Sh2-101 also known as the Tulip Nebula, at least in the field seen from Earth, is in close proximity to microquasar [Cygnus X-1], the site of one of the first suspected black holes. Cygnus X-1 is located about =nowrap15[′ west of Sh2-101. The companion star of Cygnus X-1 is a spectral class O9.7 Iab super-giant with a mass of 21 solar masses and 20 times the radius of the Sun. The period of the binary system is 5.8 days and 0.2 astronomical units separate the pair. The black hole has a mass of 15 solar masses and a Schwarzschild radius of 45 km. A bowshock is created by a jet of energetic particles from the black hole as they interact with the interstellar medium. It can be seen as an arc at the top of the photo on the left.
