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 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 ...
The nebula was formed about 70,000 years ago by the star EZ Canis Majoris throwing off its outer hydrogen layers, revealing inner layers of heavier elements. [2] Fast stellar winds, blowing at 1,700 km/s (3.8 million mph) from this star, create the bubble-shaped nebula as they sweep up slower moving material from an earlier phase of the star's evolution.
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.
[5] [6] The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity about 100,000 times that of the Sun. [5] The star is one of the primary sources illuminating the nebula ...
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.
NGC 6946, sometimes referred to as the Fireworks Galaxy, is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus.
Messier 34 (also known as M34, NGC 1039, or the Spiral Cluster) is a large and relatively near open cluster in Perseus.It was probably discovered by Giovanni Batista Hodierna before 1654 [4] and included by Charles Messier in his catalog of comet-like objects in 1764.
