Astronomers have discovered an invisible black hole with a mass over hundred thousand times of the Sun around the centre of the Milky Way.

A team of astronomers led by Tomoharu Oka, a professor at Keio University in Japan, found an enigmatic gas cloud, called CO-0.40-0.22, which is only 200 light years away from the centre of the Milky Way. This cloud has surprisingly wide velocity dispersion. The team noticed this mysterious feature with two radio telescopes. A recent study already suggested that there are 100 million black holes in the Milky Way Galaxy but X-ray observations have only found dozens so far.

This discovery might be the first detection of an intermediate mass black hole (IMBH).
