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.
In 2004, astronomers discovered a star composed entirely of diamond, measuring 4,000 km across and 10 billion trillion trillion carats. 50 light years from Earth, the diamond star is classified as a crystallized white dwarf, the hot core that remains after a star burns out. Scientists confirmed that the crystallized carbon interior of the star is, in fact, the galaxy’s largest diamond. Technically named BPM 37093, called "Lucy" after the Beatles song, Lucy in the Sky with Diamonds.
