Microquasar GRS 1915+105

Microquasars are made of a black hole and an ordinary star. The black hole exhausts the other star and thereby emits X-rays. In this system some gas masses escape with 92% speed of light into space. What we see here on Earth is the impression of superluminal velocity.
The black hole rotates 950 times per second, 98% of the maximal speed for such objects. Its event horizon is 25 km away from the center.
