The Tulip Nebula, or Sharpless 101 (Sh2-101) or the Cygnus Star Cloud is an emission nebula located in the
constellation Cygnus. It is so named because it appears to resemble the outline of a tulip when imaged
photographically. It was catalogued by astronomer Stewart Sharpless in his 1959 catalog of nebulae.
It lies at a distance of about 6,000 light-years (5.7×1016 km; 3.5×1016 mi) from Earth. The Tulip nebula,
at least in the field seen from earth, is in close proximity to microquasar Cygnus X-1, site of one of
the first suspected black holes.[Text adapted from WIKIPEDIA]
