Miracle! James Webb Telescope discovers OLDEST black hole in the universe

[ad_1] Black holes are extremely dense regions of space formed by the collapse of giant stars at the end of their life cycle. They are places in space where the pull of gravity is so strong that nothing can escape, not even light. According to NASA, black holes can be differentiated into two, depending on their mass. The first is a Stellar Black Hole which is formed from a single star. The other is a Supermassive Black Hole which forms due to merging of other black holes.Although black holes have been captured before by several space and ground-based telescopes, the James Webb Space Telescope (JWST) has just discovered a stunning image of the black hole, one which lets us peek back in time. Oldest black hole everThe supermassive black hole, discovered by JWST, has a mass 10 times that o...

Scientists unveil new and improved ‘skinny donut’ black hole image

[ad_1] The 2019 release of the first image of a black hole was hailed as a significant scientific achievement. But truth be told, it was a bit blurry - or, as one astrophysicist involved in the effort called it, a "fuzzy orange donut."Scientists on Thursday unveiled a new and improved image of this black hole - a behemoth at the center of a nearby galaxy - mining the same data used for the earlier one but improving its resolution by employing image reconstruction algorithms to fill in gaps in the original telescope observations. Hard to observe by their very nature, black holes are celestial entities exerting gravitational pull so strong no matter or light can escape. The ring of light - that is, the material being sucked into the voracious object - seen in the new image is about half t...

First image of a black hole gets a makeover with AI

[ad_1] The first image of a black hole captured four years ago revealed a fuzzy, fiery doughnut-shaped object. Now, researchers have used artificial intelligence to give that cosmic beauty shot a touch-up.The updated picture, published Thursday in the Astrophysical Journal Letters, keeps the original shape, but with a skinnier ring and a sharper resolution. The image released in 2019 gave a peek at the enormous black hole at the center of the M87 galaxy, 53 million light-years from Earth. A light-year is 5.8 trillion miles. It was made using data gathered by a network of radio telescopes around the world, showing swirling light and gas. But even with many telescopes working together, gaps remained in the data. In the latest study, scientists relied on the same data and used machine lear...

Hubble Telescope records dying moments of a star being eaten by Supermassive black hole

[ad_1] The final moments of a star before being destroyed by a black hole have been recorded by the Hubble Space Telescope. A black hole is a place in space where the pull of gravity is so strong that nothing, including light, can escape. It is an extremely dense region of space formed by collapse of a giant star at the end of its life cycle. A supermassive Black Hole forms due to merging of black holes. The biggest black hole is a Supermassive black hole which resides in the center of galaxies and is capable of engulfing everything in its way. These black holes have masses that are more than 1 million suns together. Now, scientists have discovered a star actually being eaten by a supermassive black hole. Scientists, using the Hubble Space Telescope have recorded the final moments ...

Hubble finds hungry black hole twisting captured star into donut shape

[ad_1] Black holes are gatherers, not hunters. They lie in wait until a hapless star wanders by. When the star gets close enough, the black hole's gravitational grasp violently rips it apart and sloppily devours its gasses while belching out intense radiation. Black holes are gatherers, not hunters. They lie in wait until a hapless star wanders by. When the star gets close enough, the black hole's gravitational grasp violently rips it apart and sloppily devours its gasses while belching out intense radiation. Astronomers using NASA's Hubble Space Telescope have recorded a star's final moments in detail as it gets gobbled up by a black hole. These are termed 'tidal disruption events'. But the wording belies the complex, raw violence of a black hole encounter. There is a balance be...

Behind the Amazing Photo of the Milky Way Galaxy’s Very Own Black Hole

[ad_1] Sagittarius A*, the supermassive black hole at the center of our galaxy, has fascinated cosmologists for years. Now we’ve got pics. One reason scientists are so fascinated with black holes is that they grab hold of the fabric of time and space, slowing time to a crawl as matter swirls toward a point of no return. The fact that black holes play tricks with time was what captured the imagination of Lia Medeiros, a postdoctoral fellow at the Institute for Advanced Study, and part of the team that used an array of eight telescopes to create the first image of matter swirling around the supermassive black hole at the center of the Milky Way. She was still a high school student when she first read that black holes distort...
