Black hole dismembers and eats a large planet

Astronomers M. Nikołajuk and R. Walter caught a black hole in the act of destroying and consuming part of a large planet or small brown dwarf. This event involved a supermassive black hole located in a relatively nearby galaxy, and emitted a burst of intense X-ray light that fluctuated over a short time span, then faded.

Typically, as matter falls onto a black hole at the center of a galaxy, it forms an accretion disk, a rotating region of material that heats to very high temperatures. The result is often strong emissions in gamma rays and radio light, with the output fluctuating only slightly.
