Tulip Nebula in Cygnus. This brightest glowing cloud of interstellar gas and dust is found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. Tulip Nebula “blossoms” about 8,000 light-years away. In the field of view there is also microquasar Cygnus X-1, one of the strongest X-ray sources in planet Earth's sky. Driven by powerful jets from a blackhole accretion disk, its fainter bluish curved shock front is only just visible though, directly above the cosmic Tulip's petals.
