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

Researchers have seen an example of a black hole that should be extremely common, but which is quite difficult to find.

The challenge of discovering what astronomers call dormant black holes comes from the fact that these objects do not actively feed on matter such as gas, dust or stellar material removed from a companion star. Without feeding, these black holes do not emit X-rays, which scientists use to detect typical black holes. The new discovery may have implications for understanding how stars collapse at the end of life, according to researchers.
