Astronomers have seen the largest explosion yet in space
Astronomers have observed the largest explosion yet in space that we're aware of, a years-long event involving a supermassive black hole estimated to be one billion times more massive than the Sun that continues to rage.The eruption, codenamed AT2021lwx, was first recorded by ground-based telescopes - the Zwicky Transient Facility in California, and the Asteroid Terrestrial-impact Last Alert System in Hawaii - in 2020.
Astronomers capture largest cosmic explosion ever witnessed
It started as an unremarkable flicker in the night sky.But closer observations revealed that astronomers had captured the largest cosmic explosion ever witnessed, an event thought to have been triggered by a giant cloud of gas being gobbled up by a supermassive black hole.The flare-up, traced to 8bn light years away, is more than 10 times brighter than any known supernova and has so far lasted more than three years, making it the most energetic explosion on record.
The galaxy in which we live in- The Milky Way (Image: Reddit) While observing the night sky in a low bortle, you may be able to see a fuzzy band of light stretching across the sky.What you are looking at is the plane of our galaxy- The Milky Way.Our galaxy is home to an estimated 400 billion stars, with most younger stars lying in the centre of the plane of the galaxy- in the spiral arms where most of the galaxy's dust and gas, which clump together to create sites of star formation, is concentrated; relatively older stars are generally found in the outer areas of the plane- though some can be found in 'halos' of globular clusters around the outside of the Milky Way.
The Biggest Explosion in the Cosmos Just Keeps Going
It's a dog-eat-dog cosmos.Not two weeks ago, on May 3, astronomers reported observing a star that was in the process of swallowing one of its own planets.Just two days earlier, another team had described black holes that were ripping stars apart and consuming them in a process known as tidal disruption event, or T.D.E.

No, physicists didn't make a real wormhole. What they did was still pretty cool
Wormholes are a classic trope of science fiction in popular media, if only because they provide such a handy futuristic plot device to avoid the issue of violating relativity with faster-than-light travel.In reality, they are purely theoretical.Unlike black holes-also once thought to be purely theoretical-no evidence for an actual wormhole has ever been found, although they are fascinating from an abstract theoretical physics perceptive.
Black Hole In "Hyper-Feeding Frenzy" Chews Through Stars and Shoots Its Leftovers Towards Earth
Cosmic Combine Using the Very Large Telescope (VLT), scientists have witnessed a black hole more than 8.5 billion light years away gorging on a star - the farthest distance at which astronomers have ever observed such an event.In fact, they were only able to spot the grisly feeding in visible light because leftovers of the kill were ejected via a jet that happened to be pointed right at Earth, leading to the publication of two separate studies in the journals Nature and Nature Astronomy.
Astronomers capture black hole gobbling up a star in a "hyper-feeding frenzy"
Earlier this year, astronomers picked up an unusually bright signal in the X-ray, optical, and radio regimes, dubbed AT 2022cmc.They've now determined that the most likely source of that signal is a supermassive black hole gobbling up a star in a "hyper-feeding frenzy," shooting out jets of matter in what's known as a tidal disruption event (TDE).
Bright light from black holes caused by particle shock waves
Scientists have reported a "huge leap forward" in the understanding of light and other electromagnetic radiation emitted by black holes using NASA's newly deployed $188m space telescope IXPE.Beams of electrons smash into slower-moving particles causing a shock wave which results in electromagnetic radiation across frequency bands from X-rays to visible light, according to a research paper published in Nature this week.

Black holes can't trash info about what they swallow-and that's a problem
No information about the original material that created the black hole survives.Whether the black hole was formed from dying stars or squashed kittens, it doesn't practically matter.If I tell you the mass, electric charge, and spin (i.e., angular momentum) of a black hole, we're done.Just three numbers-that's all it takes to completely, unequivocally, 100 percent describe a black hole in general relativity.In the traditional, classical view of black holes, all this business about information is not a problem at all.
On Wednesday, September 14 at 19:30 GMT: A black hole is believed to be the most extreme environment in the universe an area in space where the force of gravity is so intense, not even light can escape.
