The Mystery of the Naked Black Hole (sciencemag.org)

sciencehabit writes: Most, if not all, galaxies have supermassive black holes at their centers surrounded by dense clouds of stars. Now, researchers have found one that seems to have lost almost its entire entourage. The team, which reported its find at the annual meeting of the American Astronomical Society, says it doesn't know what stripped the stars away. But it has put forward a tantalizing possibility: The object could be an extremely rare medium-sized black hole, which theorists have predicted but observers have never seen.

A "naked singularity" is usually what people call a black hole without an event horizon, an object that's pretty important in theoretical physics. Calling something a "naked black hole" is kind of confusing. https://en.wikipedia.org/wiki/...
