Chinese astronomers report new findings regarding the central region of a nearby galaxy known as NGC 3319. The researchers found an active intermediate-mass black hole candidate residing in the center of this galaxy. The ...
A stellar mass black hole is a compact object with a mass greater than three solar masses. It is so dense and has such a powerful force of attraction that not even light can escape from it. They cannot be observed directly, ...
