Gaia BH1

Post by brian livesey »

The closest black hole yet discovered was announced yesterday. The object lies at a distance of 1,600 Lyrs and has a sun-like companion. The discovery was made by a team at the Harvard-Smithsonian Center for Astrophysics and the Gaia star-mapper, in combination with the International Gemini Observatory.
The black hole is 10X more massive than the Sun and three times closer to us than the previous record-holder.
Gaia BH1 was detected by the wobble it exerts on its stellar companion, but it doesn’t feed on its star. In fact, there are far more tranquil than feeding black holes and that makes them invisible.
How Gaia BH1 was formed in the Milky Way is uncertain. It lies in the constellation of Ophiuchus. Astrophysicists reckon that there are about 100 million black holes in our galaxy, many of them closer to us than the current discovery. The black hole discovery was announced in the Monthly Notes of the Royal Astronomical Society.
