Information about Sh2-101
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.
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.
Cygnus X-1 is the brighter of the two stars (lower star) in close
vertical proximity just to the right of the Tulip nebula.
