Another black hole

Astronomers have found the second black hole in the middle of the Milky Way. The first was discovered three years ago. This black hole is called Sagittarus A* and has a mass 2,600,000 times greater than the Sun.

The current one, for its part, is much smaller, only 1,300 times greater than the Sun of the other to 280 km/s. Astronomers suspected there could be a black hole when they detected the powerful x-rays it emits, as well as the seven stars orbiting around it.
