The Tulip Nebula

In the cosmic expanse, this image unveils the Tulip Nebula, a celestial gem captured in the classic Hubble palette. Revered in the Sharpless catalog by Steward Sharpless in 1959, this emission nebula graces the Swan constellation from a distance of approximately 6000 light-years. Two slender dark clouds, reminiscent of a tulip's silhouette against the backdrop of a red HII region, bestow the nebula its poetic moniker. Hovering slightly above the tulip, a striking pair of stars illuminates the scene—one radiating a yellowish glow, slightly larger, and the other a whitish brilliance, subtly smaller. The yellow-hued star, HDE 226868, unveils the cosmic enigma of Cygnus X-1, the first confirmed black hole, discovered in 1972, sparking a renowned bet between Stephen Hawking and Kip Thorne. This intricate tapestry of the Tulip Nebula and Cygnus X-1, residing at a distance of 6197 light-years, narrates the intertwined tales of stellar birth and the cosmic abyss, casting a spellbinding allure upon the cosmos.
