Astronomers see a black hole swallowing a star

scientists of NASA managed to observe the last moments of the life of Estrella While being swallowed by a black hole.

with him Hubble Space Telescope At the US space agency, astronomers were able to see when the star got close enough that the black hole’s gravitational pull pulled it apart and devoured its gas.

such events are calledtidal disruption eventsAnd as soon as they are, the black hole spews out intense radiation.

However, Hubble cannot observe this event closely, as it has passed almost 300 million light years away from tierra, in between Galaxy ISO 583-G004.

Nevertheless, the collision was close enough to our planet and bright enough for scientists to make ultraviolet spectroscopy longer than usual. It is a process that involves using the ultraviolet sensitivity of a telescope to study the emitted light, which is composed of hydrogen, carbon and other gases.

From this they were able to interpret the data on stellar dust swirling around the hole. Thanks to this, they determined that together, the tidal disruption event had the same shape as our Solar System.

Likewise, with this they managed to create an animation that shows what happened.

According to NASA, in each galaxy universe having a dormant supermassive black hole at its center, around which only tidal disruption events occur every 100 thousand years. So far, astronomers have detected only about 100 using various telescopes.
