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.
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.
Abell 2744 galaxy cluster – Hubble Frontier Fields view (7 January 2014). [1] Abell 383, the giant cluster of elliptical galaxies in the centre of this image, contains so great a mass of dark matter that its gravity bends the light from a background object into an arc, a phenomenon known as strong gravitational lensing.

The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142). [2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun , in the Perseus Arm of the Milky Way .
NGC 602 includes many young O and B stars and young stellar objects, with few evolved stars. [10] Ionisation in the nebula is dominated by Sk 183, an extremely hot O3 main sequence star visible as the bright isolated star at the centre of the Hubble image. [11] A population of candidate brown dwarfs was found in NGC 602 in 2024. This was the ...
