PIX4620553: Nebula NGC 7023 in Cephee - Iris Nebula in Cepheus - The nebula of the Iris (NGC 7023) is a reflexion nebula illuminated by the star HD 200775. Infrared observations indicate that this nebula contains PAH (aromatic polycyclic hydrocarbons), molecules composed of carbon atoms and hydrogen. NGC 7023 (The Iris Nebula) is located 1400 Light Years away. The bright star HD 200775 shining through the nebula NGC 7023 is a 10 solar mass star centrally imbedded in a region surrounded by ambient molecular cloud material. Infrared observations indicate that this nebula may contain complex carbon molecules known as PaHS / Bridgeman Images
PIX4620819: Field around the Nebula Henize 55 - The Henize 55 star forming region in the LMC - Henize 55 (NGC 2014), on the right, is a star-forming region located north of the Great Magellan Cloud. Image obtained from the 1.2m Schmidt UK telescope of Siding Spring. The nearby Large Magellanic Cloud (LMC) is a very active star - forming galaxy. The most massive region of star formation is around 30 Doradus (the Tarantula nebula) which can be seen with the unaided eye, but hundreds of lesser examples are visible with a telescope. This picture shows one of the more intriguing, NGC 2014 (Henize 55), at right. It contains cluster of hot, young stars, almost hidden in the brightest part of the nebula. The energetic ultraviolet light from these stars is absorbed by hydrogen and produces the distinctive red glow from an enormous distance around the cluster. This picture was made photographically from three glass plates taken with the UK Schmidt telescope of Siding Spring / Bridgeman Images
PIX4621177: Taurus Molecular Cloud - Taurus Molecular Cloud - This region is located on the border of the Taurus and Persee constellations. Covering about 20 x 30 degres, this image shows a complex of emitted nebulae, star clusters, reflexion nebulae and dark nebulae. A molecular cloud is a region of dense gas and dust composed mainly of molecular hydrogen and helium. It's a birthplace of stars. The Molecular Cloud of Taurus is located about 400 years ago - light, and is one of the closest molecular clouds to our solar system. The California Nebula (NGC 1499), an emission nebula located about 1000 years ago - is visible at the top right. The dark nebulae B7, B18 and B19 are visible near the center of the image. Les Pleiades, M45, is the open cluster at the bottom right center. The open clusters NGC 1817, NGC 1746, NGC 1647 are on the left side of the image. The Hyades, Melotte 25, is a V-shaped cluster at the bottom left. It is the closest open cluster, located at a distance of about 151 light years. Aldebaran, Alpha Tauri, a bright red star with a magnitude of 0.75 to 0.95, is located at one end of the V, but does not belong to the cluster. The Taurus Molecular Cloud (TMC) is located on the border of the constellations of Taurus and Perseus. It is a large dense area of gas and dust in space made mostly of molecular hydrogen and helium. It is a birth place of stars, which form from the material in the cloud. Covering about 20 x 30 degrees, this wide - angle image shows a complex of bright red emission nebulae, star clusters, blue reflection nebulosity, and complex dark nebulae. The TMC is located about 400 light years away, and is one of the closest molecular clouds to our solar system. The California Nebula (NGC 1499), a very large red emission nebula, is at upper right. Emission nebulae are made up of glowing hydrogen gas. Located in / Bridgeman Images
