Cygnus X-1 is a black hole about 15 times the mass of the Sun in orbit with a massive blue companion star.  Astronomers used several telescopes including Chandra to study Cygnus X-1.  The combined data have revealed the spin, mass, and distance of this black hole more precisely than ever before.  Stephen Hawking lost a bet - originally placed in 1974 -- that Cygnus X-1 did not contain a black hole.

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. It is also called Sharpless 101 (Sh2-101) or the Cygnus Star Cloud because the nebula located in the constellation Cygnus.

Cygnus x-1 est une étoile binaire (à neutrons OU un trou noir car elle émet des rayons X mais est toujours sujette à controverse). Malgré une distance évaluée entre 4500 et 6000 années lumières, elle est visible avec des jumelles par beau temps car elle ferait 20 à 30 fois la masse solaire.
