Two teams of astronomers using ESA’s XMM-Newton space telescope have observed repeated outbursts of light from inactive black holes that partially destroy stars again and again. This discovery is unexpected, since outbursts of black holes usually appear only once when a black hole consumes a star.
Hidden supermassive black hole Astronomers can “see” a hidden supermassive black hole when a star rotates towards it as it approaches. The star is torn apart by strong tidal forces, forming a disk of stellar debris from which the black hole feeds. Energetic X-rays, ultraviolet, optical, and radio light can be detected during this process known as a tidal disturbance event. The black hole can never be seen. His presence is assumed from the behavior of things around him; in this case, the stars are eaten alive. Tidal disturbance events occur in a bright light called the Flare, which usually lasts for a few months and during this time the black hole devours the star. However, XMM-Newton observed two new flares with strange behavior. These flares glow repeatedly in X-rays and ultraviolet light after the first explosion, suggesting that the stars were not completely destroyed during their initial encounter with the black holes.
managed to observe the final moments of a star’s life as it was swallowed by a black hole.Using the Hubble Space Telescope, astronomers have recorded in detail the final moments of a star when it is engulfed by a black hole.existence of its first exoplanet , which is almost the same size as Earth, is rocky, and is 41 light years from Earth. With the US space agency’s Hubble Space Telescope, astronomers were able to see when the star got close enough, causing the black hole’s gravitational force to tear it apart and devour its gases. These types of events are called “disruption events.” and as they occur, the black hole spews out intense radiation. They lie in wait until a hapless star passes by. However, Hubble can’t photograph the event up close, as it passed nearly 300 million light-years away of the in the center of the galaxy ESO 583-G004.UU) and the results were presented at the meeting of the American Astronomical Society.
