‘Needle in a haystack’ black hole discovered in neighboring galaxy

Scientists have spotted an example of a black hole that should be extremely common but is quite difficult to find.

The challenge of discovering what astronomers call dormant black holes comes from the fact that these objects are not actively feeding on matter like gas, dust or stellar material stripped from a companion star. With no feeding, these black holes don’t blast out X-rays, which scientists use to spot typical black holes. The new discovery could have ramifications for understanding how stars collapse at the end of their lives, according to the researchers.
