Image Description and Details :

Next to the tulip nebula is black hole Cygnus X-1. This is the first X-ray source discovered in Cygnus and the first black hole ever confirmed. The blue star HD 226868 revolves around this black hole in 5.5 days.
The black hole draws in gas from this star. The gas that piles up in the accretion disk around the black hole becomes so hot that it emits X-rays. In addition, the infalling gas also forms a jet.
This jet collides with the interstellar gas. The shock wave that this forms can be seen in this image.
