[moonshinegnomie]

the tulip nebula SH2-101. the nebula is located about 6000 light years away. also in the image near the top center is an object known as cygnus x-1. it is the first black hole detected. it is part of a binary star system with a supergiant star which is the what we see. the black hole is actually located about 20% of the distance between the earth and the sun. the black hole is estimated to be only about 300 kilometers in diameter but has a mass 21x the mass of the sun. its actually further away than the nebula around 7300 light years from earth
