Light echoes reveal supermassive black holes eating stars

17 September 2016 Astronomy Now

When a star passes within a certain distance of a black hole, the stellar material gets stretched and compressed as the black hole swallows it, briefly releasing an enormous amount of energy as a flare. Astronomers have now observed infrared light echoes from these “stellar tidal disruption” events reflected by dust encircling a black hole.


High-speed flare observed from supermassive black hole eating star

An international team of astrophysicists has for the first time witnessed a black hole swallowing a star and ejecting a flare of matter moving at nearly the speed of light. The scientists tracked the Sun-sized star in the galaxy PGC 43234 some 300 million light-years away as it shifted from its customary path, slipped into the gravitational pull of the supermassive black hole and was sucked in.
