The Tulip Nebula

Location: Germany

Image Description and Details: A beautiful object for the classic Hubble palette.
Steward Sharpless added this object to his Sharpless catalog in the Swan in 1959. This emission nebula is about 6000 light years away from us. The two narrow dark clouds are reminiscent of a tulip in front of the red H2 region. Hence the name "Tulip Nebula". Slightly above the tulip on the right is a conspicuous pair of stars, one yellowish and lighter, the other whitish and slightly smaller. At the yellow bright star (HDE 226868) is the X-ray source Cygnus-X1, the first proven black hole, whose detection succeeded in 1972 and Stephen Hawking made a bet with Kip Thorne. The distance of Cygnus X-1 is given as 6197 light years.
Fortunately, I was still able to collect enough light despite the black hole to present this picture to you. ;-)

Clear Skies and stay well
