Star cluster NGC 6520 and dark nebula Barnard 86 within the Large Sagittarius Star Cloud. Superimposed upon the Large Sagittarius Star Cloud is the bright open cluster NGC 6520. Close by to the west is the small dark nebula Barnard 86, a Bok globule described by Edward Emerson Barnard as “a drop of ink on the luminous sky”.
NGC 206 is located in a spiral arm of the Andromeda Galaxy, in a zone free of neutral hydrogen. It contains hundreds of stars of spectral types O and B . The star cloud has a double structure: one region has an age of around 10 million years and includes several H II regions in its border; the other region has an age of 40 to 50 million years ...
The Great Rift covers one third of the Milky Way, and is flanked by strips of numerous stars, such as the Cygnus Star Cloud. [2] West of the Cepheus Clouds, the Funnel cloud/Le Gentil 3 and the bordering North America Nebula, the Great Rift starts with the Northern Coalsack at the constellation of Cygnus, where it is known as the Cygnus Rift.

The Taurus molecular cloud (TMC-1) is an interstellar molecular cloud in the constellations Taurus and Auriga. This cloud hosts a stellar nursery containing hundreds of newly formed stars. [2] The Taurus molecular cloud is only 140 pc (430 ly) away from Earth, making it possibly the nearest large star formation region.
R136 (formerly known as RMC 136 from the Radcliffe Observatory Magellanic Clouds catalogue [4]) is the central concentration of stars in the NGC 2070 star cluster, which lies at the centre of the Tarantula Nebula in the Large Magellanic Cloud.
The giant molecular cloud Orion A is the most active star-forming region in the local neighbourhood of the Sun. In the last few million years about 3000 young stellar objects were formed in this region, including about 190 protostars and about 2600 pre-main sequence stars. [6] The Orion A cloud has a mass in the order of 10 5 M ☉. [7]
NGC 602c is a looser grouping 11 arc-minutes to the NE, which includes the WO star AB8. [9] 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 ...
