"The Northern Cross is a prominent asterism seen in the summer months formed by the brightest stars in the constellation Cygnus: Deneb, Sadr, Albireo, Rukh, and Gienah."
The Tulip Nebula, Sh2-101, is a HII region emission nebula located in the constellation Cygnus. The emission from the Tulip Nebula is powered by ultraviolet radiation of the hot young star HD 227018. This gorgeous nebula is about 8,000 light years away from Earth.
The Tulip Nebula is located about 2 degrees southwest of the Crescent Nebula (NGC 6888). Both objects can be found along an imaginary line drawn from Sadr (Gamma Cygni), the central star of the Northern Cross, to Albireo (Beta Cygni). Together they form the lower part of the Northern Cross. The Tulip Nebula was first discovered in 1959 by astronomer Stewart Sharpless.
