Description

In a constellation rich in nebulae such as the Swan, there is an object commonly called the Tulip nebula. An incandescent cloud of interstellar gas and dust cataloged in 1959 by the astronomer Stewart Sharpless as Sh2-101.

About 8,000 light years away from Earth, the ultraviolet radiation from the young stars on the edge of the Cygnus OB3 association ionizes and feeds the emissions of the Tulip Nebula.

Near the center of the nebula there is a very bright star called HDE 227018, while in the upper right you can see an arch originating from Cygnus X-1, a microquasar, and from the star with which it shares a binary system. This is one of the most intense X-ray sources measurable from Earth, probably attributable to the presence of a black hole. Cygnus X-1 was in fact at the center of a bet between physicists Stephen Hawking and Kip Thorne, on the presence or absence of a black hole and ended in the 90s when the data reinforced the hypothesis of its existence.
