The green flash image at the top of this post was taken by Jim Grant, an EarthSky friend onFacebook. He captured it off the coast of Ocean Beach, California, and identified it as a mock mirage green flash.
It’s not hard to see a green flash with the eye alone, when sky conditions are right, and when you’re looking toward a very clear and very distant horizon. That’s why those who live near an ocean tend to report green flashes most often. A sea horizon is the best place to see them.
The video below, posted to EarthSky by Vladek in 2016, is an excellent example of the experience of seeing a green flash:
Most people see green flashes just at sunset, at the last moment before the sun disappears below the horizon. Be careful and don’t look too soon. If you do look too soon, the light of the sunset will dazzle (or damage) your eyes, and you’ll miss your green flash chance that day. But if you wait – looking away until just the thinnest rim of the sun appears above the horizon – that day’s green flash could be yours.
Of course, the green flash can be seen before sunrise, too, although it’s harder at that time of day to know precisely when to look.
Mock mirage and green flash seen from San Francisco in 2006.
There are many different types of green flash. Some describe a streak or ray of the color green … like a green flame shooting up from the sunrise or sunset horizon.
The most common green flash, though – the one most people describe – is a flash of the color green seen when the sun is nearly entirely below the horizon.
Again … you need a distant horizon to see any of these phenomena, and you need a distinct edge to the horizon. That’s why these green flashes, streaks, and rays are most often seen over the ocean. But you can see them over land, too, if your horizon is far enough away. Pollution or haze on the horizon will hide this instantaneous flash of the color green.
Jim Grant photographed this green flash on April 27, 2012, off the coast of San Diego.
And, of course, Les Cowley at the great website Atmospheric Optics devotes many pages to the green flash phenomenon. Notice the menu bar at the left side of the page; it’ll let you explore many different types of green flashes.

Bottom line: The green flash is legendary, and some people have told us they thought it was a myth, like a unicorn or a pot of gold at the end of a rainbow. But green flashes are very real. You need a distant and exceedingly clear horizon to see them at the last moment before the sun disappears below the horizon at sunset.
A STAR IS CIRCLING A BLACK HOLE AND ITS ORBIT IS ABSOLUTELY NUTS
A STAR IS CIRCLING A BLACK HOLE AND ITS ORBIT IS ABSOLUTELY NUTS

Cosmic Dance
A star orbiting the supermassive black hole at the center of the Milky Way has a bizarre orbit — but also one that strongly supports Einstein’s theories.
After monitoring the star, dubbed S2, for 27 years straight, astronomers from the Max Planck Institute determined that it traces a distinct flower-like shape as it orbits, CNN reports. The fact that the star makes a rosette as it travels supports Einstein’stheory of general relativity, which predicts that such a pairing would remain dynamic instead of fixed in a set, ellipse-shaped orbit.
Exhaustive Evidence
S2’s orbit around the black hole Sagittarius A* isn’t the first evidence for the theory of general relativity — but the research, published last month in the journal Astronomy & Astrophysics, strengthens the idea even further.
“This famous effect — first seen in the orbit of the planet Mercury around the Sun — was the first evidence in favor of general relativity,” Reinhard Genzel, director at the Max Planck Institute for Extraterrestrial Physics, said in a press release. “One hundred years later we have now detected the same effect in the motion of a star orbiting the compact radio source Sagittarius A* at the center of the Milky Way.”
Indirect Discovery
The decades of data have an added bonus — it helps confirm scientists’ theories about the size and behavior of the black hole itself.
“This observational breakthrough strengthens the evidence that Sagittarius A* must be a supermassive black hole of 4 million times the mass of the sun,” Genzel added.
An international team of scientists have discovered an exciting Earth-sized exoplanet that’s capable of supporting liquid water.
“This intriguing, distant world gives us even greater hope that a second Earth lies among the stars, waiting to be found,” Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington, who was not part of the research, said in a statement.
The exoplanet, called Kepler -1649c, orbits its small red dwarf star within the system’s habitable zone, a distance at which rocky planets receive enough star radiation to allow for liquid water to exist. It’s almost precisely the same size as large as Earth and receives 75 percent of the amount of light Earth receives from the Sun.
In other words, it’s a distant world that’s likelier than many others to support life. At 300 light-years from Earth, it’s the most similar to Earth in size and estimated temperature out of the thousands of exoplanets discovered by the Kepler space telescope, according to the researchers.
But plenty of questions remain before we can definitively say that the planet is capable of supporting life. For one, we don’t know what its atmosphere looks like — the key determinant of the planet’s surface temperature.
The team made the discovery while re-analzying older observations from NASA’s now-retired Kepler space telescope program. Kepler -1649c orbits its star at an extremely short distance — a full revolution takes only 19.5 Earth days — alongside a similarly sized rocky planet that orbits at half the distance of Kepler-1649c.
“Out of all the mislabeled planets we’ve recovered, this one’s particularly exciting — not just because it’s in the habitable zone and Earth-size, but because of how it might interact with this neighboring planet,” Andrew Vanderburg, researcher at the University of Texas at Austin and lead author of the paper published today in The Astrophysical Journal Letters, said in the statement.
The two rocky planets orbit their host star at an exact ratio: Kepler-1649c completes nine orbits in almost exactly the same time the inner planet completes four orbits. The researchers believe this could make the system extremely stable over a long period of time.
“The more data we get, the more signs we see pointing to the notion that potentially habitable and Earth-size exoplanets are common around these kinds of stars,” said Vanderburg.
“With red dwarfs almost everywhere around our galaxy, and these small, potentially habitable and rocky planets around them, the chance one of them isn’t too different than our Earth looks a bit brighter,” he added.
IS THE INTERSTELLAR VISITOR 'OUMUAMUA A FRAGMENT OF A SHATTERED ALIEN WORLD?

IS THE INTERSTELLAR VISITOR 'OUMUAMUA A FRAGMENT OF A SHATTERED ALIEN WORLD?
So it's been an interesting week for comets. 2I/Borisov, the second interstellar comet we've ever seen, split in half; the comet we were hoping would be the brightest of the year (C/2019 Y4 ATLAS) instead disintegrated; and the first interstellar comet we've ever seen, 'Oumuamua, may be a shard shredded off a planet that got torn apart by its dying host star.
The first alien visitor to our solar system ever found shocked astronomers when it first appeared in 2017. Seen in observations by the Pan-STARRS telescope, it immediately was seen to be weird, moving on an orbit that looked like it came from deep interstellar space. The orbit was hyperbolic, meaning the object was moving too quickly to be bound to the Sun. It must have come from another star.
Then it got weirder. It tumbles, flipping end over end, roughly once every eight hours. These observations also indicated it's extremely elongated, at least five times longer than it is wide, so it's kinda cigar-shaped. That’s bizarre. We don’t see any objects in our solar system that elongated.
Then it got weirder again. As it headed away from the Sun it slowed down, as expected from the Sun's gravity pulling it, but it wasn't slowing down rapidly enough. The most likely reason is that it was outgassing, with ice turning to gas and expanding away, acting like a very low-power rocket. But sunlight-reflecting dust escaping with the gas would make it easy to see, yet nothing was seen around it!
They looked at what would happen if an object like a rubble pile asteroid — literally a bunch of rocks held together by their own gravity, a very common structure for small bodies in our solar system — got too close to its star. They found that if it gets too close, the tides from the star will tear it apart. That's old news (in that we know things getting too close to stars can be ripped into pieces), but they also found that the heat from the passage does two things. First, the object is sintered; tiny particles break off and recollect onto it, and as they do they tend to fall on the ends pointing toward and away from the star due to tides, elongating the object. That's pretty cool! Second, a lot of stuff that vaporizes at lower temperatures goes away, leaving behind a hardened crust.
Artwork depicting why ‘Oumuamua is so elongated; as particles were boiled off a more spherical object, tidal forces guided them to the longer ends, stretching the shape out.
This does explain a lot of 'Oumuamua’s behavior and appearance. But they also found that long-period comets (with orbits hundreds or thousands of years long) that pass very close to their host stars can also break up and create shards like 'Oumuamua in a similar way, providing a second creation path.
And there's a third that's pretty interesting. They looked at planets being the source. A super-Earth, bigger and more massive than Earth, on a highly elliptical orbit its star (maybe poked gravitationally by a second star in the system and dropped too close to the first star) can be disrupted in the same way, and if the pass is close enough the process winds up being similar to what happens to the rubble pile asteroids and long-period comets. It may be somewhat less likely, but a single event like that can create a lot of 'Oumuamuas. Billions. More.

If the star is a white dwarf — the remains of a star like the Sun after it uses up its nuclear fuel and blows off its outer layers, leaving just the hot and very dense core behind — then this process is really efficient. White dwarfs have immense gravity, and can easily tear a planet to shreds. Moreover, we have tons of evidence this actually happens. That’s terrifying — the idea of planets being torn apart like the Cookie Monster going to town on a snickerdoodle — but the Universe really seems to like ripping up perfectly good things like asteroids and comets and planets.
So this work is theoretical, using physical models of how objects break up, so the question is: Is it right? The prediction it makes is that we'll see a lot more objects as elongated as 'Oumuamua, so what we need to do is find more! Extrapolating from these observations indicates that interstellar bodies like 'Oumuamua are relatively common, it's just that we haven't been able to see them (and follow up on them with big observatories) until recently. So we'll see. If the next ten in a row are more like Borisov then that's hard to explain this way, but if they look more like 'Oumuamua then maybe this idea holds water.
I love that there are so many ideas about what this thing is. But that's par for the course in science; when something new and strange is found, tons of ideas bubble up. More observations eliminate lots of them, and the ones that survive get tested even more. Eventually one or a few survive, and these become the standard against which other ideas must compete.
It's like evolutionary science for science itself, and the process helps us find our way to the truth. I’m really curious what the truth is about 'Oumuamua, and hopefully we’ll have a lot more such beasts to look at that will help us along the path to finding it.
WETENSCHAP & PLANEET Waar kwam de sigaarvormige ruimterots vandaan die drie jaar geleden plots in ons zonnestelsel verscheen? Was het een komeet? Of een buitenaards ruimteschip, zoals zelfs een gerenommeerde wetenschapper suggereerde? Een computersimulatie werpt nu nieuwe licht op de zaak.
Het was eind 2017 dat de wetenschappelijke wereld plots op zijn kop stond. Voor de allereerste keer was er een object waargenomen in ons zonnestelsel dat er niet uit afkomstig was.
Het rotsachtige voorwerp had de ongewone vorm van een sigaar en werd Oumuamua gedoopt. Dat betekent ‘boodschapper van ver weg die als eerste aankomt’ in het Hawaïaans. Het was dan ook een observatorium in die Amerikaanse staat dat het object voor het eerst zag.
Meteen rees de vraag wat het tollende ruimteobject was. Was het een gewone ruimterots? Een asteroïde van een andere ster? Of een ruimteschip van een andere planeet, zoals zelfs een wetenschapper van de gerenommeerde universiteit van Harvard opwierp?
Volgens een nieuwe computersimulatie zou het om scherf van een dode planeet kunnen gaan. Dat schrijven onderzoekers in het wetenschappelijke tijdschrift Nature. Volgens hen is hun uitleg de enige die de bijzondere vorm van het object kan verklaren. En het geeft ook een uitleg voor de manier waarop het object draait en versnelt.
Volgens de auteurs van de studie – Yun Zhang van de Côte d’Azur Observatory in Frankrijk en Douglas Lin van de universiteit van Californië – kan Oumuamua van een stelsel komen met een kleine en dichte ster. Een ster met voldoende zwaartekracht dat ze planeten en andere objecten in stukken kan scheuren zonder ze eerst op te branden.
via REUTERS
De onderzoekers tekenden de mogelijke banen uit voor drie types van objecten: planetesimalen (waaruit planeten gevormd kunnen worden) van een halve kilometer groot, bevroren objecten zoals kometen en grote planeten. Wat bleek? Als elk van die objecten binnen een afstand van 350.000 kilometer van de ster zou komen, zouden ze opgewonden, uitgerekt en in stukken gescheurd worden door de zwaartekracht van de ster.
Afhankelijk van de samenstelling van het object zou zo een object kunnen ontstaan dat eruit ziet als Oumuamua en de ruimte in geslingerd wordt. Zo zou Oumuamua – mogelijk na miljoenen jaren – in ons sterrenstelsel terechtgekomen kunnen zijn.

Ancient Alien Base And Ship Found On Mars, NASA Photo, UFO Sighting News.
Date of discovery: April 15, 2020
Location of discovery:Mars
Source photo: Coming soon.
Hey guys, I was looking through the NASA Mars photo index from the Mars Global Surveyor missions and found an unusual structure. I believe the photo was taken in 1999 and shows a huge rectangular structure with a large opening in it. The opening seems to go below the ground, which leads me to think there is an underground alien base here...or at least there was once long ago. To the right of the structure is a very unique ship thats docked inside of a crater. The ship has layers and long coming out of its front and top...kid of like a telescope coming out of submarine. They are docked inside the crater to give it some saftey from both detecting and micrometeorites. The micrometeorites wont hurt the ship, but if repairs are being made, it may injure those doing the repairs. Scott C. Waring - Taiwan

UFO Caught Moving Over City Of Seville, Spain, Video Proof, UFO Sighting News.
UFO Caught Moving Over City Of Seville, Spain, Video Proof, UFO Sighting News.
Date of sighting:March 15, 2020 Location of sighting:Seville, Spain A glowing pinkish sphere appeared over Seville, Spain last month. It moved slowly across the horizon and then became smaller and disappeared on video. The UFO moved slowly and smoothly, unlike an aircraft or helicopter. Its lights were not those of any aircraft I have ever seen before, and I was in the USAF working on the flight line with B1 bombers. This is very cool, very abnormal and important video. You see it shows us not only the UFO, but how it smoothly it moves across the sky, how it stops, how it shoots away so fast that it literally looks like it disappeared. Fantastic and important evidence before us. Scott C. Waring - Taiwan

A young Neanderthal girl kneels at the water's edge as host Neil deGrasse Tyson looks on. Until about 40,000 years ago, our Neanderthal relatives lived very much as we did.
Religion and worship are intrinsically tied with our history as a species, as is fire, and both are recurring motifs in this week's episodes of "Cosmos: Possible Worlds."
At the beginning of episode 11, called "Shadows of Forgotten Ancestors," host Neil deGrasse Tyson reminds us that when Homo sapiens, which means "wise ones," discovered and controlled fire hundreds of thousands of years ago, everything changed. Fire allowed us to cook food and heat dwellings, and it served as a focal point for storytelling and sharing cultural identity among community members.
Persepolis, a complex built by emperors around 600 BCE when Persia was the only superpower on Earth, illustrates the central focus fire had in ancient civilization. The domestication of fire played a crucial role in the worship of the Zoroastrian god, Ahura Mazda, and symbolized the god's purity and the "light of the illuminated mind."
Evil, catastrophe and disease, on the other hand, were caused by Angra Mainyu, the Zoroastrian representation of what modern Christian societies would call the devil. Why people thought of these maladies as being the creation of an evil being becomes more obvious as Tyson walks us through how a rabies virus invades a dog's body after the pup has been infected by a rabid bat.
Disease microbes not only attack and kill cells, Tyson explains, but also change their hosts' behavior to facilitate the virus' spread to other hosts. The rabies virus, for example, turns its host into a fearless, crazed animal by attacking the limbic system, which deals with emotions and memory. Once the limbic system is compromised, the virus turns its attention to the mechanisms in the animals' throat that produce saliva, causing infected animals to foam at the mouth. The virus also inhibits the swallowing mechanism, maximizing the chances infected saliva will spread to another host.
How does the virus "know" to do this? "Evolution by natural selection," says Tyson, explaining that "given enough time, a random mutation will take hold if it enhances the virus' chance of survival." Ironically, it's the victims that keep a virus' "wicked flame" alive as it leaps from host to host, bending them to its will as if it were a sentient being. "We are at the mercy of unseen forces; viruses, microbes, hormones, our very own DNA. Where does the programming end and free will begin, if it ever does at all?"
Elaborating on these points, Tyson turns to insects and animals. Simple behavioral programs are abundant in the animal kingdom; for example, upon their death, bees secrete oleic acid (a "death pheromone") to tell their fellow hive members to remove their corpses from the hive, and geese will instinctively retrieve any egg-like objects that may have rolled away from their nests. While we may detect evidence of spontaneous decision-making in animals, Tyson says, can we identify a source of executive authority in them, or a "soul"? What about human beings?
We don't yet have established parameters for what it means to be "distinctly human," Tyson notes. Plato was one of the first philosophers to put forth a definition: "Man is a featherless biped." Aristotle, a student of Plato's, would later proclaim that man is a social and political animal. Neither of these definitions hold much weight; after all, ants, bees, and termites are also social animals. Underscoring this point, Tyson gives us several examples of animal species that engage in trade and art, use technology and tools, parent their young through adolescence into adulthood, and who enslave and exploit other animals and keep them in captivity. Other animals even show each other affection and tenderness.

It would seem the only thing that separates us from other animals, Tyson ponders, is our "neurotic need to feel 'special.'" Against the backdrop of the Halls of Extinction, featured prominently in previous episodes, Tyson insists that there must be a clear distinction between ourselves and animals that justifies our eating them, wearing them and even bringing an end to their species.
"Is DNA destiny, and if it is, does it have the power to write epic tales of heroism and saintliness?" There's heroism in the way a gazelle will put herself in harm's way to protect her offspring and herd from a cheetah, but there's also heroism in stories from our ancient past, as Tyson illustrates with the story of Ashoka. Five seconds ago on the "cosmic calendar" — approximately 2,200 Earth years ago — the emperor Ashoka's reign of terror over the Indian subcontinent began, marked by his proclivity for torture and extreme violence.
After an exchange with an unnamed Buddhist monk, Ashoka underwent a profound change; having realized the true scope of his power, social welfare became Ashoka's top priority as his idea of "kinship" expanded to include everyone, even animals. He banned the ritual sacrifice of animals and established veterinary hospitals. Ashoka further dug wells, planted trees, built shelters, signed peace treaties with neighboring countries he once warred with, built schools, hospitals and hospices, introduced the education of women and free healthcare for all, and much more.
"Ashoka's dream," Tyson says, referring to his philanthropic pursuits, "grows louder with time." We cut to a scene of a mother with her crying child, who had been born just moments before. We see the child again in the twelfth and penultimate episode of the series, "Coming of Age in the Anthropocene." The opening scene finds us on a placid seashore where Tyson describes life on Earth to the newborn. "We're all very young here," he coos, "new, like you, to the mysteries of the universe." Science, Tyson states, is our birthright and is how we piece together our history.
Setting the stage for this new episode, Tyson recalls our own planet's fiery beginnings when it was hammered by a celestial body the size of Mars, which blasted into space material that became Earth's moon. Earth gradually cooled, forming a crust on its surface that allowed oceans to form. In our planet's infancy, days were much shorter; only about six hours long, notes Tyson. The environment was also toxic and hostile: "Scientists reason that the thick, hazy atmosphere trapped the heat of the Earth and made it scorching hot," Tyson explains.
Amazingly, there were organisms that survived this seemingly uninhabitable environment; these were cyanobacteria that lived deep in the oceans, and "remade" the planet by consuming carbon dioxide and producing oxygen, which in turn consumed the thick methane that enveloped our planet, causing temperatures to drop. Atoms of oxygen then gathered in the sky above our planet and formed ozone molecules. Life on land became possible, and the young Earth's landscape changed drastically as this life began to adapt to its new conditions.
At 11 o'clock on New Year's Eve of the cosmic year, Homo erectus stood up for the first time, freeing its hands and earning the species its name. "They began to move around, to explore, daring to risk everything to get to unknown places. They were brave, and their blood runs in your veins," says Tyson of our ancient ancestors. Some explored Africa and others went on to Europe, and evidence supports the theory the European pioneers would later evolve into Neanderthals. Other H. erectus individuals would go on to Asia and evolve into our hominid cousins, the Denisovans.
Our Neanderthal relatives lived much as we did and did many of the things we consider to be "human," says Tyson. To this day, a few of us even carry some Neanderthal genes; however, some unknown force wiped out the Neanderthals and Denisovans many years ago. Scientists postulate it may have been their complacency that doomed them, as we have evidence showing they never ventured beyond ocean coastlines.
More restless than their cousins the Neanderthals and Denisovans, our Homo sapiens ancestors crossed seas and unforgiving landscapes, changing the land, ocean and atmosphere, leading to mass extinction. The scientific community gave our age a new name, "Anthropocene," from the Greek words for "human" and "recent." Just as the Neanderthals and Denisovans may have doomed themselves, however, early Homo sapiens may have doomed their descendants: us.
Altering our world comes at a great price; a "darkness," Tyson says, has been looming over us as our technology advances and population increases. The invention of agriculture allowed humans to settle on farms and later in cities. The carbon dioxide and methane released from various farming and agricultural techniques increased exponentially as our need for them increased, to sustain ever-growing numbers. In China we began burning coal, which became fuel for foundries, forges and homes.
As harmful to the environment as these were, nothing compared to the damage done by chlorofluorocarbons, or CFCs. Before refrigerators, we kept food items cool and stored them in ice boxes. Later, the ice box was replaced by a gas-powered refrigerator that used ammonia sulfur dioxide as a coolant. However, these chemicals were poisonous and the mechanism would often leak, making them dangerous. The invention of CFCs, a molecule that hadn't existed in nature previously, was so successful it was used in almost everything.
The catastrophic effect CFCs had on ozone was not discovered until the early 1970s, when chemists Mario Molina and Sherwood Rolland, studying the effects rocket fuel had on the atmosphere, found CFCs not only accumulated in the atmosphere, but had already thinned the ozone layer. When UV light hits a CFC molecule, it strips away the chlorine atoms, which then eat away at ozone, the very insulation that makes it possible to live on Earth. Thankfully, the scientists worked tirelessly to warn the world, and global governments heeded their warning; manufacturers stopped producing CFCs, and the ozone has been getting thicker ever since. Our children may even see the damage completely healed.
The episode ends on a harrowing note, another scientists' warning we have yet to heed. Syukuro Manabe was born in rural Japan and took an intense interest in Earth's average global temperature. During the course of his career, he would assemble the evidence he needed to write "Thermal Equilibrium of the Atmosphere with a Given Distribution of Relative Humidity," a paper that predicted the increase of Earth's temperature due to greenhouse gases until it becomes an uninhabitable and toxic environment again, leading to our extinction.
Many still believe the "science is unsettled," however, despite Manabe's correctly predicting the rise in temperature and its effects on our planet. "The scientists warned us," says a remorseful Tyson as we look into our future at life on Earth: lethal outdoor temperatures, global water shortages, wildfires. These ruminations culminate in the striking visual of battered baby bottles littering a dry and barren field, implying the worst for mankind. Tyson ends on a hopeful note, which will carry us into the final episode of the series.
"This doesn't have to be," says Tyson. "it's not too late. There's another hallway, another future we can still have. I promise to get you there; we'll find a way."
"Cosmos" airs on the National Geographic channel on Mondays at 8 p.m. ET/9 p.m. CT and will be reprised on the Fox television network this summer.
The BepiColombo spacecraft headed for Mercury showed off an epic last view of Earth while zooming away from our planet on Friday and Saturday (April 10 and 11).
Footage from the spacecraft shows a crescent Earth slipping away from the structure of the European-Japanese probe, which should arrive in orbit Mercury in 2025. The Earth flyby was one of a series of planetary encounters needed to lose speed for the long journey, a procedure that saves on fuel.
The spacecraft zoomed to as low as 7,900 miles (12,700 kilometers) above our planet, with an altitude roughly 32 times the normal cruising orbit of the International Space Station.
"Images gathered just before closest approach portray our planet shining through darkness, during one of humankind's most challenging times in recent history," wrote the European Space Agency in a statement. Officials had previously urged astronomy enthusiasts to observe novel coronavirus-related "social distancing" guidelines while searching for the spacecraft from their balconies or backyards.
One of the most difficult parts of the flyby involved 34 minutes of darkness for BepiColombo, when it flew through the shadow of Earth. This was the first time the solar-powered spacecraft did not receive sunlight to "power up" instruments and essential equipment since its launch 18 months ago, in October 2018.
To prepare for the darkness, mission operators fully charged the spacecraft's batteries and made sure all components were nice and warm. Social distancing efforts due to the ongoing coronavirus pandemic were in force at the spacecraft mission control center in Darmstadt, Germany, with only limited personnel on site. The effort worked without any problems, ESA added in the same statement.
"It is always nerve-wracking to know a spacecraft's solar panels are not bathed in sunlight. When we saw the solar cells had restarted to generate electrical current, we knew BepiColombo was finally out of Earth's shadow and ready to proceed on its interplanetary journey," Elsa Montagnon, BepiColombo spacecraft operations manager for ESA, said in the statement.
Scientists switched on most of the instruments during the flyby to do scientific measurements of the moon and Earth's magnetic field, ESA added. These observations will serve as a test run for operations at Mercury. BepiColombo scientists will analyze the data in time to make any necessary calibrations for the spacecraft's next flyby, which will be of Venus in October.
ESA marked the maneuver's conclusion by sharing an animation of images captured as the spacecraft flew away from Earth within a day of the flyby, paired with a quote from famous astronomer Carl Sagan. "That receding crescent … 'Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.' - Carl Sagan. Farewell @BepiColombo, and goodnight."

Numerous spacecraft and agency Twitter feeds provided updates on the mission during and after the flyby.
"Dear Earthlings, I'm almost one million km from Earth now and I miss you so much," the @BepiColombo Twitter account said Monday (April 13). "It would make me so happy if you could share any photos you've taken of my flyby on Friday." The account added a link to a Flickr group hosting photos of the flyby taken by amateur photographers tracking the spacecraft's passage.
The animation also caught the attention of some prominent tweeters.
London's Northolt Branch Observatories, which typically studies comets and asteroids during Earth flybys, posted a picture on Twitter showing its view of BepiColombo in the sky. "It was visible at +16.9 mag at the time, in the direction of the constellation Hydra," the tweet on Sunday(April 12) read. A +6 magnitude in brightness is considered the threshold of naked-eye visibility, so +16.9 magnitude is only visible in a large telescope.
Scientific updates about the mission's progress will be available in the coming weeks at @ESA_Bepi, @ESA_MTM and @BepiColombo.
A newly discovered asteroid about the size of a house will zip safely by Earth on Wednesday (April 15), passing just inside the orbit of the moon.
The asteroid 2020 GH2 will pass Earth at a range of about 223,000 miles (359,000 kilometers). The average distance from the Earth to the moon is about 239,000 miles (385,000 km).
Asteroid 2020 GH2 is about between 43 and 70 feet (13-70 meters) wide, or about the size of a detached house, according to data from the Center for Near Earth Object Studies at NASA's Jet Propulsion Laboratory and the agency's Asteroid Watch Twitter account. It was first discovered on Saturday (April 11) and is being tracked by astronomers at several observatories, including the Catalina Sky Survey at Mount Lemmon in Arizona, according to the Minor Planet Center at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts.

Asteroid 2020 GH2 poses no impact risk to Earth during its flyby. While flying inside the moon's orbit sounds like a close shave by an asteroid, there's actually a lot of room.
In a March 31 video shared on Twitter by NASA's Asteroid Watch Twitter account, Kelly Fast of the agency's Planetary Defense Coordination Office demonstrated just how much space is out there. She used a tennis ball as the moon and a basketball as the Earth, placing them 25 feet (7 meters) apart in a hallway — the scale distance between the Earth and moon. At that scale, a huge asteroid like the one that doomed the dinosaurs would be the size of a grain of salt, Fast said.
"Space is pretty big," Fast said in the video, which is part of the NASA At Home project. "A close-approach asteroid is really starting to get close, maybe, when it gets within the distance of the weather satellites." Geostationary weather satellites orbit the Earth at a distance of about 22,000 miles (35,000 km).
That's not to say that near-Earth asteroids don't represent a potential threat to Earth. Scientists with NASA's Planetary Defense Program and around the world regularly observe the skies for new and known asteroids that might pose a danger to Earth.
Any asteroid about 500 feet (140 m) or larger with an orbit that brings it within 4.7 million miles (7.5 million km) of Earth is classified as a potentially hazardous asteroid, NASA officials have said. As of 2019, scientists have discovered about 19,000 near-Earth asteroids, with about 30 newfound asteroids added each week.
And if you thought the house-sized asteroid 2020 GH2 sounds big, NASA is gearing up for an even larger asteroid to fly by on April 29. On that day, the potentially hazardous asteroid 1998 OR2 will fly by Earth at a safe distance of 3.9 million miles (6.2 million km).
Correction: This story was updated on April 15 to reflect that NASA's Asteroid Watch is an outreach arm online on Twitter and this website and not a planetary defense program. The agency's Planetary Defense Program is overseen by the Planetary Defense Coordination Office at NASA headquarters in Washington, D.C.
De helderste supernova draagt de (abstracte) naam SN2016aps en vond zo’n 3,6 miljard lichtjaar van de aarde plaats. “SN2016aps is om verschillende redenen spectaculair,” aldus astronoom Edo Berger. “Hij is niet alleen helderder dan elke andere supernova die we ooit hebben gezien, maar hij heeft ook verschillende eigenschappen en kenmerken die ’m erg zeldzaam maken in vergelijking met andere explosies van sterren in het universum.”
Het onderzoeksteam identificeerde de supernova SN2016aps voor het eerst in 2016. Daarvoor gebruikten ze de gegevens van de Pan-STARRS, een stel van twee telescopen. Al snel volgde een vierjarig vervolgonderzoek waarbij de energie-uitstoot nauwgezet bestudeerd werd.
Wat bleek? De explosie van de ster was tien keer zo krachtig als een supernova van normale grootte. Bij de gemiddelde supernova is slechts 1 procent van de totale energie-uitbarsting zichtbaar. Maar de SN2016aps straalde ongeveer 50 procent van zijn energie uit. “De intense energie-uitstoot van deze supernova wijst op een zware ontplofte ster, die bij zijn geboorte minstens 100 keer zoveel massa had als onze zon,” zegt Berger.
Uiteindelijk kwamen de onderzoekers tot de conclusie dat SN2016aps wellicht is ontstaan door de samensmelting van twee zware sterren.

Linda Moulton Howe Explores Area 29, White Sands Missile Base
COAST TO COAST AM – Linda presented her interview with researcher Ryan Wood, who revealed information about a secret facility within the White Sands Missile Range in New Mexico referred to as “Area 29.”
Wood and his father Robert received documents and photos referring to this facility beginning in the mid-1990s, and recently hired a remote viewer he referred to as “Sky Arrow” to report on any impressions that could be deduced from the material.
According to Wood, the viewer first said that the “target makes me nervous,” but went on to describe a facility that housed space vehicles, UFOs, and “experimental energy research for deep space propulsion vehicles.” From these impressions, Wood concluded that the facility is “tapping into something that modern, open science doesn’t know or understand.”
For a long time, many experts believed that there was no sound in space because it is a vacuum, but sound does exist in the form of electromagnetic vibrations, you just need the right tools to be able to hear it. NASA scientists with the Van Allen Probes mission were able to record these sounds, and have given them different classifications.
To make the recordings, scientists used the “Waves instrument,” which is part of the Electric and Magnetic Field Instrument Suite and Integrated Science project, also known as EMFISIS. EMFISIS is an instrument suite on the Van Allen Probes, and it is sensitive to both electric and magnetic waves.
Accord to the NASA blog, “It probes them with a trio of electric sensors as well as three search coil magnetometers, which look for changes in the magnetic field. All instruments were specifically designed to be highly sensitive while using the least amount of power possible.”
Scientists were recording these waves because they want to learn more about how space works.
“These plasma waves knock about high-energy electrons speeding around Earth. Some of those freed electrons spiral earthward, where they interact with our upper atmosphere, causing auroras, though others can pose a danger to spacecraft or telecommunications, which can be damaged by their powerful radiation,”according to NASA.
Below are some of the descriptions that NASA gave for the sounds:
Juno Captures the “Roar” of Jupiter:NASA’s Juno spacecraft has crossed the boundary of Jupiter’s immense magnetic field. Juno’s Waves instrument recorded the encounter with the bow shock over the course of about two hours on June 24th, 2016.
Plasma Waves:Plasma waves, like the roaring ocean surf, create a rhythmic cacophony that, with the EMFISIS instrument aboard NASA’s Van Allen Probes, we can hear across space.
Sounds of a Comet Encounter:During its February 14th, 2011, flyby of comet Tempel 1, an instrument on the protective shield on NASA’s Stardust spacecraft was pelted by dust particles and small rocks, as can be heard in this audio track.
If you are into that sort of thing, you can also purchase entire recordings like this from Amazon, but they are also available widely on streaming services like SoundCloud as well.

Energy Entity Recorded Over North Carolina Darting About, Video, April 14, 2020, UFO Sighting News.
Date of sighting: April 14, 2020 Location of sighting: Raleigh, North Carolina, USA Source: MUFON I have heard reports of a sphere being seen around the world. Videos and photos have been uploaded all week. From the shape of this object in the photos above...I would say this is not a perfect sphere and looks to have over ten right angles on it. Planets dont have right angels. They are round. Also the description of this object darting about also falls into place with other reports. This is an awesome video. This is not a UFO so much as an energy being...and entity that is of the highest level of assertion for any species. Very rare, very real. Scott C. Waring Eyewitness states:
Visual bright orb brighter than typical star. Not an aircraft . Potentially thought was a drone however it aas above and well beyond cloud cover altitude. Moved erratically at points and changed locations. Too large for drone and outside all flight paths of rdu. Moved out of sight after 30 min.

Alien Artifact On Surface Of Mars In Rover Photo, Video, UFO Sighting News.
Date of discovery: July 12, 2015
Location of discovery:Mars, Sol 1037
Original link: Deleted by NASA
Here is an old discovery I have never seen before. It was found by Youtuber IC Devices and shows some ancient artifact on the surface of Mars. The object in question is folded and has three layers with a baseball size sphere sitting on the top layer. The objects color looks different from the color of its surroundings. It looks grey, metallic in appearance. Another strange thing is the original link to this was deleted by NASA. This is a remarkable find, and had this been discovered in an ancient Aztec or Mayan dig site...there would be no question about it being made by intelligent beings. I hope this discovery inspires you to start searching and reporting discoveries of your own. We learn together as we teach each other.
