Astronomers catch a black hole shredding a star to pieces

22 October 2015 Astronomy Now

When a star comes too close to the intense gravity of black hole, the resulting tidal forces can rip the star apart. In these so-called tidal disruptions, some of the stellar debris is flung outward at high speeds, while the rest falls toward the black hole, causing a distinct X-ray flare that can last for years. A team of astronomers has observed a tidal disruption event in galaxy PGC 043234 that lies about 290 million light-years from Earth.
