Detecting black holes

Scientists from the US Aeronautics Agency (NASA) have observed a giant black hole devouring a star in a galaxy of distant galaxies 4 billion light-years away from Earth.

This finding, published Dec. 5, shows for the first time that telescopes can be seen in detail in a mysterious phenomenon in the universe.

In the past two years, American scientists have used telescopes to track interesting phenomena in the universe, and discovered a " resident " star in the galaxy's constellation of Bootes with a black hole. Giant torn into pieces.

With the telescope " Exploring the Galaxy's development ," scientists discovered an ultraviolet light emanating from the center of an elliptical galaxy band of the Bootes constellation that was far away. Astronomer Suvi Gezari of the California Institute of Technology in Pasadena (USA) said that in fact, this light emitted from a star was " torn " and swallowed into a black hole. This is a very rare phenomenon, only 10,000 years before a star is swallowed by a black hole.

Scientists hope this discovery will help them better understand black holes, an object with such mass and gravity that even light cannot escape. Giant black holes are usually located in the center of the galaxy. The Milky Way, the " home " of the Solar System, also has a giant black hole in the middle and inactive.

Scientists continue to use the telescope to observe the process of ultraviolet light (emitted from a star) fading away and disappearing in the black hole.
