Pelican Nebula (IC5070) taken from Leeds UK by amateur astro-photographer urmymuse. The Pelican Nebula (also known as IC 5070 [1]) is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. [1]
The Abell catalogue is a catalogue of approximately 4,000 galaxy clusters with at least 30 members, almost complete to a redshift of z = 0.2. It was originally compiled by the American astronomer George O. Abell in 1958 using plates from POSS , and extended to the southern hemisphere by Abell, Corwin and Olowin in 1987.
The portion of the nebula resembling Mexico and Central America is known as the Cygnus Wall. This region exhibits the most concentrated star formation. [9] At optical wavelengths, the North America Nebula and the Pelican Nebula (IC 5070) appear distinct as they are separated by the silhouette of the dark band of interstellar dust L935. The dark ...
Rogelio Bernal Andreo (born 9 January 1969) is a Spanish-American astrophotographer.He is known for his photographs of deep sky objects.His work has been recognized by NASA as a regular contributor to their Astronomy Picture of the Day (APOD) [1] 80 times.
Its distance from Earth is about 25.2 million light-years or 7.72 megaparsecs, [2] similar to the distance of M101 (NGC 5457) in the constellation Ursa Major. [5] Both were once considered to be part of the Local Group , [ 6 ] but are now known to be among the dozen bright spiral galaxies near the Milky Way but beyond the confines of the Local ...
NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius.The nebula contains many proto-stars shielded by dark discs of gas, and young stars wrapped in expanding "cocoons" or expanding gases surrounding these small stars.
NGC 6914 is a reflection nebula located approximately 6,000 light-years away in the constellation of Cygnus, and was discovered by Édouard Stephan on August 29, 1881. [3] Ultraviolet radiation from stars in the Cygnus OB2 association ionize the nebula's hydrogen.
NGC 2440 is a planetary nebula, one of many in our galaxy. Its central star, HD 62166, [1] is possibly the hottest known white dwarf, about 400,000°F(200,000°C). The nebula is situated in the constellation Puppis. It was discovered by William Herschel on March 4, 1790. He described it as "a beautiful planetary nebula of a considerable degree ...
