CTOnews.com, January 15 (Xinhua) although humans have been able to observe black holes, our understanding of these extreme objects is still limited. Because the black hole is covered by the event horizon, which prevents us from exploring the black hole, it is impossible to observe the internal structure of the black hole.

If black holes can devour everything, including stars and light, where will these materials eventually go?

NASA captured a rare image of a black hole 300 million light-years away in the form of a star eater, crushing and stretching a passing star, eventually creating a gas cloud the size of the solar system in the universe.

Although the latest James Weber photo is more topical, it was actually taken by the Hubble Space Telescope. With luck, the star collapses closer to the telescope than usual. As a result, astronomers can observe the event for a long time, which enables them to capture more data.

The black hole was discovered by the Hubble Space Telescope in March last year, and NASA reported the results at an astronomical conference in Seattle this month. NASA officials call such events "tidal destruction / tidal disintegration", which is simply the story of an unsuspecting star encountering a black hole while roaming the universe.

At present, the black hole is still one of the most powerful beings in the known universe, its gravity is unimaginable, even light can not escape. A typical black hole has a mass of about 100 suns, and some supermassive black holes can even withstand billions of suns.

CTOnews.com query found that the largest known black hole in the Milky way galaxy is Amari Sagittarius, which has a mass equivalent to 4.3 million suns, while the largest black hole detected so far is Phoenix A, which is located in the center of the Phoenix cluster, about 5.7 billion light-years from Earth, with a mass comparable to 100 billion suns.

Judging from the images released by NASA, the end result of this event is that the star debris is pulled into a "doughnut" by the surrounding black hole, which NASA officially named AT2022dsb.

Currently, the star is about 300 million light-years from Earth and is located at the core of the ESO 583-G004 galaxy. Despite their unfathomable distances, astronomers can study AT2022dsb by analyzing the ultraviolet rays emitted by stars through the range of light emitted by their constituent elements, such as carbon and hydrogen.

It is reported that the event was first discovered on March 1, 2022 by the supernova all-sky automatic Sky Survey (ASAS-SN) program of astronomers at Ohio State University. NASA explained that AT2022dsb is closer to Earth than other similar events, causing astronomers to have a longer observation period.

Most importantly, longer time will enable scientists to use ultraviolet light to understand the "doughnut", which is more detailed than the results usually studied by X-rays. this can provide astronomers with more information about the elements in the event.
