NASA Astronomy Picture of the Day 4 May 2023: Supermassive Black Hole in Messier 87 Galaxy

[ad_1] The Event Horizon Telescope, which included a collaboration of 8 telescopes around the world in 2017, captured the first ever image of a supermassive black hole at the center of a galaxy known as Messier 87. The supermassive black hole is engulfing huge amounts of gas, and that material forms what scientists call an accretion disk. The gas in the disk can heat up to millions of degrees Fahrenheit due to the gas being so dense.Today's NASA Astronomy Picture of the Day is a snapshot of the supermassive black hole at the center of Messier 87. Messier 87 is a supergiant elliptical galaxy located about 55 million light-years away towards the constellation of Virgo. Alongside the black hole, relativistic jet blasting from the galaxy's central region can be observed. This is due to ioni...

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...

Amazing discovery! Event Horizon Telescope captures amazing gas bubble

[ad_1] Astronomers have discovered a hot gas bubble swirling around a supermassive black hole known as the Sagittarius A*. Did you know that there is a black hole located at the center of the Milky Way Galaxy? Nearly 26,000 light years away at the center of our Milky Way Galaxy is Sagittarius A*, a supermassive black hole which could potentially one day swallow the whole Milky Way Galaxy. The first image of this supermassive black hole was captured by the Event Horizon Telescope in May. The supermassive black hole has huge amounts of gas around it. Now, astronomers have spotted a hot gas bubble swirling around the supermassive black hole. The discovery was made with the help of the Atacama Large Millimeter/submillimeter Array (ALMA) located in the Antofagasta Region of the Atacama ...
