Fastest-growing black hole in the universe eats the equivalent of one sun per day
Fastest-growing black hole in the universe eats the equivalent of one sun per day
Astronomers have come across a monstrously large black hole with a gargantuan appetite. Each passing day, the insatiable void known as J2157 consumes gas and dust equivalent in mass to the sun, making it the fastest-growing black hole in the universe.
The sheer scale of J2157 is almost unfathomable, but we can try pinning some numbers on it nevertheless.
According to Christopher Onken, an astronomer at the Australian National University who was part of the team that originally discovered the object in 2019, J2167 is 8,000 times more massive than the supermassive black hole found at the heart of the Milky Way. That’s equivalent to 34 billion times the mass of the Sun.
In order for Sagittarius A*, the Milky Way’s supermassive black hole, to reach a similar size, it would have had to gobble two-thirds of all the stars in the galaxy.
For their new study, astronomers turned to ESO’s Very Large Telescope in Chile to get a more accurate assessment of the black hole‘s mass. The researchers already knew they were dealing with a black hole of epic proportions, but the final results surprised everyone.
“We knew we were onto a very massive black hole when we realized its fast growth rate,” said team member Dr. Fuyan Bian, a staff astronomer at ESO.
“How much black holes can swallow depends on how much mass they already have. So, for this one to be devouring matter at such a high rate, we thought it could become a new record holder. And now we know.”
Although black holes can’t be imaged directly because they don’t let light escape, J2157 is actually classed as a quasar, or “quasi-stellar radio source” — extremely bright objects powered by black holes at least a billion times as massive as our sun.
The bright signal of the quasar is formed by particles of dust and gas accreting around the edge of the supermassive black hole that are accelerated away at almost the speed of light. Practically, the black hole acts like an extremely powerful natural particle accelerator.
Luckily for us, the black hole is located many billions of light-years away. But this also means that astronomers are measuring J2157’s gravitational influence as it appeared in the distant past when the universe was still very young.
“We’re seeing it at a time when the universe was only 1.2 billion years old, less than 10 percent of its current age,” Dr Onken said.
“It’s the biggest black hole that’s been weighed in this early period of the Universe.”
Since then, J2157 likely grew even bigger, perhaps merging with several other black holes across the eons.
“With such an enormous black hole, we’re also excited to see what we can learn about the galaxy in which it’s growing,” Dr Onken said.
“Is this galaxy one of the behemoths of the early Universe, or did the black hole just swallow up an extraordinary amount of its surroundings? We’ll have to keep digging to figure that out.”
If Gene Roddenberry were alive today, he might look at the newly-formed US Space Force and wonder if the current administration owes him royalties. After all, the command responsible for the organization, training, equipping, commanding and controlling space forces is called SpOC (Space Operations Command} and their logo looks like the Starfleet emblem. And this week, the five-tiered bureaucracy of squadrons, groups, wings, numbered Air Forces, and major commands was replaced by a threesome of squadrons, field commands and ‘deltas’. Deltas? Does that sound familiar, Spock?
“This is the most significant restructuring of space units undertaken by the United States since the establishment of Air Force Space Command in 1982. Innovation and efficiency are driving our mission as we position the Space Force to respond with agility to protect our nation’s space capabilities and the American way of life.”
According to the Air Force press release, Secretary of the Air Force Barbara Barrett announced the restructuring this week as a way of making the organization “lean, agile and mission-focused.” However, “to protect our nation’s space capabilities and the American way of life” is a far cry from “to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no one has gone before.” Give it a chance, some say. Perhaps the Space Force will steal the Enterprise’s mission statement someday too, just like it has now taken ‘Delta’ – one of the most used words across the entire Star Trek world.
“Deltas will be O-6 led and will be organized around a specific function – operations, installation support, training, etc. Within the deltas will be squadrons focused on specific tactics. When the field command structure is fully implemented, it will eliminate one general officer echelon and one O-6 echelon of command.”
Well, that’s not exactly any of the Star Trek Deltas. The most famous one is the Starfleet insignia itself. The delta-shaped emblem was created by costume designer William Ware Theiss and was paired with other symbols to designate divisions: an elongated star for the Command division aboard ship; a planet for the Sciences division; an “e” stands for Engineering; and a red “Swiss Cross” for the Nursing Corps. In the Star Trek movies, Delta (or Delta IV) was a Federation planet inhabited by the humanoid Deltans. And on Star Trek:Voyager, the Delta Flyer was a shuttlecraft.
Do you see the connection, Mr. Spock?
However, the most famous of the Star Trek ‘Deltas’ was the Delta Quadrant – home of the Borg Collective and the area where the USS Voyager got stranded and spent the bulk of the series trying to escape. Other residents of the Delta Quadrant were the Kazon, the Vidiians, the Talaxians, the Ocampa, the Hirogen, and the Malon.
Patterning the Space Force after Star Trek would actually be a good idea – if it took the high concepts of Roddenberry’s creation rather than just cherry-picking names and logos. Unfortunately, the chance is also there that it will instead pick up the mission, or even worse, the attitude, of a very different group of Deltas — the fraternity from “Animal House.”
Let’s hope at least a few of the heads of the Space Force are Trekkies.
“First there is a mountain, then there is no mountain, then there is” ‘There Is a Mountain‘ by Donovan
Rock and Roll Hall of Fame member Donovan Leitch was inspired by a Buddhist saying to write those lyrics about finding one’s true nature. If a mountain can disappear, can something bigger … like a star? That the question astronomers are pondering after a massive star in a strange dwarf galaxy suddenly blinked out of existence and left nothing behind to indicate what happened or where it went. The next lines of the song compares it to a caterpillar shedding its skin to transform into a butterfly. Did this star shed its life and transform into something else other than a black hole? If so, this would be a first. Is it? Donovan? Buddhists?
“We investigate a suspected very massive star in one of the most metal-poor dwarf galaxies, PHL 293B. Excitingly, we find the sudden disappearance of the stellar signatures from our 2019 spectra, in particular the broad H lines with P Cygni profiles that have been associated with a massive luminous blue variable (LBV) star.”
In a research paper published this week in the Monthly Notices of the Royal Astronomical Society, astronomers from around the world reveal how the massive star they had studied between 2001 and 2011 suddenly disappeared when they went for a look in 2019. Located in the Kinman Dwarf (PHL 293B) galaxy in the Aquarius constellation about 75 million light years from Earth, this was a luminous blue variable star about 2.5 million times brighter than the Sun and in the latter stages of its life – although certainly not on its deathbed. Or so they thought.
“It would be highly unusual for such a massive star to disappear without producing a bright supernova explosion.”
Where was the supernova explosion?
In a European Southern Observatory (ESO) press release announcing the study, team leader and PhD student Andrew Allan of Trinity College Dublin describes using the ESPRESSO instrument (Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations) of the ESO’s Very Large Telescope (VLT) and the VLT’s four 8-metre telescopes simultaneously in August 2019. Finding no sign of the star, they suspected and error and switched to the VLT’s X-shooter instrument (“the ultimate weapon in intermediate resolution spectroscopy across a wide wavelength range, from the ultraviolet (UV) to the near-infrared (NIR)”) and still found no sign of the massive luminous star. With the Kinman Dwarf galaxy being too far away to see individual stars, they went back to older data which gave the astronomers a clue to what they had really been looking at.
“The old data indicated that the star in the Kinman Dwarf could have been undergoing a strong outburst period that likely ended sometime after 2011. Luminous blue variable stars such as this one are prone to experiencing giant outbursts over the course of their life, causing the stars’ rate of mass loss to spike and their luminosity to increase dramatically.”
Ah-ha! The luminous blue variable star was luminous because it was in a last blast of brightness and on its way out in 2011, or already “going gently into the night,” as team member Jose Groh, also of Trinity College Dublin, described it. As a result, the star may have dimmed considerably and is now blocked by a dust cloud. Or, the star collapsed into a black hole without producing a supernova – something only known to have occurred once before. As expected, the astronomers hope it’s the latter option, but can’t prove it because they can’t see the black hole … yet.
“Planned to begin operations in 2025, ESO’s Extremely Large Telescope (ELT) will be capable of resolving stars in distant galaxies such as the Kinman Dwarf, helping to solve cosmic mysteries such as this one.”
Will it come back?
Will they find a non-supernova black hole where the star was first? Donovan?
“Caterpillar sheds his skin to find a butterfly within.”
Then what?
“First there is a mountain, then there is no mountain, then there is”
Astronomy, like Buddhism and rock singers, can be comforting and frustrating at the same time.
An ongoing earthquake swarm in Iceland has now reached around 9,000 quakes, officials have said. The swarm, in the north of the country, began on June 19. Experts with the Iceland Meteorological Office (IMO) said activity is ongoing and more earthquakes can be expected.
In an updated statement on the IMO website, officials said there were two events above magnitude 3 on June 28. Both these earthquakes were felt in Siglufjordur and Ólafsfjordur—towns near to where they hit.
The IMO said that of the 9,000 earthquakes, three have been above magnitude 5. This includes a magnitude 5.8 earthquake on June 28. It said there is a chance of more earthquakes of this magnitude in the area.
What is causing the earthquake swarm is not known. Kristín Jónsdóttir, Earthquakes Hazards Officer for the IMO, told the Icelandic National Broadcasting Service RÚV: "We're trying to figure out what's going on."
She said the earthquakes are shallow and it could be that they are related to geothermal production in the region, as they are located near a geothermal power plant.
In an email to Newsweek, Jónsdóttir said the swarm is happening in a known fault zone called the Tjörnes Fracture zone. "Stress builds up in the zone because of tectonic plates which move past each other in opposite directions. This is the largest earthquakes swarm in the Tjörnes Fracture Zone recorded in the past 40 years."

IMO
"It is very difficult to say [when the swarm will end]," Jónsdóttir said. "The behavior is episodic, we record hundreds of earthquakes in a few hours and then it becomes quiet and all of a sudden it starts again. The last swarm in 2012 was ongoing for a few weeks. Let's hope we only have a few weeks to go."
Iceland sits on the Mid Atlantic Ridge and is slowly being torn apart. This is a tectonic plate boundary that separates the Eurasian and the North American tectonic plates. According to Volcano Discovery, the Tjörnes Fracture Zone is a zone that separates Iceland's northern volcanic zone from the Kolbeinsey Ridge.
The current swarm does not appear to have caused any damage to property. It has been linked with landslides and rocks falling near the epicenter. However, because of steep slopes in the area, researchers say these sorts of events have taken place before. Members of the IMO were flown to the region by the Icelandic Coast Guard for observations on June 21.
The earthquake swarm coincides with signs a volcano to the south may be about to erupt. The IMO said activity at the volcano, which is one of Iceland's most active, appears to be characteristic of an impending eruption. Since January, researchers have recorded uplift in the area, while in recent weeks scientists have recorded an increase in sulfur dioxide close to where two previous eruptions have taken place. Activity at the volcano has not been linked with the earthquake swarm.
This article has been updated to include quotes from Kristín Jónsdóttir.
Wat is er in hemelsnaam aan de hand op IJsland? 9000 aardbevingen in 10 dagen: ‘Grootste zwerm in 40 jaar’
Wat is er in hemelsnaam aan de hand op IJsland? 9000 aardbevingen in 10 dagen: ‘Grootste zwerm in 40 jaar’
Op IJsland hebben zich in 10 dagen maar liefst 9000 aardbevingen voorgedaan. De aardbevingzwerm begon op 19 juni in het noorden van het land. Experts van de IJslandse meteorologische dienst (IMO) verwachten nog meer bevingen.
Er zijn twee aardbevingen geweest die zwaarder waren dan 5 op de schaal van Richter. Zo is op 28 juni een beving met een kracht van 5,8 gemeten. Het is onduidelijk wat de bevingen veroorzaakt. Kristin Jonsdottir van de IMO zei tegen de IJslandse publieke omroep RUV: “We proberen te achterhalen wat er aan de hand is.”
Grootste aardbevingszwerm in 40 jaar
Jonsdottir vertelde aan Newsweek dat de bevingen zich voordoen in de Tjornes-breukzone, een gebied waar twee tektonische platen tegen elkaar schuren. “Dit is de grootste aardbevingzwerm in de Tjornes-breukzone in 40 jaar.”
“Het is heel moeilijk om te zeggen wanneer de zwerm voorbij zal zijn,” zei Jonsdottir. “De ene keer registreren we honderden aardbevingen in enkele uren tijd, de andere keer is het stil.” De vorige zwerm dateert van 2012 en duurde enkele weken.
Er zijn daarnaast aanwijzingen dat een vulkaan in het zuiden van IJsland mogelijk op uitbarsten staat, zegt de IMO verder. De afgelopen weken hebben wetenschappers een verhoogde concentratie zwaveldioxide waargenomen rond de vulkaan.
Ghostly shadow of a Medieval Castle suddenly appears on the ice sheet of Antarctica
Ghostly shadow of a Medieval Castle suddenly appears on the ice sheet of Antarctica
Explain: Until 12/10/2014 6am there is nothing to see on the ice sheet between Hutchinson Island and Cronenwell Island at Antarctica, then 1 hour later on 12/10/2014 7am the shadow of an enormous medieval castle becomes visible on the same spot.
Something went wrong with the Google Earth image processing or the appearance of the shadow is a mysterious and unexplained holographic projection from the past when it used to be ice-free until about 34 million years ago, before it became covered with ice.

Incredible: French film from 1947 predicts smartphones and other modern-day technology!
Inspired by an essay by Barjavel, the 70-year-old documentary proposes the evolution of television in transportable pocket format, and the way in which humans will interact with the objects. Today, parallels are drawn between the objects, like smartphones, described in the short documentary.
People using miniature-television devices in public places; professional meetings conducted via picture-phones; cars equipped with television screens; shops promoting their goods on television: these snapshots are taken from the 1947 short film Télévision: Oeil de Demain. Produced and shot by J. K. Raymond-Millet, Télévision.
Oeil de Demain combines documentary and science fiction sequences as it simultaneously offers a depiction of television in postwar France as well as imaginative speculations of the medium’s future developments.
While Raymond-Millet’s work is virtually forgotten today, his film Télévision has been applauded for ‘predicting our present’ and although the small handheld devices used in the film have long retractable antennas that resemble the first cell phones, it shows that '70 years ago, smartphones already existed. Actually they do mirror today’s smartphones that are in the pockets of nearly every human.
At the end of the movie, viewers are transported to the bedroom of a couple where a man is having trouble sleep. He seems to 'summon' a holograph of a dancing woman that appear at the bottom of the bed and watches it while his wife sleeps besides him.
The film’s sketching of coming televisual uses indeed appears as a rather precise forecasting of contemporary digital media with regard to the flexibility and hybridity of media technologies and their various consumption forms.
Now this is rare. Its not everyday you find a humanoid body laying on the surface of an alien planet. The body remains mostly intact and is defiantly not a statue. The legs are boney and dried out. One leg is even broken off at the knee. The other leg is mostly intact with a foot at the end. The chest and lower stomach area is different from humans in that its more reptilian like. The ribs seem to extend extremely low. The upper arms are less visible, but one arm can be seen behind the persons shoulder. The neck, ear, cheek, nose, eye and hair are all easily seen. The focus of the person is great, the quality of the photo is high. There is no doubt in my mind that this was an intelligent being which stood about 2 meters tall on Mars. For it to still exist, only two possibilities exit...first, its DNA is more than 2 different strands like we have, it must have 6-10 strands or more for its body to be so difficult to break down in the environment. Or second, it died recently.
I also found some other anomalies that are proof of alien life, but they pale in comparison to the alien body. You can see them below.

A 200,000 Year Old Annunaki Gold Civilization Might Rewrite History Books
A 200,000 Year Old Annunaki Gold Civilization Might Rewrite History Books
The discovery of ancient or even unknown civilizations has always fascinated archaeologists and scientists because such findings have added up to the known history by bringing in new episodes depicting the achievements of the old people who once dwelt on planet Earth.
However, when a team of archaeologists investigated this particular site, they couldn’t find a link between it and any other known culture. After carbon-14 was used in order to find the approximate time-period of the African remains, the archaeologists and historians were perplexed – the ruins were around since 160,000 to 200,000 years before Christ.
What makes this even more interesting is the fact that no advanced civilizations were thought to exist in South Africa in the past and that the first powerful cultures appeared in Sumeria, Egypt and other places.
When researcher and author, Michael Tellinger, teamed up with Johan Heine, a local pilot who had surveilled the area from above countless times, this mysterious settlement and its extreme importance was finally brought into discussion.
West of the port city of Maputo, about 150 miles inland, lies the remains of a colossal ancient metropolis that measures about 1,500 square miles and is considered part of an even larger picture measuring about 10,000 miles. Until recently, local people who encounters the strange stone foundations thought they were built by the indigenous people in the past and no one was attracted in discovering the exact origins, until Tellinger and Heine arrived.
When Heine first introduced me to the ancient stone ruins of southern Africa, he had no idea of the incredible discoveries we would achieve in the following years. The photographs, artifacts and evidence we accumulated, points towards a lost civilization that has never before been and precedes all others – not for a hundred years, or a few thousand years…but many thousands of years. – said Tellinger
The researchers were puzzled by the presence of so many gold mines remnants located in the vicinity of the ancient city. As Tellinger considers, this striking element shows how a timeworn civilization lived and prospered in this massive city while undertaking massive gold exploitations from the numerous mines around the settlement.
What they did with the gold remains a mystery because not much is known about a period so far away in time. Even though the site is only 150 miles away from an excellent port that could had facilitated a great way to ship their goods, we are still talking about 200,000 BC. Is it possible that they used the gold for trade or for sculpting statues and idols? Or could this enigmatic material possess a different, nobler value for these ancient people?
I see myself a fairly open-minded chap but I will admit that it took me well over a year for the penny to drop, and for me to realize that we are actually dealing with the oldest structures ever built by humans on Earth.
The main reason for this is that we have been taught that nothing of significance has ever come from southern Africa. That the powerful civilizations all emerged in Sumeria and Egypt and other places. We are told that until the settlement of the Bantu people from the north, which was supposed to have started sometime in the 12th century AD, this part of the world was filled by hunter gatherers and so-called Bushmen, who did not make any major contributions in technology or civilization. – Tellinger
The ancient ruins are scattered over an extremely large area. While most of them consist of circular stone circles buried in the sand, the climate change has blown the sand off, revealing other imposing structures with walls standing as high as 5 feet, while being over a meter in diameter; also roads were discovered, some extended over hundreds of miles, connecting the community and terraced agriculture.
NASA's plans to explore the ice moons of the Solar System are getting more detail as the space agency is developing a robot that would use steam to power itself in deep space.
In a post to its website, NASA's Jet Propulsion Laboratory notes researchers are developing a soccer-ball sized robot known as SPARROW (Steam Propelled Autonomous Retrieval Robot for Ocean Worlds) that "would use steam propulsion to hop across the sort of icy terrains found on Jupiter's moon Europa and Saturn's moon Enceladus."
"The terrain on Europa is likely highly complex," said Gareth Meirion-Griffith, JPL roboticist and the lead researcher of the concept, in the statement. "It could be porous, it might be riddled with crevasses, there might be meters-high penitentes" - long blades of ice known to form at high latitudes on Earth - "that would stop most robots in their tracks. But SPARROW has total terrain agnosticism; it has complete freedom to travel across an otherwise inhospitable terrain."
Moons In this artist's concept, a SPARROW robot uses steam propulsion to hop away from its lander home base to explore an icy moon's surface.
Both moons have been mentioned as candidates to possibly host life previously, including one study published in December 2019 that suggested they could be "indigenous."
By using steam to power the robot, SPARROW could thrive in the "low-gravity environment" on Enceladus and Europa, hopping "many miles over landscapes that other robots would have difficulty navigating," NASA added.
With its global ocean, unique chemistry and internal heat, Enceladus has become a promising lead in our search for worlds where life could exist.
Enceladus and Europa both likely have oceans that exist under a layer of ice crust. In 2019, researchers determined Enceladus' ocean is likely 1 billion years old, placing it in the sweet spot for supporting life.
In 2018, researchers acknowledged they had found the "building blocks" for life on Enceladus, having discovered complex organic molecules.
JPL notes that the SPARROW concept is dependent upon a lander to serve as a home base for it. The lander would "mine ice and melt it" prior to putting it on SPARROW, which would later heat it and create the steam necessary to power itself.
An artist's illustration of a plume of water vapor emanating from Jupiter's
JPL added that it's possible "many SPARROWs could be sent together, swarming around a specific location or splitting up to explore as much alien terrain as possible."
Enceladus is not the only celestial satellite of Saturn to intrigue scientists. In June, NASA announced the latest mission in its New Frontiers program. Known as Dragonfly, the mission will explore Saturn's largest moon, Titan, which could potentially host extraterrestrial life.
Two months later, NASA confirmed it would launch a mission to Europa, a trek that could answer whether the icy celestial body could be habitable for humans and support life.
A new study from scientists in the UK suggests that atmospheric dust could increase the habitability of some exoplanets, especially those orbiting red dwarf stars.

What makes a planet habitable? Various factors can affect a planet’s ability to sustain life, such as temperature, amount of water, composition of both the planet and its atmosphere and the amount of radiation from the host star. Last month, researchers in the U.K. said they’ve found that a common component of atmospheres – dust – could increase the habitability of some exoplanets.
This is a significant finding, since it suggests that planets with a lot of dust in their atmospheres could have habitable conditions farther from their stars than previously thought. This would, in effect, expand the habitable zone, which is basically the region around a star where temperatures on a rocky could allow liquid water to exist.
Researchers from the University of Exeter, the Met Office and the University of East Anglia (UEA) were involved in the new study.
Effects of dust on the climate of planets. For a tidally locked planet (a) and non-tidally locked planet (b), panels a–d show the base state of the planets, e–h show the short- (stellar) and long-wave (infra-red) forcing (change in surface energy balance) introduced by dust and i–j show the resultant effect of the forcing on the surface temperature. Blue arrows show the motion of the planet around the star, and green arrows show the rotation of the planet relative to the star.
Identification of habitable planets beyond our solar system is a key goal of current and future space missions. Yet habitability depends not only on the stellar irradiance, but equally on constituent parts of the planetary atmosphere. Here we show, for the first time, that radiatively active mineral dust will have a significant impact on the habitability of Earth-like exoplanets.
In our own solar system, Mars typically comes to mind when we think of a dusty world, yet it remains a cold, dry planet on the surface due to its very thin atmosphere. But for some exoplanets, especially those that are tidally locked to their stars, it could be a different situation. Ian Boutle, from both the Met Office and University of Exeter and lead author of the study, said in a statement:
On Earth and Mars, dust storms have both cooling and warming effects on the surface, with the cooling effect typically winning out. But these ‘synchronised orbit’ planets are very different. Here, the dark sides of these planets are in perpetual night, and the warming effect wins out, whereas on the dayside, the cooling effect wins out. The effect is to moderate the temperature extremes, thus making the planet more habitable.
The dust factor is especially significant for planets orbiting red dwarf stars, the most common type of star in our galaxy. Many planets around those stars are likely to be tidally locked, orbiting with one side of the planet always facing the star, just as the moon always keeps one side facing Earth. Those planets would have one side always in daylight, and the other always in darkness. If there is a lot of dust, that could help cool down the hotter day side, and warm the colder night side.
Artist’s concept of a cloudy and rocky exoplanet orbiting a red dwarf star. Dust in the atmospheres of planets like this could moderate the temperature extremes if the planets are tidally locked, helping to make them more habitable.
In an interesting scenario, dust could help hot planets retain their surface water, if they have any. A planet that is really hot, like Venus, could be cooled down by enough dust in the atmosphere. The amount of dust would then increase as water starts to be lost on the planet’s surface, which, ironically, in a process called negative climate feedback, would then slow down the loss of water. From the paper:
On tidally-locked planets, dust cools the day-side and warms the night-side, significantly widening the habitable zone. Independent of orbital configuration, we suggest that airborne dust can postpone planetary water loss at the inner edge of the habitable zone, through a feedback involving decreasing ocean coverage and increased dust loading.
The amount of energy a planet receives from its star is an important part of assessing habitability, but as Manoj Joshi from UEA noted, the composition of the atmosphere, including dust, is also very important:
Airborne dust is something that might keep planets habitable, but also obscures our ability to find signs of life on these planets. These effects need to be considered in future research.
The researchers performed a series of simulations of rocky Earth-sized planets and found that naturally occurring mineral dust can have a big impact on the habitability of such planets.
Mars is a very dusty place, and massive dust storms are common, but the dust doesn’t warm the planet much since the atmosphere is so thin.

Duncan Lyster, who ran an undergraduate experiment as part of the overall study (and now builds his own surfboards), also said:
It’s exciting to see the results of the practical research in my final year of study paying off. I was working on a fascinating exoplanet atmosphere simulation project, and was lucky enough to be part of a group who could take it on to the level of world-class research.
The researchers also point out that dust in a planet’s atmosphere must be taken into account when searching for possible biomarkers in that atmosphere. Those biomarkers could include gases such as oxygen, methane and ozone, and if there also was enough dust, the dust could obscure the detection of them, producing a false negative result. If potential biomarkers were missed in that way, the planet might be erroneously characterized as uninhabitable. Such biomarkers, which will be searched for with upcoming space telescopes like the James Webb Space Telescope (JWST) and others, will be a crucial aspect of the search for evidence of life beyond our solar system. Identifying them is already a challenge due to the extreme distances to these worlds, so knowing the amount of dust in a planetary atmosphere will be important as well. From the paper:
The inclusion of dust significantly obscures key biomarker gases (e.g. ozone, methane) in simulated transmission spectra, implying an important influence on the interpretation of observations. We demonstrate that future observational and theoretical studies of terrestrial exoplanets must consider the effect of dust.
Ian Boutle at the Met Office and University of Exeter, lead author of the new study.
Nathan Mayne from the University of Exeter, who assisted with the study, also noted how astrophysics in general will play a large role. He said:
Research such as this is only possible by crossing disciplines and combing the excellent understanding and techniques developed to study our own planet’s climate, with cutting edge astrophysics. To be able to involve undergraduate physics students in this, and other projects, also provides an excellent opportunity for those studying with us to directly develop the skills needed in such technical and collaborative projects. With game-changing facilities such as the JWST and E-ELT, becoming available in the near future, and set to provide a huge leap forward in the study of exoplanets, now is a great time to study physics!
The new assessment regarding exoplanetary dust will be very beneficial to scientists who will be looking for biomarkers and other evidence for habitable exoworlds, as well as studying how dust can affect a planet’s climate and environment overall.
Bottom line: Atmospheric dust could increase the habitability of some exoplanets.
Researchers have discovered the true colors of a group of fossilized insects, trapped in amber approximately 99 million years ago in Myanmar. The ancient insects include cuckoo wasps, soldier flies, and beetles, all bursting in metallic blue, purple, and green colors.
Nature is very visually rich but fossils rarely retain evidence of an organism’s original color. Nevertheless, paleontologists are now finding ways of teasing out colors from well-preserved fossils, whether they be dinosaurs and flying reptiles or ancient snakes and mammals.
Knowing the color of extinct species is actually very important, as it can tell researchers many things about the behavior of the animals. Colors could have been used to attract mates or warn off predators or even help with temperature regulation, for example. Knowing more about them can also help researchers know more about ecosystems and environments.
For the new study, a research team from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) looked at 35 individual amber samples with fantastically preserved insects trapped inside. The fossils were found in an amber mine in northern Myanmar.
“The amber is mid-Cretaceous, approximately 99 million years old, dating back to the golden age of dinosaurs,” said Cai Chenyan, the lead author, in a press release. “It is essentially resin produced by ancient coniferous trees that grew in a tropical rainforest environment. Animals and plants trapped in the thick resin got preserved, some with life-like fidelity.”
Colors in nature usually fall under three main categories: bioluminescence, pigments, and structural colors. The amber fossils found retained structural colors, which tend to be intense and rather eye-grabbing (including metallic colors) and are produced by microscopic light-scattering structures located on the heads, bodies, and limbs of animals.
The researchers polished the fossils using sandpaper and diatomite powder. Some pieces of amber were polished into very thin slices, making the insects clearly observable and the surrounding amber matrix almost transparent in bright light. The images included in the study were edited to adjust for brightness and contrast.
“The type of color preserved in the amber fossils is called structural color,” said Pan Yanhong, a co-author of the study, in a statement. “The surface nanostructure scatters light of specific wavelengths” which “produces very intense colors,” said Pan, adding that this “mechanism is responsible for many of the colors we know from our everyday lives.”

Among all the fossils, the cuckoo wasps were particularly stunning, with their heads, thorax, abdomen, and legs featuring hues of metallic blue-green, yellow-red, violet, and green. The color patterns were a close match to cuckoo wasps alive today, according to the research. Other standouts included blue and purple beetles and metallic dark-green soldier flies.
The researchers used electron microscopy to demonstrate that the amber fossils have a “well-preserved exoskeleton nanostructure that scatters light.”
“Our observations strongly suggest that the color preserved in some amber fossils may be the same as displayed by the insects when alive, some 99 million years ago,” wrote the authors in the study. “This is moreover corroborated by the fact that metallic blue-green coloration is frequently found in extant living cuckoo wasps.”
Let NASA go back to the Moon and Elon Musk go to Mars. People in the know (that’s you, me and the select few we tell) are planning trips to Neptune and Uranus to gather up buckets of diamonds raining from the clouds and bring them back to Earth. Crazy? Not according to a new study by Helmholtz-Zentrum Dresden-Rossendorf (HZDR) – not a law firm but a German research organization – which developed a way to analyze the hydrocarbon gas mixture enveloping these planets and found that they “can produce a kind of diamond rain.” When does the next rocket leave? And don’t forget to bring a big, strong sack!
“At SLAC National Accelerator Laboratory at Stanford University, the researchers studied the structure of the matter in mixtures that are typical for planets, in the case of ice giants, hydrocarbon, employing intense laser light. Standard plastic film served as a substitute for planetary hydrocarbon. An optical high-energy laser converts the plastic into warm dense matter: short, strong laser pulses generate shock waves in the film and compress the plastic to the extreme.”
Can you see any diamonds raining on Neptune?
According to the study, published in the journal Nature Communications, researchers at Stanford under the direction of Helmholtz-Zentrum Dresden-Rossendorf used a new technique based on X-ray scattering to simulate the conditions on Neptune, Uranus and similar gas exoplanets. The short, strong laser-generated shock waves create intense pressure — described as the equivalent of 250 elephants stacked on a human thumbnail (ouch!) – which heats the plastic up to 5,000 degrees F. Laser light is then aimed at the dense plastic and measured on how it scatters as it passes through. This light can then tell them about the structure of the matter. That’s when they made a startling discovery.
“The researchers observed that in a state of warm dense matter, what was formerly plastic produces diamonds. The high pressure can split the hydrocarbon into carbon and hydrogen. The carbon atoms that are released compact into diamond structures. In the case of planets like Neptune and Uranus this means that the formation of diamonds in their interior can trigger an additional energy source. The diamonds are heavier than the matter surrounding them and slowly sink to the core of the planet in a kind of diamond rain.”
Diamond rain! Take your protein pills and put your helmet on! OK, it’s not quite a piece of Neptunian cake to scoop up handfuls of diamonds like the scientists simulated. For one thing, these are ice giants and the rain is falling on their cores, which are 10,000 km (6,200 miles) deep below layers of hydrogen, helium, hydrocarbons, possibly nitrogen, and ices made of water, ammonia and methane. It’s that methane which forms the diamonds as the pressure heats it up while separating it into carbon and hydrogen. And, while the researchers guarantee that this carbon is in the form of diamonds, they don’t say how big they are nor what the daily rainfall totals are. Is Neptune Seattle or the Sahara? Are they keeping this information for their own trips to the planets?
How about on Uranus?
“Moreover, this method will enable unprecedented measurements of mixing/demixing kinetics in dense plasma environments, e.g., induced by chemistry or hydrodynamic instabilities.”
Being typical scientists, they’re more excited about the new process for studying gas exoplanets than the end result of diamond rains. This is why we need research AND development. There are few things as motivational as greed (sad as that is to say) so this discovery could someday drive the development of large, long-distance mining ships in operations that mimic both science fiction and the age of resource discovery and exploitation on Earth.
On second thought, perhaps we need another letter at the end of space R&D – E for ethics.
Are you planning your first post-coronavirus-shutdown vacation? Looking for a place where you can get away from it all … except UFOs? Then stop throwing darts at a map (does anyone really do that anymore?) and Google a direct route to Idaho – the new UFO capital of the United States.
Did he say Idaho? Home of hot springs, great skiing and the Idaho Potato Museum?
Yes, Idaho. The Idaho Statesman proudly announced that the Gem State (its slogan is: “Great Potatoes. Tasty Destinations”) whose name is a Shoshoni exclamation which translates roughly to “Behold! The sun coming down the mountain!” had the highest per-capita rate of UFO sightings in the U.S. between January 2019 and June 2020. Over that time period, Idahoans reported 164 UFO sightings. With a 2019 population of 1,787,065, that adds up to 9.18 sightings per 100,000 people, just squeaking by Montana at 9.17 per 100K and well ahead of #3 New Hampshire at 7.87. These numbers were compiled by the Satellite Internet website using data from the National UFO Reporting Center.
Wait a minute! (Not a Shoshoni exclamation but appropriate here.) Idaho’s population density is only 21.6 people per square mile, while my state’s is (fill in the blank with any higher number – unless you live in New Mexico, South Dakota, North Dakota, Wyoming, Alaska and yes, Montana where there’s even less people watching for UFOs.)
Yes, you’re right. Florida has the highest number of UFO sightings over the same 18-month period (567) and is eighth in population density, which puts it at #36 with 2.64 per 100K people. But Florida has plenty of other strange things going on and plenty of explainable reasons why its population is seeing so many UFOs. On the other hand, Idahoans have clear skies and little light pollution. Is this why more of them are seeing UFOs or do aliens like potatoes too?
Come for the UFOs … stay for the scenery.
“The reality is most UFO sightings are less dramatic, such as a strange aircraft or odd light formations descending slowly into a forest. Planets are also sometimes mistaken for UFOs. You can get to know the stars and planets with apps like Sky Map, NASA, or Star Walk 2 so you don’t file a report on Venus. Another common error is mistaking a Starlink satellite chain for a UFO.”
Satellite Internet admits what the rest of us should already know but so many I-want-to-believe-ers refuse to accept about UFOs — a lot of them are SpaceX’s satellites (curse you, ELon Musk!). However, in the spirit of fairness, it points out that “up to 5% of UFO reports remain unexplained.”
“Idaho wants to believe: Our state has highest per-capita UFO sightings in the country.”
That’s the message for the good citizens of Idaho and the good citizens of the rest of the states who are ready to bust out of coronavirus lockdown and get up close and personal (within a proper social distance, of course) with some UFOs and possible extraterrestrials. Idaho has parks mountains, water, skiing, fresh air, potatoes … and UFOs. So plan your trip to Idaho and get ready to …
For a few decades, sightings of large, triangular-shaped UFOs, usually described as being black in color, very often with rounded – rather than angled – corners, and that make a low humming noise, have been reported throughout the world. The sheer proliferation of such reports has led some ufological commentators to strongly suspect that the Flying Triangles (as they are known) are prime examples of still-classified aircraft, the development of which was secretly begun in the early 1980s by elements of the United States’ Department of Defense and Air Force. And while it would, of course, be foolish to completely rule out such a scenario, the fact is that when placed under scrutiny, this argument doesn’t completely stand up. As my extensive research demonstrates, the Flying Triangles have been with us for a very long time. Indeed, far longer than most people have realized. As you will now see.
There is a report of a Flying Triangle-style UFO described in officially-declassified U.S. Air Force documents of May 26, 1949. The account originated with the Air Force Office of Special Investigations at Barksdale Air Force Base, Louisiana. According to Special Agent Bernard A. Price: “Investigation at Vicksburg, Mississippi regarding an unidentified aerial phenomena described as being a flying triangle, failed to verify definitely just what type of object was sighted.” In this particular case the object, which was seen on the night of April 22, 1949, was relatively small in size when compared to its present-day equivalents; but was described by the witness to Special Agent Price as moving “faster than mail planes, or National Guard planes, but slower than a jet type aircraft.” Also, the object reportedly did not exhibit “any kind of propulsion,” nor “stabilizers or antenna.”
Moving on: in September 1952, the North Atlantic Treaty Organization (NATO) coordinated a huge military exercise in the North Sea and North Atlantic. Code-named Mainbrace, the exercise utilized the armed forces of Britain, the United States, Canada, Norway, Denmark, France, the Netherlands, and Belgium. Approximately 85,000 personnel took part; the purpose of which was to demonstrate to the then-Soviet Union that NATO was fully prepared to withstand, and counter, any possible assault on Western Europe. Only twenty-four-hours into the exercise two reports of encounters with unidentified flying objects were filed with British, American and NATO authorities by naval personnel on board ships in the Atlantic between Ireland and Iceland. The first involved a “blue-green triangle” that was observed flying high shortly after dawn broke over the sea at a speed estimated to have been no less than 1,500 miles-per-hour. Later that same day, a similar-shaped craft – but this time emitting a “white light exhaust” – was reported to the U.S. Air Force’s UFO investigative body known as Project Blue Book.”
Then, on the night of September 9, 1960, an unidentified flying object, described as a “triangular formation of lights with a red light in the center,” was viewed by various people in the Consett, South Shields, Fawdon, and Fenham areas of the British city of Newcastle. Leslie Otley said that his wife and two neighbors saw the UFO circling over Fenham between 9:15 p.m. and 9:40 p.m. “A friend of mine, Mr. A. Miller, telephoned to say he saw them too, over Consett at 8:30 p.m.,” added Otley, who telephoned a local Royal Air Force base – RAF Acklington – to report the encounters. After having been firmly pressed by the Newcastle Evening Chronicle newspaper for a comment, a spokesman at RAF Acklington admitted that he had indeed received two independent reports of the mystery object, and said that these were duly being forwarded to the Air Ministry at London for examination. He also added, somewhat cryptically, to the newspaper that: “I have no further information about this, and even if I had, we are not allowed to release information.”
For the most convincing evidence that exists to support the notion that Flying Triangles – identical to those seen today – were being viewed much earlier than many students of the mystery would have us believe, we have to turn our attention to, once again, the U.K. – but this time to early 1965. While digging through a whole host of formerly classified UFO files at the National Archive at Kew, England in 1996, I uncovered a one-page document that revealed some truly startling data. As the relevant, now-declassified Ministry of Defense paperwork stated, on March 28, 1965, at around 9:30 p.m. near the town of Richmond, North Yorkshire, a man saw, “Nine or ten objects—in close triangular formation each about 100ft long—orange illumination below—each triangular in shape with rounded corners, making low humming noise.” The “rounded corners” and “low humming noise” are precisely what many witnesses to Flying Triangle-style UFO encounters reported throughout the late 1980s and 1990s, and continue to report to this day.
Shortly after midnight on Sunday, August 28, 1977, a large object – that fits the description of those discussed thus far – was seen by more than ten police officers and several members of the public in and around the Windermere area of Cumbria, England. Sergeant James Trohear described the “triangular or slightly diamond-shaped” nature of the craft; while another officer commented that it “resembled the shape of a stingray fish.” Meanwhile, Constable David Wild added that it appeared to be “kite-shaped, or like a skate fish,” adding that it was “very large and solid in construction.” It, like so many other sightings of a similar nature, was classified as unexplained.
Found in the released records of a now-defunct Ministry of Defense office known as Defense Secretariat 8, is a photo-copy of a long letter written by Mark Birdsall – the brother of the late Graham Birdsall, of UFO Magazine, and who was heavily active in UFO research in the late 1970s and throughout the 1980s and 1990s. Dated March 27, 1984, the letter from Mark requested access to any and all official data pertaining to a certain UFO incident, the details of which, Mark explained, were known to “a high ranking RAF [Royal Air Force] officer and thirteen others,” and that had occurred in early 1981. Mark added to the Ministry of Defense that his informant had advised him that “the incident” involved the sighting of a huge, triangular-shaped object over a military base on Cyprus. It was described as being “silver [and] hanging motionless in the sky at 60,000 feet.” The Flying Triangle, Mark elaborated, was 100 meters in length by 50 meters wide and, according to his sources, was apparently tracked on radar as well as having been sighted visually. On April 24, 1984, declassified Ministry of Defense files reveal, a DS8 representative replied to Mark Birdsall’s letter and advised him that they had “no record” of any such incident on file. To this day, the case remains unresolved.
Contrary to the popular belief perpetuated by elements of the world-wide UFO research community, we now know that sightings of the mysterious Flying Triangles have proliferated for, quite literally, decades: the forties, fifties and sixties. They are most assuredly not a relatively recent development. Had we – and by “we” I mean the collective Human Race – been designing, building and flying huge triangular-shaped, high-performance aircraft in the 1950s and 1960s, then surely they would not still be subject to an overwhelming blanket of secrecy to this very day. More likely, they would either have been put to regular use in a battlefield environment, or the projects would have been canceled as not being seen as ultimately viable. Either way, we would by now have widespread awareness of their existence, in much the same way that the existence of the famous U-2 spy-plane of the Cold War, and today’s F-117 Stealth Fighter and the B-2 Stealth bomber have been acknowledged. The fact that we do not have such awareness, however – and the fact that the UFO research community is still scratching its collective head as it seeks to resolve the puzzle – suggests strongly that the Flying Triangle has a far stranger point of origin. Those who seek a definitive answer to the conundrum of the Flying Triangle might be very wise to turn their attentions away from restricted military bases and firmly towards the distant heavens.
WETENSCHAPHet Amerikaanse ruimtevaartagentschap NASA stelt de lancering van zijn gloednieuwe Marsrobot Perseverance – het middelpunt van de veelbelovende Marsmissie – met enkele dagen uit. Dat is te wijten aan problemen met de Atlas-V draagraket.
Het is niet de eerste keer dat de lancering wordt uitgesteld. Dat gebeurde driemaal: de ene keer voor een defect, nog een andere keer voor een verontreinigingsprobleem. Dit keer wordt de lancering met enkele dagen uitgesteld, de lanceerdatum schuift op van 17 juli naar 30 juli. En veel langer kan die overigens niet uitgesteld worden, gezien het lanceervenster nauw is en tot 15 augustus loopt.
Zolang de Marsrover binnen dat lanceervenster gelanceerd wordt, zal hij in februari 2021 op de rode planeet landen. Daar moet de Perseverance zoeken naar sporen van vroeger microbiologisch leven. Bovendien moet de robot het klimaat en de geologie van onze buurplaneet onderzoeken, door het nemen van stalen van stenen en stof. De missie moet tevens toelaten nieuwe technologie voor toekomstige onbemande en bemande missies naar Mars te testen.
Wetenschappers willen ook meer leren over het ontstaan van het universum.
WETENSCHAPWaar is toch die massarijke ster gebleven, een ster maar liefst 2,5 miljoen keer helderder dan de zon? Astronomen staan versteld. In 2011 hadden collega’s de ster ver weg in het Kinman-dwergstelsel nog - indirect - gespot, vorig jaar was ze plots verdwenen. Mogelijk is de ster ingestort tot een zwart gat, zónder voorafgaande supernova-explosie. “Dat zou dan de eerste directe waarneming zijn van een monsterster die zijn leven op deze manier afsluit”, weet de Ierse onderzoeksleider, Andrew Allan.
Doctoraatsstudent Andrew Allan van het Trinity College Dublin in Ierland en zijn team vragen zich af waar de ster gebleven is die zich op zo’n 75 miljoen lichtjaar van ons bevindt - of bevond - in het Kinman-dwergstelsel in het sterrenbeeld Waterman. Collega-astronomen hadden de zware ster nog bestudeerd tussen 2001 en 2011. Hun waarnemingen deden veronderstellen dat de ster op haar laatste benen liep, maar een supernova kwam er kennelijk niet.
Het Kinman-dwergsterrenstelsel ligt op 75 miljoen lichtjaar en dat is te ver om aparte sterren te kunnen onderscheiden, maar astronomen kunnen wel de kenmerkende ‘handtekening’ van sommige ervan ontwaren. Het onderzoek tussen 2001 en 2011 liet zo het bestaan van een lichtsterke blauwe variabele ster vermoeden, ook hyperreus genoemd. Dit type is instabiel, met soms dramatische veranderingen in de helderheid en in de hoeveelheid licht die ze in verschillende golflengtes uitstralen. Maar zelfs dan laten ze sporen achter. Zoals deze ster, ongeveer 2,5 miljoen keer zo helder als de zon.
In 2019 wou het team van Andrew Allan meer te weten komen van hoe dat soort zeer massarijke sterren aan zijn einde komt. Maar zelfs met de Very Large Telescope (VLT) van de Europese Zuidelijke Sterrenwacht (ESO) konden ze de vroegere aanwijzingen die wezen op het bestaan van de bewuste ster niet meer terugvinden. “We stonden versteld: de ster was weg”, aldus Allan. Wat was er gebeurd? “Het zou erg ongewoon zijn dat zo’n massarijke ster verdwijnt zonder een heldere supernova-explosie”, voegde hij eraan toe. “Mogelijk hebben we een van de meest massarijke sterren in het lokale heelal als een nachtkaars zien uitgaan”, zei teamlid Jose Groh, ook van het Trinity College Dublin.
De gegevens van de oude waarnemingen wezen op gigantische erupties, waarbij materiaal van de ster verloren gaat. Die moeten ergens na 2011 opgehouden zijn. Zulke uitbarstingen zijn niet ongewoon voor lichtsterke blauwe variabele sterren, die zo in korte tijd veel massa verliezen, waardoor hun helderheid fel toeneemt.
In dit geval zou de bewuste zware ster door de uitbarstingen kunnen zijn getransformeerd in een minder heldere ster, die bovendien nog eens deels verduisterd kan zijn door stof. Dat zou een reden - waarschijnlijk de meest plausibele - kunnen zijn waarom de ster verdwenen lijkt.
Een andere verklaring volgens het wetenschapsteam rond Allan is dat de ster wel degelijk is ineengestort tot een zwart gat, maar dan zonder dat er eerst een supernova-explosie plaatsvond. Dat zou uiterst zeldzaam zijn en indruisen tegen de huidige kennis over het einde van massarijke sterren die stelt dat zij hun bestaan wel degelijk afsluiten met een supernova.
De studie van het onderzoeksteam is gepubliceerd in de Monthly Notices of the Royal Astronomical Society.

Chance Encounter with Mysterious Orb Changed Man's Life Forever
Chance Encounter with Mysterious Orb Changed Man's Life Forever
COAST TO COAST AM – Preston Dennett shared the case of Jim Schaffer, whose medical records show he had been diagnosed with cancer. After an encounter with an orb that entered his body, Schaffer’s neck tumor disappeared. Surgery to remove tissue there showed no trace of cancer, Dennett reported, adding he has seen 40 documented cases of patients healed of cancer by the power of UFOs.
He shared the case of a police officer in Texas struck by a beam of light which healed an animal bite he had on his arm. There are numerous other incidents of people hit by beams of light and healed of everything from the common cold to major injuries, and in one instance a man even grew new teeth, Dennett revealed.
There appears to be a large disk shaped craft leaving from within our sun. The object is huge and as it moves out its form is clearly a huge round object, but as it moves away, the object fades and vanishes as if it soon cloaked the ship to go undetected. Interesting video and very difficult to tell for sure for or against it due to the poor video quality that NASA puts out. Scott C. Waring - Taiwan
