The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792. [2]

Explanation: NGC 6888, also known as the Crescent Nebula, is a about 25 light-years across blown by winds from its central, bright, massive star. A triumvirate of astroimagers ( Joe, Glenn, Russell) created this sharp portrait of the cosmic bubble.

Sep 13, 2024 · Also cataloged as NGC 6888 and nicknamed the Crescent Nebula, Caldwell 27 was discovered by William Herschel in 1792. This stellar demolition zone lies within our own galaxy, about 4,700 light-years from Earth in the constellation Cygnus, the Swan.

The Crescent Nebula (NGC 6888) is a 25 light-year-wide emission nebula in the constellation Cygnus. This “cosmic bubble” in space owes its striking appearance to a central Wolf-Rayet star (WR 136) that pushes the hydrogen and oxygen atoms outward.

Dec 31, 2018 · It has the designation NGC 6888 in the New General Catalogue. The Crescent Nebula lies about 2.7 degrees southwest of Sadr, Gamma Cygni, the central star of the Northern Cross. It is a relatively faint object, about 26 light years across, that requires exceptionally dark skies and a UHC or OIII filter to be seen.

The Crescent Nebula, also known as NGC 6888, lies about 4,700 light-years away in the constellation of Cygnus. Star WR 136 will probably undergo a supernova explosion sometime in the next million years.
