Sharpless 101<\/b>\u00a0(Sh2-101<\/b>) is a\u00a0H II region<\/a>[1]<\/a><\/sup>\u00a0emission nebula<\/a>\u00a0located in the constellation\u00a0Cygnus<\/a>. It is sometimes also called the\u00a0Tulip Nebula<\/i>\u00a0because it appears to resemble the outline of a\u00a0tulip<\/a>\u00a0when imaged photographically. It was catalogued by astronomer\u00a0Stewart Sharpless<\/a>\u00a0in his 1959 catalog of nebulae. It lies at a distance of about 6,000\u00a0light-years<\/a>\u00a0(5.7\u00d71016<\/sup>\u00a0km; 3.5\u00d71016<\/sup>\u00a0mi) from\u00a0Earth<\/a>.<\/p>\n

Sh2-101, at least in the field seen from Earth, is in close proximity to microquasar\u00a0Cygnus X-1<\/a>, site of one of the first suspected\u00a0black holes<\/a>. Cygnus X-1 is located just out of the field of view of the photo in the infobox. The companion star of Cygnus X-1 is a spectral class O9.7 Iab supergiant 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 the pair is separated by 0.2 astronomical units. 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.
