Massive black hole spotted without galaxy

"In a strange reversal, astronomers have detected a massive black hole but can find no traces of the surrounding galaxy that should be feeding it.

At the center of most large galaxies, our own Milky Way included, are extremely dense black holes that have masses hundreds of millions times that of the Sun.

Called quasars, these massive black holes are the most radiant objects in the universe, outshining even the brightest galaxies. While the black holes themselves are undetectable, friction and heat from the swirling matter they ingest emit huge amounts of radiation that can be detected by radio telescopes."
