Astronomers in Awe of Terrifying "Eye of Sauron" That's Pointed Straight at Earth
Thankfully, the object, unimaginatively dubbed "PKS 1424+240," is located roughly 7.4 billion light-years away and likely won't pose much of a danger.
But that hasn't stopped a group of excited astronomers from renaming it: the "Eye of Sauron," the symbol adopted by the Dark Lord in JRR Tolkien's epic "Lord of the Rings" trilogy.
A new image of the object was recently unveiled, revealing a bright, hot center with cosmic waves spinning around it, spewing a jet of plasma straight at Earth — as if one was staring right into the Eye of Sauron.
The scientists published the image in a new paper in the journal Astronomy & Astrophysics, detailing how they unraveled a mystery at the center of PKS 1424+240, which appears bright from matter falling into the ravenous maw of the black hole.
PKS 1424+240 is specifically a blazar, a type of galactic nucleus that shoots jets of plasma from its center at almost the speed of light straight towards Earth. Quasars are essentially the same thing, but are not oriented towards our home planet.
What's curious about PKS 1424+240, or the Eye of Sauron, is that it emits copious amounts of gamma rays and neutrinos and is considered the brightest neutrino-producing blazar in the universe, at least as far as we know.
But PKS 1424+240 also has cosmic jets that move "sluggishly," according to a statement from the Max Planck Institute for Radio Astronomy, where part of the research was conducted. This goes against a commonly held assertion that only fast-moving jets can produce bright objects.
After poring over years of observation from radio telescopes and studying the image, astronomers concluded that they are looking at a kind of "optical illusion."
Having the cosmic jets pointing directly at Earth increases the brightness of the blazar, while they also appear slower than they actually are.
"This alignment causes a boost in brightness by a factor of 30 or more," said Jack Livingston, study co-author and researcher at Max Planck in a statement. 'At the same time, the jet appears to move slowly due to projection effects — a classic optical illusion."
What's also neat is that the astronomers were able to recreate what the blazar jet's magnetic field may look like — a spiral, or a toroidal doughnut.
Besides plumbing the mysteries of the blazar, the study could help astronomers better understand the relationship between the shape of these cosmic jets and their magnetic fields, further shedding light on the nature of supermassive black holes.

Hubble reveals new details about alien comet 3I/ATLAS
Hubble has captured the sharpest images to date of interstellar object 3I/ATLAS, revealing new details about this icy alien traveller. The discovery of the third interstellar object passing through our solar system has the astronomy community fairly excited. Given the limited amount of time we have to observe 3I/ATLAS before it leaves our solar system, never to be seen again, astronomers want to find out as much as they can about it, while they have a chance. To this end, increasingly more powerful telescopes are being turned towards 3I/ATLAS. Ground-based observatories have been delivering images, so far, giving researchers a chance to make educated guesses at the nature of the object and how big it is. On July 21, astronomers got their first look at 3I/ATLAS using the Hubble Space Telescope. Hubble's first image of Comet 3I/ATLAS. The streaks in the background are distant stars, drawn out into lines as the telescope tracked the moving object. According to NASA, a blue filter was used for these observations. (Image: NASA, ESA, David Jewitt (UCLA); Image Processing: Joseph DePasquale (STScI)) With 3I/ATLAS currently surrounded by a cloud of dust, ice, and gas (its 'coma'), the solid nucleus of the comet cannot be seen, even by Hubble. However, these observations give astronomers a better estimate of the size of this alien object, simply by comparing what they're seeing with the behaviour of 'home grown' comets. From ground observatories, based on its brightness, the original best estimate for the size of its nucleus was anywhere from 10-20 kilometres in diameter. New data from Hubble has significantly reduced that, putting an upper limit on the comet's size of 5.6 kilometres wide. That's still substantially larger than both 2I/Borisov and 1I/'Oumuamua, which were estimated at being roughly 500 metres wide and 100 metres wide, respectively. Still, the researchers who took the Hubble observations believe it's possible 3I/ATLAS's nucleus could be as small as just 320 metres across. Hubble's view of 3I/ATLAS. The comet is travelling from left to right in this field of view, with the Sun generally located off the right edge of the image. (Image: NASA, ESA, David Jewitt (UCLA); Image Processing: Joseph DePasquale (STScI)) The image captured by Hubble also reveals more detail, confirming 3I/ATLAS's cometary nature. As seen above, the solid nucleus is located within the bright region on the left side of the fuzzy 'teardrop'. The diffuse region on the right appears to be a plume of dust being ejected from it, as sunlight warms the nucleus' surface. Comets produce tails of dust and ionized gas, which both generally point away from the Sun. However, this kind of dust plume being generated in the direction of the Sun is apparently common in comets when they are farther out in space and first begin to feel the Sun's heat. Additionally, according to NASA, the researchers report seeing the hints of a dust tail streaming away from the nucleus. We still have roughly a month before most telescopes will lose sight of comet 3I/ATLAS as it passes around the other side of the Sun. At that time, orbiters around Mars might get a better look. Then, starting in early December, astronomers will pick up observations of it again, and have at least until early 2026 before it gets too far away to see. "Observations from other NASA missions including the James Webb Space Telescope, TESS (Transiting Exoplanet Survey Satellite), and the Neil Gehrels Swift Observatory, as well as NASA's partnership with the W.M. Keck Observatory, will help further refine our knowledge about the comet, including its chemical makeup," says NASA.

The Secret To Life On Mars Could Be Cosmic Rays, According To This New Study
Life on Mars sounds like something from a "Doctor Who" episode. But a study published in the International Journal of Astrobiology challenges the science fiction notion of that idea. The research points out that Mars' atmosphere is thin and the planet lacks a magnetic field, therefore, it is constantly bombarded with powerful radiation from space, specifically, galactic cosmic rays. These high-energy particles come from outside of our solar system and are typically considered destructive as they can damage DNA and harm living cells. However, the publication's research suggests that under the right conditions, this same radiation might help life survive instead of destroying it. Already, Earth hosts a microbe that survives entirely on radiation. Deep in a South African gold mine, scientists discovered an organism that powers its metabolism using radiation-driven chemistry, without any sunlight at all. The research raises the question of whether similar life could be hiding beneath the surface of Mars, where cosmic rays interact with rock and ice in a way that could support life. Read more: What's Happening To Earth Right Now Can't Be Explained By Climate Models How Cosmic Rays Might Support Life On Mars When cosmic rays hit rocks or ice, they set off a chain reaction called radiolysis. This process splits water and other molecules into smaller parts, creating energy-rich compounds like hydrogen and oxidants. These are the kinds of chemicals that simple microbes could use as food. The study introduces a new idea referred to as the radiolytic habitable zone (RHZ). These are regions below the surface where cosmic ray–driven reactions might provide enough energy to support microbial life. Using simulations, the researchers estimated how deep this zone might go on Mars, as well as Jupiter's moon Europa and Saturn's moon Enceladus. The theory is that these RHZs could support simple, radiation-powered life forms in areas that are protected from the harsh surface conditions. However, this idea is still theoretical, so we are not setting up a base on Mars just yet. Researchers acknowledge that the models don't account for how temperature variations might affect underground chemistry, or what kinds of organic molecules can actually form there. Of course, because Earth doesn't get much cosmic ray radiation due to its protective atmosphere and magnetic field, there are no real-world examples of life evolving under these conditions. Where We Might Be Able To Live On Mars If the researchers' theory is right and life powered by cosmic rays does exist on Mars, there are a couple of promising places to look. These are beneath Mars' polar ice caps. The north pole is called Planum Boreum and the south pole is called Planum Australe. These massive ice caps on Mars are mostly made of water ice and a seasonal layer of carbon dioxide ice, also known as dry ice. They offer a unique environment where life might be shielded from the surface radiation while still getting enough cosmic ray exposure underground to fuel radiolytic chemistry. So far, no mission to Mars has explored these polar regions directly. However, future missions are in progress. The European Space Agency's ExoMars mission is set to launch in 2028, and NASA's Mars Life Explorer is planned for the 2030s. These will include drills capable of reaching about six feet below the surface, theoretically deep enough to reach the RHZ and test for possible signs of life. These two future missions, if successful, will be critical in discovering if the theory in the International Journal of Astrobiology has merit. While the idea is intriguing, there is still a long way to go before humans could potentially have their own settlements in other regions of our solar system. Read the original article on BGR.

Six-Planet Parade On Sunday: When And Where To See It By A Crescent Moon
Early risers are this week being treated to the sight of a 'planet parade' in the eastern sky before sunrise featuring Saturn, Jupiter, Venus, Mercury and the moon. Best seen about an hour before sunrise on Sunday, Aug. 17, Saturn will be visible in the south, with the moon high above the east, accompanied by bright planets Jupiter and Venus below. Mercury could also be glimpsed below Venus in the gathering light of dawn. Uranus and Neptune will also be in the sky but not visible to the naked eye. From Aug. 17–21, a spectacular 'planet parade' (also called an alignment) will feature the moon and six planets. getty About an hour before sunrise, a 36%-lit waning crescent moon will shine high above Jupiter and Venus in the eastern sky. Mercury will hug the eastern horizon and be easier to spot closer to sunrise, though it's on the cusp of reaching its farthest position from the sun from Earth's point of view. Jupiter will be the highest of the visible planets, while Venus will blaze brightest between Jupiter and Mercury. Saturn will be visible in the southern sky. The ringed planet is currently brightening as it nears its annual bright 'opposition' on Sept. 21, when Earth will be between Saturn and the sun. The highlight of this week's 'planet parade' will arguably come on Wednesday, Aug. 20, when a slender crescent moon will shine very close to a brilliant Venus. The next 'planet parade' isn't until October 2028, when five planets will be visible together before sunrise. Sunday, August 17: A 'Planet Parade' Stellarium Jupiter, the largest planet in the solar system, is hard to miss in this morning's sky. It will spend the rest of the year rising higher into the morning sky and won't come to a bright opposition this year. It's an occasional consequence of its 13-year orbit around the sun. Jupiter will next be at its biggest, brightest and best on Jan. 10, 2026. Through binoculars or a telescope, you can glimpse some of its largest moons — Io, Europa, Ganymede, and Callisto — lined up like tiny stars. The 'planet parade' will look much the same on Monday, Aug. 18, when a slimmer 26% crescent moon will glow near Venus and Jupiter. On Tuesday, Aug. 19, Mercury will be at its highest in the morning sky as the moon wanes to 16%-lit and forms a curve with Venus and Jupiter. On Wednesday, Aug. 20, a 9%-lit crescent moon will appear very close to Venus, with Mercury below and Jupiter above in what is perhaps the highlight of the week-long event. Come Thursday, Aug. 21, the slender 4%-lit waning crescent moon will be beneath Jupiter and Venus, close to Mercury. What's Next In The Night Sky With the 'planet parade' over on Aug. 22 as Mercury sinks, Saturn and Jupiter will gradually brighten as Venus begins to fade. Before sunrise on Aug. 31, Venus will be positioned within the Beehive Cluster, a dense cluster of stars that looks great through binoculars.
