Cygnus X-1
Videos
Cygnus X-1 is a galactic X-ray source in the constellation Cygnus and was the first such source widely accepted to be a black hole. It was discovered in 1964 during a rocket flight and is one of the s

The companion star of the black hole Cygnus X-1 is the brighter of the two stars in the middle of the photo. A bowshock is created by the jet of energetic particles from the black hole as they collide with the interstellar medium. It can be seen as the arc near top of the photo.

A binary star or binary star system is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars are among the most important objects in astrophysics because
Cygnus X-1
…systems such as HDE 226868/Cygnus X-1 may lead to further insights into the mechanics of active galaxies. The black hole and blue supergiant star form a binary system in which they orbit around their center of mass every 5.599829 days. From the perspective of Earth, the compact object never goes behind the other star…
