchers found two main pathways that allow liquids to reach the surface.

    “For the large deposit at Cerealia Facula, the bulk of the salts were supplied from a slushy area just beneath the surface that was melted by the heat of the impact that formed the crater about 20 million years ago,” said Dawn principal investigator Dr. Carol Raymond.

    “The impact heat subsided after a few million years; however, the impact also created large fractures that could reach the deep, long-lived reservoir, allowing brine to continue percolating to the surface.”

    Dawn captured pictures in visible and infrared wavelengths, which were combined to create this false-color view of a region in 92-km- (57-mile-) wide Occator crater on the dwarf planet Ceres. Recently exposed brine in the center of the crater was pushed up from a deep reservoir below Ceres’ crust. In this view, it appears reddish. In the foreground, is Cerealia Facula, a 15-km- (9-mile-) wide region with a composition dominated by salts. The central dome, Cerealia Tholus, is about 3 km (1.9 miles) across at its base and 340 m (1,100 feet) tall. The dome is inside a central depression about 900 m (3,000 feet) deep. The area depicted in this scene is about 2.1 km (1.3 miles) wide in the foreground, about 11 km (7 miles) wide across the dome, and 56 km (35 miles) wide in the background, where the crater rim rises against the black sky. The distance from the near point (at the bottom) to the far point (at the top) is about 52 km (32 miles). Image credit: NASA / JPL-Caltech / UCLA / MPS / DLR / IDA.

    Occator Crater on the dwarf planet Ceres

    Scientists are confident there's a deep brine reservoir under Occator crater.(NASA: JPL)

    In the Solar System, icy geologic activity happens mainly on icy moons, where it is driven by their gravitational interactions with their planets.

    But that’s not the case with the movement of brines to the surface of Ceres, suggesting that other large ice-rich bodies that are not moons could also be active.

    Some evidence of recent liquids in Occator crater comes from the bright deposits, but other clues come from an assortment of interesting conical hills reminiscent of Earth’s pingos — small ice mountains in polar regions formed by frozen pressurized groundwater.

    Such features have been spotted on Mars, but the discovery of them on Ceres marks the first time they’ve been observed on a dwarf planet.

    On a larger scale, the Dawn scientists were able to map the density of Ceres’ crust structure as a function of depth — a first for an ice-rich planetary body.

    Using gravity measurements, they found Ceres’ crustal density increases significantly with depth, way beyond the simple effect of pressure.

    The authors inferred that at the same time Ceres’ reservoir is freezing, salt and mud are incorporating into the lower part of the crust.

    • The findings were published in a series of papers in the journals Nature AstronomyNature Geoscience and Nature Communications.

    Heavy Rains Filled Lakes and Rivers on Early Mars, New Research Suggests

    Planetary researchers from the University of Texas at Austin and NASA’s Marshall Space Flight Center have used dry paleolakes and riverbeds to determine how much precipitation was present on Mars 3.5-4 billion years ago.

    The climate of the ancient Mars is something of an enigma to scientists. To geologists, the existence of riverbeds and paleolakes paints a picture of a planet with significant rainfall or snowmelt.

    But planetary scientists who specialize in computer climate models have been unable to reproduce an ancient climate with large amounts of liquid water present for long enough to account for the observed geology.

    “This is extremely important because 3.5 to 4 billion years ago Mars was covered with water,” said study lead author Dr. Gaia Stucky de Quay, a postdoctoral researcher in the Jackson School of Geosciences and the Center for Planetary Systems Habitability at the University of Texas at Austin.

    “It had lots of rain or snowmelt to fill those channels and lakes.”

    “Now it’s completely dry. We’re trying to understand how much water was there and where did it all go.”

    In the study, Dr. Stucky de Quay and colleagues found that precipitation must have been between 4 to 159 m (13-520 feet) in a single episode to fill the Martian lakes and, in some cases, provide enough water to overflow and breach the lake basins.

    “Although the range is large, it can be used to help understand which climate models are accurate,” Dr. Stucky de Quay said.

    “Climate models have trouble accounting for that amount of liquid water at that time. It’s like, liquid water is not possible, but it happened. This is the knowledge gap that our work is trying to fill in.”

    The scientists looked at 96 open-basin and closed-basin lakes and their watersheds, all thought to have formed between 3.5 billion and 4 billion years ago.

    Using satellite images and topography, they measured lake and watershed areas, and lake volumes, and accounted for potential evaporation to figure out how much water was needed to fill the lakes.

    By looking at ancient closed and open lakes, and the river valleys that fed them, they were able to determine a minimum and maximum precipitation.

    In 13 cases, the authors discovered coupled basins — containing one closed and one open basin that were fed by the same river valleys — which offered key evidence of both maximum and minimum precipitation in one single event.

    “Our study takes previously identified closed and open lake basins, but applies a clever new approach to constrain how much precipitation these lakes experienced,” said study co-author Dr. Tim Goudge, also from the Jackson School of Geosciences and the Center for Planetary Systems Habitability at the University of Texas at Austin.

    “Not only do these results help us to refine our understanding of the ancient Mars climate, but they also will be a great resource for putting results from NASA’s Mars 2020 Perseverance rover into a more global context.”

    • paper on the findings was published online in the journal Geology.

    95 new cool brown dwarfs in the sun’s neighborhood

    A group of citizen scientists working with a NASA citizen science project called Backyard Worlds: Planet 9 has discovered 95 new brown dwarfs in the sun’s nearby neighborhood.

They’re not massive enough to ignite thermonuclear fusion reactions in their interiors, and so shine as stars do. Yet they’re too massive to be considered planets.

    Almost every week, astronomers announce new discoveries such as exoplanets found orbiting distant stars, asteroids whizzing past Earth, and faraway galaxies with their massive black holes blazing at the edge of the universe. On August 18, 2020, NASA announced yet another discovery – made by members of the public assisting with a citizen science project – in this case of another 95 new cosmic neighbors – brown dwarfs – many within just a few dozen light-years of our solar system.

    • The findings are currently pending publication in The Astrophysical Journal.

    These citizen scientists helped to find the brown dwarfs through a NASA-funded project called Backyard Worlds: Planet 9. Like other such projects, this one is a collaboration between scientists and volunteers. It relies on data – lots of data – from various sources, including NASA’s Near-Earth Object Wide-Field Infrared Survey Explorer (NEOWISE) satellite, from NASA’s now-retired Spitzer Space Telescope and the National Science Foundation’s ground-based NOIRLab program, which involves five major obervatories. Sifting through the mountains of data collected by all these instruments is a huge task. That’s why citizen scientists are so helpful, said Aaron Meisner of NOIRLab. He co-founded Backyard Worlds, and he’s lead author of the new study:

    Vast modern datasets can unlock landmark discoveries, and it’s exciting that these could be spotted first by citizen scientists. These Backyard Worlds discoveries show that members of the public can play an important role in reshaping our scientific understanding of our solar neighborhood.

    Comparison of the typical masses of exoplanets, brown dwarfs and stars.

    Jackie Faherty of the American Museum of Natural History in New York said:

    This paper is evidence that the solar neighborhood is still uncharted territory and citizen scientists are excellent astronomical cartographers. Mapping the coldest brown dwarfs down to the lowest masses gives us key insights into the low-mass star-formation process while providing a target list for detailed studies of the atmospheres of Jupiter analogs.

    Brown dwarfs are fascinating objects that are too small and not massive enough to be stars, but too large and too massive to be considered planets. Some brown dwarfs can have temperatures in the thousands of degrees, but that’s not enough to fully “ignite” and become stars. Others are much colder, and many of the newly discovered ones are in this category. Some are colder than the boiling point of water, while others are actually have temperatures close to that of Earth. There is also evidence that, just like gas giant and ice giant planets, brown dwarfs can have very stormy atmospheres. The brown dwarf Luhman 16A may look a lot like Jupiter.

    Astronomer Aaron Meisner of NOIRLab. He is lead author on a citizen-science effort that led to the discovery of 95 new brown dwarf neighbors.

    If these brown dwarfs are so relatively close to us, why weren’t they discovered until now?

    The answer is that, since they’re relatively cool objects, they shine only faintly in visible light. They can also be seen in infrared light, but because of their cool temperatures, they’re faint in infrared as well.

    These new brown dwarfs are a missing link in the types of brown dwarfs known to exist, these scientists said. By learning more about them, they said they can learn more about how these objects form, and how they relate to other stars and planets in our sun’s neighborhood.

    Some brown dwarfs are cold enough to have water vapor clouds, similar to earthly clouds. There is evidence for this on the coldest known brown dwarf, WISE 0855, which was discovered in 2014 and is only about seven light-years away. With a temperature of minus 10 degrees Fahrenheit, or minus 23 degrees Celsius, some scientists thought it might actually be a rogue planet, floating freely in space between stars. The new discoveries now help to put WISE 0855 in the context of other cool brown dwarfs. According to astrophysicist Marc Kuchner, principal investigator of Backyard Worlds: Planet 9:

    Our new discoveries help connect the dots between 0855 and the other known brown dwarfs.

    And just how did the citizen scientists find the new brown dwarfs?

    The volunteers – over 100,000 of them – were approached by Backyard Worlds: Planet 9 to examine telescopic images consisting of trillions of pixels. Ultimately, 20 different citizen scientists from 10 countries became coauthors of the new study. They used sky maps produced from observations by WISE and NEOWISE and scoured additional archival datasets, such as those from the Nicholas U. Mayall Telescope at Kitt Peak National Observatory and Víctor Blanco 4-m Telescope at Cerro Tololo Inter-American Observatory (CTIO), both programs of NOIRLab. As one citizen scientist, Les Hamlet in Springfield, Missouri, said:

    Being that this will be the first scientific paper that I’m a coauthor on, its publication will definitely be the highlight of working with Backyard Worlds so far. Also, being connected in some way with the now-retired Spitzer Space Telescope through this paper is kind of special to me.

    These new brown dwarfs are just the latest to be discovered; Backyard Worlds: Planet 9 has previously found over 1,500 such cool worlds.

    So … what’s next?

    The Vera C. Rubin Observatory in Chile will soon image the entire southern hemispheric sky over 10 years, which should be yield many more cool brown dwarfs, among other discoveries. The upcoming James Webb Space Telescope (JWST) will be able to study some of these brown dwarfs more closely to find more clues as to how they form as well as other planet and atmospheres.

    Brown dwarfs are enigmatic worlds, and scientists are now starting to learn how they came to be, in their cosmic place between planets and stars.

    Almost 100 Brown Dwarfs Near Our Sun Have Been Recently Discovered

    According to a new study, citizen scientists have recently discovered nearly 100 brown dwarfs located fairly close to our sun. Several members of the public, which includes volunteers as well as professional scientists, were part of a citizen science project that was funded by NASA and called Backyard Worlds: Planet 9.

    During the project, over 100,000 citizen scientists analyzed data from NASA’s Near-Earth Object Wide-Field Infrared Survey Explorer (or NEOWISE) satellite as well as other data that was gathered by WISE between 2010 and 2011 in addition to information collected from the Spitzer Space Telescope and the National Science Foundation’s NOIRLab.

    They were able to locate 95 brown dwarfs which are space objects that are too small to be stars but too big to be planets. And they are relatively close to our sun with some of them being just a few dozen light-years away.

    Even though they are called brown dwarfs, they are actually orange/red or magenta in color. While some brown dwarfs can reach temperatures as hot as thousands of degrees Fahrenheit, they can also be cooler than the degree at which water boils, and some have temperatures pretty close to Earth which would allow them to have water clouds.

    The coldest brown dwarf ever found is called WISE 0855 and it was discovered in 2014. It has temperatures of around minus 10 degrees Fahrenheit (minus 23 degrees Celsius) which is by far the coldest brown dwarf that has been detected. In fact, it is so cold that some experts questioned whether it was instead a rogue exoplanet.

    It’s quite exciting to think that citizen scientists made such a significant discovery. “These Backyard Worlds discoveries show that members of the public can play an important role in reshaping our scientific understanding of our solar neighborhood,” said Aaron Meisner, who is an assistant scientist at NSF’s NOIRLab and the lead author of the study.

    Jackie Faherty from the American Museum of Natural History in New York and who is a co-author of the study, weighed in by stating, “This paper is evidence that the solar neighborhood is still uncharted territory and citizen scientists are excellent astronomical cartographers,” adding, “Mapping the coldest brown dwarfs down to the lowest masses gives us key insights into the low-mass star-formation process while providing a target list for detailed studies of the atmospheres of Jupiter analogs.”

    In total, volunteers for Backyard Worlds have so far detected over 1,500 cold worlds pretty close to our sun and the newly discovered 95 brown dwarfs were the most ever found through a citizen science project. Many more are probably just waiting to be found and the James Webb Space Telescope will surely help with the findings when it is launched next year.

    Unknown flashing object over Cleveland, Ohio 19-Aug-2020

    This bright UFO was seen and recorded in the sky above Cleveland, OH on August 19, 2020.

    Witness report: 

    On 08/19/20 at approximately 10:00 hours I was assigned to assist with traffic in downtown Cleveland. There were 4 other parties assigned to the intersection of E.9th & Bolivar to repair telephone lines. During our time at the intersection I was discussing the buildings surrounding area. We began discussing the cable that was stabilizing a communication tower and the insulator in the middle which we thought was odd. In the video you can see the insulator, which can be mistaken for a hovering object. At 10:23 hours I noticed an object fly out from behind one of the buildings. The crew I was working with had also noticed it. I took out my phone and attempted to capture video of the object. In the video, we can all be heard acknowledging the object. The object appeared to have an erratic flight path. It flew to my left and flashed a few times and then moved to my right and flashed a few times then shot off into the sky. I believe I found one view of it. As it was flashing and moving so quickly it was almost impossible to capture.

    Back to Possible Alien Spaceship for ‘Oumuamua

    It was a strange interstellar comet, it was a stranger spaceship, it was an interstellar asteroid, it was something else, and the latest — it’s a frozen hydrogen-sicle. And now, the cigar-shaped unknown space object from another solar system is back to being a spaceship … or at least a piece of alien technology. That’s the latest from two leading astrophysicists who have been watching and commenting on ‘Oumuamua ever since it showed up unannounced in 2017 and has been inspiring debates, exploration suggestions and occasional concern ever since.

    “The first interstellar object observed in our solar system, 1I/2017 U1 (‘Oumuamua), exhibited a number of peculiar properties, including extreme elongation and acceleration excess. Recently, Seligman & Laughlin proposed that the object was made out of molecular hydrogen (H2) ice. The question is whether H2 objects could survive their travel from the birth sites to the solar system.”

    Like this, only hyrdrogen?

    Avi Loeb, a Harvard astrophysicist, and Thiem Hoang, an astrophysicist at the Korea Astronomy and Space Science Institute, sprang into action as soon as astrophysicists Darryl Seligman, University of Chicago, and Greg Laughlin, Yale University, released their research paper in May 2020 proposing that ‘Oumuamua was formed in a giant molecular cloud (GMC) and is composed of molecular hydrogen ice – a giant cigar-shaped interstellar hydrogen iceberg. Seligman and Laughlin tied their theory to the idea that outgassing or evaporating hydrogen ice wouldn’t be visible from Earth — explaining the mystery of how ‘Oumuamua could be a comet if it didn’t have a tail, especially when it accelerated out of the solar system.

    “Assuming that H2 objects could somehow form in the densest regions of GMCs, we found that sublimation by collisional heating inside the GMC would destroy the objects before their escape into the ISM [interstellar medium]. We also studied various destruction mechanisms of H2 ice in the ISM. In particular, we found that H2 objects are heated by the average interstellar radiation, so that they cannot survive beyond a sublimation time of tsub ~ 10 Myr for R = 300 m (see Figure 1). Only H2 objects larger than 5 km could survive.”

    “Not so fast!” said Loeb and Hoang. In their response, published in The Astrophysical Journal Letters, they point out that the closest GMC is too far away for a hydrogen iceberg to survive the trip (due to the heat generated by cosmic collisions) and would probably not even survive an exit from a GNC. Loeb admits that, while this knocks ‘hydrogen iceberg’ off the “What’ is ‘Oumuamua?” list, we still don’t know for certain what it is. Fortunately, the Vera C. Rubin Observatory (VRO) is scheduled to become operational next year and he believes it will detect “one ‘Oumuamua-like object per month.” If they can’t figure out what it is with that kind of data, they need to turn in their astrophysicist club membership cards.

    ‘Oumuamua as alien technology disguised in a crust of space debris – proposed by Loeb in 2019 – was never disproved, just pushed down on the list of possibilities. With hydrogen iceberg joining the “Nope” list, it can move up again until the VRO collects more data or a human spaceship launched in time to catch ‘Oumuamua before it leaves the solar system.

    Place your bets on your favorite now.

    Hey guys, hope you all are having a great weekend. I'm just chilling at my computer and found a few things that seem significant to me and hopefully it will be significant to you too. 

    I found a structure on Mars. There is a window in it, even a doorway if you add much more light, but the door is only about 15% visible. Near the structure is a face wearing a Aztec animal like mask. I've seen this before in faces on Mars, its nothing new. 


    The thing that made me excited was the white fungus seen growing under the rock. Its round and tube-like...a plant stemming out to find more space to grow. 


    People say its impossible to discover life or evidence of life on other planets...but its what I do on a daily basis. Everything seems impossible until you put forth a little effort into it.

    Drone caught Fastwalker speeding over Entre Ríos Province, Argentina

    Anew drone footage shows one of the mysterious fastwalkers flying through our skies without we seeing them with the naked eye. The drone camera accidentally recorded the fastwalker moving at an incredible speed over Villa Valle María, Entre Ríos Province, Argentina on August 22, 2020.

    The drone at that time was 400 meters high.and the video has been shot by Alan Gerstner in 1080p (Full HD) at 50 frames per second.
    “Fastwalker” is a term used by NORAD and branches of armed forces to describe unidentified aerial phenomena moving and/or changing directions at high speed far beyond what current aerospace technology is capable of.
    The fastwalker is marked with a yellow circle, in slow motion and in the last part of the video with zoom. The right image above has been edited and shows specific details of the fastwalker.

    Company will Task Satellites to Hunt UFOs

    This Company Will Point Satellites at Earth and Use them to Look for UFOs

    Hypergiant Industries has clients like NASA, Shell, and Booz Allen. It says it can use machine learning from satellite imagery to detect anomalies.

    Nearly 4,000 light-years away, there’s a star called VY Canis Majoris. It is, in a word, huge. It’s 270,000 times as bright as the Sun, and if you plunked it down in the middle of our solar system, it would burn Saturn.

    VY Canis Majoris is a hypergiant star. And perhaps it is no surprise that there’s a tech startup humbly eponymizing it: Hypergiant Industries, a company that aims, its website explains, to be “the guiding light that solves humanity’s most challenging problems.”

    The company uses AI in a few different industries: It’s developed the Disaster Mapping System, geospatial software that picks out the hardest-hit buildings after a natural disaster using satellite and drone images, available open-source through an AI platform called Modzy. It’s also created a prototype augmented reality helmet which can detect and classify objects, and offers night vision and thermal imaging in addition to regular seeing. And it’s built a fridge-sized bioreactor prototype that uses AI to regulate things like air flow, light, temperature, and pH so that algae can sequester carbon dioxide and turn it into materials for biofuel. Oh, and it’s built kinda boring workflow efficiency software for companies like GE and Shell, plus a “Virtual Bartender” for TGI Fridays.

    Hypergiant was founded just two years ago, in 2018, but the company has already worked with the likes of Booz Allen Hamilton, Shell, NASA, the National Reconnaissance Office, and the Department of Homeland Security. The company spun up so quickly in part because it didn’t just build from scratch. It fused already-extant elements: buying image-analysis companies, investing in AI developers, and scooping up space technology, in the service of delivering on its slogan: “Tomorrowing today.”

    That all sounds pretty legit: Serious government agencies, serious firms, serious fortune, and Fortune 500. And that clout is probably part of why Hypergiant’s R&D division can, without risking too much blowback, now take a risk on something farther-out: UFO research. This may actually be more grounded, and profitable, than it sounds.

    *

    Hypergiant was founded by CEO Ben Lamm, a serial entrepreneur who sold his previous companies to big names like Zynga and Accenture. This company, though, he intends to hang on to.

    Once Lamm decided he wanted to start Hypergiant, he said in an interview, he and his team started brainstorming where AI could still make a big difference. They settled on three main areas: infrastructure, like supply chains and logistics; defense; and space.

    On the list of those projects on the company’s website, though, the new UFO endeavor isn’t listed. The company’s website does list some projects as “redacted,” however.

    But Lamm does talk about UFOs, though he calls them UAP: Unidentified Aerial Phenomena. It’s the term insiders and the government have introduced to ditch the baggage that the decades-old “UFO” has amassed. If you look at the intersections Hypergiant’s three main interests, says Lamm, “UAPs are the X at the cross center.”

    He’s interested in finding out whether those UAP come from here, or out there. “The question of whether we’re alone in the universe is kind of like ‘Is the Earth flat?’” he says (“no” being the answer to both, in his mind).

    The US government has recently vocalized its interest in UFOs: the Navy has crafted new guidelines for soldiers to report sightings; Congresspeople have gotten classified briefings; officials speak of strange stuff in the sky as an imposing national-security threat.

    Notably, there’s no evidence that directly supports the interpretation that UFOs are of extraterrestrial origin. In fact, signs point in a different direction: the Navy has said that UAP sightings are on the rise “consistent with the wide proliferation and availability of inexpensive unmanned aerial systems,” which are just cheap drones. Military definitions of “UAP” include objects that are simply unauthorized, not necessarily unidentified.

    Lamm accepts that the phenomena might just be earthly technology, and he wants Hypergiant to help find whatever truth is out there.

    “If this is a brilliant lady and guy who build insane technology in a garage in Iowa, we should know about that,” he says. “Regardless of what the UAP is and whether it has a terrestrial origin or not, I think it’s important for people’s safety.”

    Hypergiant’s research trajectory homes in on exactly what UAP investigators have never nabbed: hard data collected in a systematic way. In this case, data largely from Earth-watching satellites.

    The company plans to scrutinize that data with software it’s developing called CONTACT: Contextually Organized Non Terrestrial Active Capture Tool. Although it’s still in early stages, it will, the company hopes, burrito together adapted versions of Hypergiant’s existing tools, like the Disaster Mapping System, and new ones, to parse orbital and aerial images in search of Anomalies.

    In its future final form, CONTACT will analyze 3-dimensional satellite data. Or ”volumetric” information, that reveals not just where a craft is in terms of its latitude, longitude, and altitude. CONTACT will spot the differences between satellite images and throw up a flag if, say, a mothership flies into a field of view at noon when it wasn’t there yesterday, and then determine whether it’s actually just a jet at a weird angle.

    For that task, the team is developing a neural network that can recognize known aircraft. “This is xyz helicopter,” says Lamm. “This is xyz Raptor. This is a Boeing 737.” Those go in the digital trash.

    To help train these aircraft-spotting algorithms, Hypergiant is creating a siphon that sucks up public information about creepy sky sightings that people think are unidentified and tags them with locations and times. The software will then dive into satellite and drone archives, gather images of the right regions and hours, and use computer vision to find fliers. After comparing whatever it finds against known airline flight paths, and screening out all the Boeings, the researchers will use what’s left as training data, to help AI identify UAP in future observations.

    Hypergiant positions CONTACT as a way to investigate cosmic mysteries: to toss out terrestrial knowns in search of possible extraterrestrial unknowns. But the tool would be equally adept at identifying terrestrial unknowns: experimental drones, and advanced military aircraft tests, for example. Because of this, Lamm believes that CONTACT would be of keen interest to officials with extremely earthly concerns. “It’s highly valuable to big defense contractors, the Air Force, radar operators,” says Lamm.

    If things go well, which they often don’t in space, Hypergiant engineers will start gathering their own data. On a rocket scheduled to launch in March, Hypergiant will send up its first instrument that can take 3-D observations, in the form of a payload piggybacked on a larger satellite. Data should start to rain down in April or May.

    Assuming that works, the first satellite of Lamm’s 30+ orbiter constellation will go up in the fall, on the Cygnus NG-14 and SpaceX SpX-21 missions. And then, presumably, the other 29 or so. And then, perhaps, the startup will data that will illuminate what we talk about when we talk about UAP, UFOs, or whatever acronyms someone comes up with later. To see whether or not all of that happens, we’ll have to wait till today becomes tomorrow.

    Has the Biblical Moses Been Identified in Secular Egyptian Records?

    Moses was a prophet and a leader according to Abrahamic religions, but many scholars view him as a legendary figure rather than a real historic person. They do concede that a Moses-like figure could have existed in history, so is it possible to track this person down through historic records? It is the view of this writer that this is very possible and that in fact the Moses figure can be traced as that of the primary confidant of none other than Egyptian pharaoh Hatshepsut. The trail begins with Th Exodus.

    The Exodus and Moses Birth

    What is the date of the Exodus ? To find Moses in the Egyptian records, the first requirement is to fix the date of the Exodus of the Hebrews from Egypt.

    If we use the Bible as our primary source, we know that this occurred during the ‘ New Kingdom ’ period of Egypt, when the powerful Egyptian families of the south reasserted themselves and drove out the Hyksos invaders , who had been entrenched in the power centers of northern Egypt for over 100 years.

    The Hyksos’ stay in Egypt is known in history as the ‘Second Intermediate Period’. However, there is a difference of opinion among biblical scholars as to when, during the New Kingdom, the Exodus occurred. So, can we find anything to help us pin it down?

    If one accepts the biblical dating of Solomon’s time , we know that he started building his famous temple in 960 BC, and the text of 1 Kings 6 v1 states that this was 480 years since the Exodus .
    Thus, we can fix a date for the Exodus of 1440 BC, when Moses was 80 years old. This would mean that he was born around 1520 BC and is an adult in the court between 1500 and 1480 BC.

    Where Does the Name Moses Come From?

    1500 – 1480 BC is the time of the pharaoh Queen Hatshepsut, and she had a close confidant, described by the well-known Egyptologist Joyce Tyldesley in her book on Hatshepsut, as the ‘Greatest of the Great’.

    The father of Hatshepsut was Thutmose l , and his name means ‘son of Thoth’, the god of wisdom, ‘mose’ meaning ‘son’. This is a common use of the word ‘mose’ as in ‘Ra meeses’, son of the sun god Ra, etc.

    The biblical text tells us that it was the pharaoh’s daughter who named Moses. Exodus 2 v 10 states that, “she called him Moses because she said, ‘I drew him out of the water’”.

    The finding of Moses.

    (Light snow / Public Domain )

    But we will not find a Prince Moses in the court in Egypt because another bible reference, Hebrews 11 v 24, states that “ Moses, when he had grown up, refused to be known as the son of Pharaoh’s daughter”.

    Instead, we find that the close confidant of the queen is a man called ‘ Senenmut’. This appears to be a unique name, and one of its meanings is ‘mother’s brother’. Hatshepsut was born in the early 1530s, so they were close in age, so such a name makes sense.

    Why Would the Royal Heiress Adopt a Slave Child?

    If Hatshepsut is the woman who rescued and adopted Moses, what would make a woman of such high standing adopt a slave child? After her mother, Hatshepsut was the highest woman in the land, and such a woman would not consider saving the life of a slave child, let alone adopt him as her son.
    But when we look at the past, it is hard for us to remember that the people we are observing are just like us. They have thoughts and feelings like us, and Hatshepsut, at the time she found the abandoned baby in the basket, was a little girl, with the instincts to protect the helpless that we see so often in children. The text of Exodus 2 v 6 says “she saw the child, he was crying, and she took pity on him”.

    Hatshepsut knew that he was a Hebrew child, as the rest of the verse tells us. But she was too young to look ahead and understand the enormity of her action. Almost immediately she must have formed an attachment to him, and as he grew the attachment grew, and her loyalty to him would alter the course of her life.

    So, What Do We Know of Hatshepsut?

    We know that Hatshepsut married her brother, Thutmose II, becoming his ‘Great Royal Wife’, his principal queen. She bears him two daughters but no sons and, following his death after a reign of only 13 years, his son by a harem woman is made the pharaoh, becoming Thutmose III .

    This new pharaoh is an infant and Hatshepsut is made regent. She is effectively the ruler of the land, holding all the power already, and so it seems odd to Egyptologists that after just two years she makes herself pharaoh.

    Did she have ambitions to put her adopted son on the throne? This she could do if she were pharaoh, but not if she were only regent. She reigns as the senior pharaoh, jointly with Thutmose III for 22 successful years, until her death.

    She rules the country well. She sets up trading expeditions with the lands south of Egypt. She keeps a firm grip on Nubia, Egypt’s southern neighbor from which vast resources are acquired, including gold, cattle, slaves, and soldiers. She carries out extensive building works, both in Waset, the ancient name for Luxor, and around the country.

    (Pharos / Public Domain )

    She extends the Temple of Amun in Waset, erecting 4 huge obelisks in his honor, two of which are still there, one still standing. It bears engravings as clear as they were when it was erected 3,500 years ago, reading – “Raised for the glory my father Amun that I may be given life”. She builds a magnificent mortuary temple for herself , where the gods are honored, known as the Temple of Deir el Bahri, which still stands and is visited by thousands of tourists every year.

    What Happened to Hatshepsut’s Memory After Her Death?

    Hatshepsut ruled her country well and was buried honorably, probably with her father Thutmose l in tomb KV 20, a tomb she had built for a double burial.

    After the death of his stepmother, Thutmose III continued his long reign of over 50 years, spending much of that time campaigning in the Levant, defeating the power of the Hittites to the northwest and the Mittani to the northeast and bringing the wealthy city states of Canaan firmly under Egyptian control. He is known as the ‘Napoleon of Egypt’ for his success as a military man.

    But 30 years after her death, all records of Hatshepsut came under attack. Her statues were removed from the temples, smashed and buried in a pit, and her reliefs were excised from the walls of the temples. In subsequent years, Hatshepsut’s name was omitted from the King Lists , a thing done to no other pharaoh except the great heretic pharaoh Akenaten but not to the one previous female pharaoh Sobekneferu who reigned briefly at the end of the 12th Dynasty.

    Removing all record of Hatshepsut’s name was intended, by the Egyptians, as the ultimate punishment, known as ‘damnatio memoriae’. All records of a person removed from history as if they had never lived resulted in the death of their soul for eternity. This effectively removed Hatshepsut from Egyptian history until all memory of her and why she had been so hated was lost.

    She was forgotten for over 1,000 years, until vague references to her were found by the priest Manetho in 300 BC when he was asked by the Greeks in power at that time to search out and list the pharaohs of Egyptian history. He found references to a female pharaoh called Amensis, who was identified by later Egyptologists as Hatshepsut, and recorded her as the fifth pharaoh of the New Kingdom Dynasty, but nothing more was known of her.

    It was thought that Hatshepsut’s mummy had been lost, but it has recently been identified lying abandoned in the tomb of her royal nurse Sitre, tomb KV 60. It was identified by a tooth fragment known to belong to Hatshepsut, and the mummy appeared to have been left without ceremony, perhaps in haste to hide it from those who would have destroyed it. The Egyptians believed that the preservation of the body was essential to survival in the afterlife, hence the lengths they went to, to preserve them. It was the ultimate punishment to destroy a person’s body.

    So, Who Would Have Tried to Remove Hatshepsut From History?

    The action against Hatshepsut’s (and Senemut’s) memory occurs either late in the reign of Thutmose III, when his son Amenhotep II was sharing the throne, or after Thutmose’s death, when Amenhotep II was reigning alone. It seems therefore to be Amenhotep II who is responsible for this destruction.

    He would be at the correct time to see the return of Moses demanding the release of the Hebrew slaves. The story of the Exodus describes great hardship for Egypt, and one can understand Amenhotep’s fury against both Hatshepsut and Senenmut and wishing to destroy their memory. Being wiped out of history for the Egyptians was tantamount to eternal damnation.

    When Were Hatshepsut’s Statues Discovered and What Did They Reveal?

    During the 1800s, wealthy gentlemen such as James Breasted went to Egypt specifically with the hope of finding evidence to prove the biblical record . These men effectively established the science of Egyptology.

    But at that time, the statues of Hatshepsut still lay buried in the pit where they were thrown 30 years after her death. They remained there undiscovered until found by Herbert Winlock an American Egyptologist employed by the Metropolitan Museum of Art in Boston, United States in 1927, by which time the world at large was no longer interested in trying to prove the Bible.
    But not only was a hoard of statues of Hatshepsut discovered just east of the first court of her mortuary temple at Deir el Bahri. Another pit was found, containing over 20 hard stone statues of Senenmut, a huge number for a non-royal. In fact, to date, 26 hard stone statues of Senenmut have been identified which causes Egyptologists to wonder what was it about this man that he was given such status.

    What Do We Know About Senenmut?

    The first thing to confront us when looking at the records of Senenmut are the many beautiful statues of him as a young lad holding Hatshepsut’s elder daughter, the Princess Neferure . She is there wrapped in his cloak as a baby as he sits on the ground.

    He is holding her in his arms the way a woman would hold a child. In some examples he sits on a chair holding her on his lap. Some are of him standing holding Neferure as a toddler, but altogether they show a level of intimacy between the two of them, as we would have in photos taken of our children together.

    He is said to be the tutor to Neferure, but statues of a royal child being held like this had never been made before this date. And this is breaking protocol because a non-royal is not allowed to touch a royal child in this way.

    And we know that Senenmut is not royal because he names his parents in one of his tombs, and they have no titles at all, showing that they are of humble origin. But the extraordinary thing about Senenmut is that he is treated as a royal.

    He has two beautiful tombs built for himself, one, TT 353 has the oldest known star chart, a work of great expertise, on the ceiling. And this tomb is actually within the sacred precinct of Hatshepsut’s mortuary temple. This is a sacred space and to have Senenmut’s tomb in such a place, sacred in itself, but also the personal space of the pharaoh, shows a degree of closeness between them that is shocking, unless there is an explanation for it.

    The other tomb TT 71 has decorations described by the Egyptologist Peter Dorman in the book ‘ Hatshepsut from Queen to Pharaoh’ , page 131 as being clearly done “by artists from the royal ateliers”. Dorman also dismisses the suggestion that Senenmut may have been Hatshepsut’s lover.
    In this tomb TT 71, a sarcophagus belonging to Senenmut was found. It is made of quartzite, a material only allowed to be used by the royals.

    We know that Moses neither dies nor is buried in Egypt. And Senenmut is not buried in either of his tombs but disappears from Egyptian records.

    Besides the statues of Senenmut holding the infant princess, there are many statues made of him making offerings to the gods. These statues were made to stand in the presence of the gods, and again, it is not permitted for a non-royal to enter the presence of the gods; having your statue there was the equivalent of you being there in person.

    Here again he is treated as a royal. And all these statues are of a very young man, so it must be Hatshepsut who ordered these statues to be made. To be in the presence of the gods was a very favored position, because you would receive the continual blessings of the gods.

    We also find a number of reliefs carved in the most sacred space of all in the Deir el Bahri Temple, in the sanctuary of Amun itself. One is even carved in the back wall of the sanctuary, where the ceremonial boat which carried the idol of Amun was placed overnight before its return journey to Waset. For the images of a common citizen to be placed in such a sacred space, breaks every rule in the book, but Hatshepsut must have done this, and done it because Senenmut was the son she had adopted, and she was ambitious for him to rise high in Egypt.

    During the course of his years at the court of Hatshepsut, Senenmut is acknowledged by experts in Egyptology, to have held many of the highest titles in the land, showing that he truly was the ‘Greatest of the Great’, in Hatshepsut’s court.

    Senemut’s high standing in the court during the reign of Hatshepsut, coupled with him being wiped from the Egyptian historical narrative, and the correlation between the biblical and Egyptian dating, would suggest therefore that he was the person we know from the Bible as Moses.

    Having discovered the story of Hatshepsut and Senenmut, I decided to present it as an historical novel. It was published in October 2018 by Mirador. It is called ‘ The King and her children’ and is available from Waterstones and Amazon.

    Violent thunderstorms on Jupiter may form 'mushballs' that fall from the sky

    Thunderstorms on Jupiter are so strong that ammonia-rich hail known as "mushballs" may fall from the sky.

    New observations from NASA's Juno spacecraft at the gas giant planet could have implications for our understanding of giant planet atmospheres in general, which are largely made of gas and are subject to much higher pressures than what we are familiar with on Earth.

    These observations also suggest that Jupiter has "shallow lightning", which happens in clouds containing ammonia and water. That's quite different than on Earth, where lightning originates in water clouds, according to a NASA statement.

    "Juno's close flybys of the cloud tops allowed us to see something surprising – smaller, shallower flashes – originating at much higher altitudes in Jupiter's atmosphere than previously assumed possible," Heidi Becker, Juno's radiation monitoring investigation lead at NASA's Jet Propulsion Laboratory in California, said in the same statement. Becker is also lead author of a new paper in Nature, one of three new studies describing Juno's work.

    Thunderstorms on Jupiter and Earth do have one thing in common: these natural phenomena move water about in the atmospheres of both planets. When NASA's Voyager spacecraft first spotted lightning at Jupiter in 1979, it was thought that both planets had similar kinds of lightning.

    This infographic shows the evolutionary process of “shallow lightning” and "mushballs" on Jupiter.

     Voyager spotted lightning in Jupiter's cloud tops, which suggested the phenomenon originated in deep water clouds. Juno's new observations of nighttime flashes on Jupiter, however, reveal a more subtle story.

    "At these altitudes, the ammonia acts like an antifreeze, lowering the melting point of water ice and allowing the formation of a cloud with ammonia-water liquid," Becker added in the same statement. "In this new state, falling droplets of ammonia-water liquid can collide with the upgoing water-ice crystals and electrify the clouds. This was a big surprise, as ammonia-water clouds do not exist on Earth."

    The shallow lightning may also show why ammonia appears to be missing (or depleted) from Jupiter's atmosphere, and why ammonia appears in different concentrations in Jupiter's atmosphere.

    "Previously, scientists realized there were small pockets of missing ammonia, but no one realized how deep these pockets went or that they covered most of Jupiter," Scott Bolton, Juno's principal investigator at the Southwest Research Institute in San Antonio, said in the same statement.

    "We were struggling to explain the ammonia depletion with ammonia-water rain alone," Bolton added, "but the rain couldn't go deep enough to match the observations. I realized a solid, like a hailstone, might go deeper and take up more ammonia. When Heidi discovered shallow lightning, we realized we had evidence that ammonia mixes with water high in the atmosphere, and thus the lightning was a key piece of the puzzle."

    The "mushballs" and depleted ammonia are described further in work published in the Journal of Geophysical Research: Planets in two parts, available here and here. When ice crystals combine with ammonia (a plentiful substance in Jupiter's atmosphere), the ammonia creates an "antifreeze" effect and changes the ammonia from ice to liquid. 

    When the mushballs fall into Jupiter's lower atmosphere, they drag down ammonia and water with them before eventually evaporating in the warmer temperatures. "That explains why we don't see much of it in these places with Juno's microwave radiometer," Tristan Guillot, a Juno co-investigator from the University of Côte d'Azur in Nice, France, and lead author of the two-part paper on ammonia and the mushballs, said in the NASA statement

    "As it turned out, the ammonia isn't actually missing; it is just transported down while in disguise, having cloaked itself by mixing with water," Bolton added. "The solution is very simple and elegant with this theory: When the water and ammonia are in a liquid state, they are invisible to us until they reach a depth where they evaporate – and that is quite deep."

    Juno arrived at Jupiter almost exactly four years ago, on July 4, 2016, to better understand the origin and evolution of the planet. Juno's findings not only inform our understanding of solar system planets but also gas giant exoplanets, especially those of a similar size and formation history to planets in our solar system.

    Space roar: NASA detected the loudest sound in the universe, but what is it?

    In space, nobody can hear you scream, but with the right equipment, it is possible to detect a roar. That's what scientists discovered back in 2006 when they began to look for distant signals in the universe using a complex instrument fixed to a huge balloon that was sent to space. The instrument was able to pick up radio waves from the heat of distant stars, but what came through that year was nothing short of astounding.

    As the instrument listened from a height of about 23 miles (37 kilometers), it picked up a signal that was six-times louder than expected by cosmologists. Because it was too loud to be early stars and far greater than the predicted combined radio emission from distant galaxies, the powerful signal caused great puzzlement. And scientists still don't know what is causing it, even today. What's more, it could hamper efforts to search for signals from the first stars that formed after the Big Bang.

    The instrument that detected the mysterious roaring signal was the Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission (ARCADE), which NASA built to extend the study of the cosmic microwave background spectrum at lower frequencies. 

    The mission's science goals — as ARCADE floated high above Earth's atmosphere, free of interference from our planet — were to find heat from the first generation of stars, search for particle physics relics from the Big Bang and observe the formation of the first stars and galaxies. It accomplished these goals by scanning 7% of the night sky for radio signals, since distant light becomes radio waves as it loses energy over distance.

    NASA's sound from space

    ARCADE was able to make "absolutely calibrated zero-level" measurements, which means it was measuring the actual brightness of something in real physical terms rather than relative terms. This was different from typical radio telescopes, which observe and contrast two points in the sky. By looking at all of the "light" and comparing it to a blackbody source, ARCADE was able to see the combination of many dim sources. It was then that the intensity of one particular signal became apparent, albeit over many months.

    "While it might make a good movie to see us surprised when we see the light meter pop over to a value six-times what was expected, we actually spent years getting ready for our balloon flight and a very busy night taking data," said NASA scientist Dale J. Fixsen. "It then took months of data analysis to first separate instrumental effects from the signal and then to separate galactic radiation from the signal. So the surprise was gradually revealed over months." That said, the impact was still huge.

    Since then, scientists have looked to see where the radiation is coming from while looking to describe the properties of the signal. The latter became apparent rather quickly. 

    "It's a diffuse signal coming from all directions, so it is not caused by any one single object," said Al Kogut, who headed the ARCADE team at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "The signal also has a frequency spectrum, or 'color,' that is similar to radio emission from our own Milky Way galaxy."

    Scientists call the signal "radio synchrotron background" — background being an emission from many individual sources and blending together into a diffuse glow. But because the "space roar" is caused by synchrotron radiation, a type of emission from high-energy charged particles in magnetic fields, and because every source has the same characteristic spectrum, pinpointing the origin of this intense signal is difficult.

    "It has been known since the late 1960s that the combined radio emission from distant galaxies should form a diffuse radio background coming from all directions," Kogut told All About Space in an email. "The space roar is similar to this expected signal, but there doesn't seem to be six-times more galaxies in the distant universe to make up the difference, which could point to something new and exciting as the source."

    Is the space roar coming from the Milky Way?

    Whether or not this source is inside or outside the Milky Way is under debate.

    "There are good arguments why it cannot be coming from within the Milky Way, and good arguments for why it cannot be coming from outside the galaxy," Kogut said.

    One reason it probably isn't coming from within our galaxy is because the roar doesn't seem to follow the spatial distribution of Milky Way radio emission. But nobody is saying for certain that the signal isn't from a source closer to home — only that the smart money is on it coming from elsewhere.

    "I wouldn't quite say that scientists have largely ruled out the possibility of the radio synchrotron background originating from our galaxy," said Jack Singal, an assistant professor of physics at the University of Richmond in Virginia, who recently led a workshop on the matter. "However, I would say that this explanation does seem to be less likely.

    "The primary reason is that it would make our galaxy completely unlike any similar spiral galaxy, which as far as we can tell do not exhibit the sort of giant, spherical, radio-emitting halo extending far beyond the galactic disk that would be required. There are other issues as well, such as that it would require a complete rethinking of our models of the galactic magnetic field."

    Fixsen agrees wholeheartedly. "In other spiral galaxies there is a close relation between the infrared and radio emission, even in small sections of these others," he said. "So, if it is from a halo around our galaxy, it would make the Milky Way a weird galaxy, while in most other respects it seems like a 'normal' spiral galaxy."

    For those reasons, experts think the signal is primarily extragalactic in origin. "It would make it the most interesting photon background in the sky at the moment because the source population is completely unknown," Singal said. But since the universe is so vast this doesn't exactly narrow things down that much, which is why scientists have been working hard to come up with multiple theories for the signal's source.

    American physicist David Brown, for example, said the space roar could be "the first great empirical success of M-theory," a broad mathematical framework encompassing string theory. "There might be a Fredkin-Wolfram automaton spread across multitudes of alternate universes, yielding recurrent physical time with endless repetitions of all possible physical events," Brown wrote on the FQXi Community blog. What this supposes is that the early universe had much more real matter than today, accounting for the powerful radio signal.

    The space roar could be "the first great empirical success of M-theory," a broad mathematical framework encompassing string theory.

    - Physicist David Brown

    But if that is too far out, there are other theories to get your teeth into. "Radio astronomers have looked at the sky and have identified a couple of types of synchrotron sources," Fixsen said. 

    Synchrotron radiation is easy to make, he said. "All you need is energetic particles and a magnetic field, and there are energetic particles everywhere, produced by supernovas, stellar winds, black holes, even OB stars," which are hot, massive stars of spectral type O or early-type B. "Intergalactic space seems to be filled with very hot gas, so if intergalactic magnetic fields were strong enough [stronger than predicted], they could generate smooth synchrotron radiation," he said.

    It is also known that synchrotron radiation is associated with star production. "This also generates infrared radiation, hence the close correlation," Fixsen said. "But perhaps the first stars generated synchrotron radiation yet, before metals were produced, they did not generate very much infrared radiation. Or perhaps there is some process that we haven't thought of yet."

    So what does this leave us with? "Possible sources include either diffuse large-scale mechanisms such as turbulently merging clusters of galaxies, or an entirely new class of heretofore unknown incredibly numerous individual sources of radio emission in the universe," Singal said. "But anything in that regard is highly speculative at the moment, and some suggestions that have been raised include annihilating dark matter, supernovae of the first generations of stars and many others."

    Some scientists have suggested gases in large clusters of galaxies could be the source, although it's unlikely ARCADE's instruments would have been able to detect radiation from any of them. Similarly, there is a chance that the signal was detected from the earliest stars or that it is originating from lots of otherwise dim radio galaxies, the accumulative effect of which is being picked up. But if this was the case then they'd have to be packed incredibly tightly, to the point that there is no gap between them, which appears unlikely.

    How the 13-year-old mystery will be solved 

    "Of course, there is also the possibility that there has been a coincidence of errors among ARCADE and the other measurements to date that have mismeasured the level of the radio synchrotron background," Singal said. "This does seem unlikely, given that these are very different instruments measuring in quite different frequency bands."

    Whatever the signal is, it's also causing issues when it comes to detecting other space objects. As NASA has pointed out in the past, the earliest stars are hidden behind the space roar, and that is making them more difficult to detect. It's as if the universe is giving with one hand and taking with another, but to have uncovered something so unusual is immensely exciting. When you're ruling out an origin from primordial stars and known radio sources such as gas in the outermost halo of our galaxy, it's a mystery any scientist would savour with relish.

    "Beyond that, I think we may need some brilliant new origin hypothesis that nobody has thought of yet."

    - Astrophysicist Jack Singal

    In order for scientists to finally resolve this 13-year conundrum, more research and evidence is sorely needed. As it stands, there is a debate over sending ARCADE back up given the advent of new technology, and given its precise set of instruments, immersed in more than 500 gallons of ultra-cold liquid helium to make them even more sensitive, there would certainly be no harm in doing so.

    But there are also new projects emerging which could help. "One of them will use the 300-foot [91 meter] radio telescope at Green Bank, West Virginia, to map the radio sky to higher precision than before," Kogut said. "Perhaps this will shed some light on the mystery."

    Singal certainly hopes so. He is working on the Green Bank Telescope project, making use of the largest clear-aperture radio telescope in the world to measure the level of the background as a primary, rather than ancillary goal. It will do this using a definitive, purpose-built, absolutely calibrated zero-level measurement taken at the megahertz (MHz) frequencies where the radio sky is brightest. (A megahertz is equal to a million hertz.)

    "This measurement is currently being developed by a team which I am on, utilizing custom instrumentation which will be mounted on the telescope," Singal explained. There is also going to be another measurement attempt, this one looking to measure or further limit the so-called "anisotropy," or variation of the radio synchrotron background, again at the MHz frequencies where it dominates.

    "That is not its absolute level, but rather the small differences from place to place in the sky," Singal said. "With some collaborators, I am trying a first attempt at that using the Low-Frequency Array [LOFAR] in The Netherlands. Both of these measurements in concert can help nail down whether the radio synchrotron background is primarily galactic or extragalactic in origin. Beyond that, I think we may need some brilliant new origin hypothesis that nobody has thought of yet."

    A deep, giant cloud disruption found on Venus

    Researchers have discovered a giant atmospheric wave-like phenomenon in Venus’ lower atmosphere, unlike anything else seen in the solar system. Evidence shows it has existed since at least 1983, but went completely undetected until now.

    Scientists have announced something new and unexpected: a giant atmospheric “wave” or disruption in Venus’ lower atmosphere. It’s unlike anything else seen in the solar system. The researchers say it has been rapidly moving at about 30 miles (50 km) above the planet’s surface for at least 35 years. It went completely undetected until now.

    • The amazing discovery is reported in a new peer-reviewed study, published May 27, 2020, in Geophysical Research Letters.

    Venus is the planet next-inward to the sun from Earth. It’s completely covered by thick clouds. These clouds are so dense that we can’t peer beneath them to view Venus’ surface. For this reason, the lower atmosphere and surface of Venus have remained largely mysterious. We know the clouds of Venus consist mostly of carbon dioxide, with droplets of sulphuric acid. Strong wind patterns have been observed before in the atmosphere of Venus in ultraviolet and infrared light.

    The new atmospheric feature – a giant wall of acidic clouds – is different from previous observations in part because it’s the first huge atmospheric wave found at the lower cloud level in Venus’ atmosphere, at altitudes between 29.5 and 35 miles (47.5 and 56.5 km). This wall of clouds is massive, extending as far as 4,700 miles (7,500 km) across the equator of Venus, from 30 degrees north to 40 degrees south.

    According to the researchers, it rotates around the planet in five days, at about 204 miles per hour (328 kph). It’s been doing that since at least 1983.

    The Japanese space agency JAXA’s Venus orbiter Akatsuki made the discovery. The phenomenon looked like an atmospheric wave, only much larger than what’s typically seen. It was found by Akatsuki as the spacecraft acquired detailed infrared images of Venus’ nightside, studying the mid and lower layers of the planet’s atmosphere.

    Pedro Machado – of the Institute of Astrophysics and Space Sciences, part of the University of Lisbon in Portugal – said in a statement:

    If this happened on Earth, this would be a frontal surface at the scale of the planet, and that’s incredible. Under the follow-up campaign, we went back to images I took in the infrared in 2012 with the Galileo National Telescope in the Canary Islands, and we found precisely the same disruption.

    The Institute of Astrophysics and Space Sciences has had a long-running research program studying Venus’ winds. It also contributed follow-up observations with NASA’s Infrared Telescope Facility in Hawaii, coordinated with the new observations from Akatsuki.

    Huge cloud patterns have been observed before in Venus’ atmosphere, such as the Y wave, a dark Y-shaped structure found in the upper atmosphere that covers nearly the whole planetary disk. It is only visible when observed in ultraviolet light. There is also a 6,200-mile-long (10,000-km-long) bow-shaped stationary wave, also in the upper clouds layers, thought to be caused by the planet’s huge mountain ranges.

    Meanwhile, in visible light, Venus’ dense atmosphere looks very bland.

    Finding this phenomenon in the lower atmosphere is interesting, not only because it wasn’t noticed before, but also because this region in the atmosphere of Venus is thought to be responsible for the planet’s hellish greenhouse effect. This effect causes the heat of the sun to be retained near Venus’ surface. It keeps the surface at a sizzling temperature of 869 degrees Fahrenheit (465 degrees Celsius), hot enough to melt lead. The dynamics of Venus’ atmosphere are still not well understood overall, so planetary-scale waves such as this might help scientists better understand how the planet’s surface and atmosphere interact.

    Javier Peralta, who led the new study, said:

    Since the disruption cannot be observed in the ultraviolet images sensing the top of the clouds at about 43-mile (70-km) height, confirming its wave nature is of critical importance. We would have finally found a wave transporting momentum and energy from the deep atmosphere and dissipating before arriving at the top of the clouds. It would therefore be depositing momentum precisely at the level where we observe the fastest winds of the so-called atmospheric super-rotation of Venus, whose mechanisms have been a long-time mystery.

    This newly discovered cloud front on Venus is essentially meteorological. Basically, we’re talking here about the weather on Venus. The feature appears to be unique; it’s never been seen before on any other planets in the solar system. It’s therefore difficult to know for certain what is happening, even though the researchers have devised computer simulations to try to mimic the cloud feature. The mechanisms that can create such a giant and long-lasting atmospheric wave are still unknown.

    One possibility is that this atmospheric disruption may be a physical manifestation of a type of Kelvin wave, a class of atmospheric gravity wave that shares some important common features with this disruption. Kelvin waves can maintain their shape over long periods of time, and in this case, propagate in the same direction as Venus’ super-rotating winds. Kelvin waves can also interact with other types of atmospheric waves, such as Rossby waves, which naturally occur as a result of the rotation of the planet. Like Kelvin waves, they can be seen in both atmospheres and oceans. On Venus, they may transport energy from the super-rotation of the atmosphere – where the atmosphere rotates faster than the planet itself – to the equator.

    The researchers looked at images of Venus going as far back as 1983. They were able to confirm the presence of the same features that were seen by Akatsuki. But how did this particular – and huge – wind formation go unnoticed for so long? According to Machado:

    … we needed access to a large, growing and scattered collection of images of Venus gathered in the recent decades with different telescopes.

    Finding such a large atmospheric phenomenon on Venus, after its being undetected for so long, was a big surprise for scientists. The discovery will help them learn more about the planet’s complex atmosphere and how it interacts with the planet itself.
