The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region in the north-west of Sagittarius in a star-forming region in the Milky Way's Scutum–Centaurus Arm. [3] It was discovered by Charles Messier on June 5, 1764. [ 4 ]

NGC 2032 (also known as ESO 56-EN160 and the Seagull Nebula) is an emission nebula in the Dorado constellation and near the supershell LMC-4 [2] and it consists of NGC 2029, NGC 2035 and NGC 2040. It was first discovered by James Dunlop on 27 September 1826, and John Herschel rerecorded it on 2 November 1834. [ 3 ]
Enormous Lyα nebula (ELAN) Around the quasar UM287 at around z=2.3. Cosmic filament illuminated by the quasar. MAMMOTH-1: 1,441,000 ly (442,000 pc) [6] Enormous Lyα nebula (ELAN) The nebula is associated with the galaxy overdensity BOSS1441, [6] which is a protocluster at z=2.3. The nebula represents the circumgalactic medium. Its emission is ...
This is a list of observed supernova remnants (SNRs) in the Milky Way, as well as galaxies nearby enough to resolve individual nebulae, such as the Large and Small Magellanic Clouds and the Andromeda Galaxy.
The Trapezium Cluster is a component of the much larger Orion Nebula cluster, an association of about 2,800 stars within a diameter of 20 light years. [10] The Orion Nebula is in turn surrounded by the much larger Orion molecular cloud complex which is hundreds of light years across, spanning the whole Orion Constellation.
RCW 49, also known as NGC 3247, is a H II region [1] nebula located 13,700 light years away. [2] Other designations for the RCW 49 region include NGC 3247 and G29 [3] and it is commonly known as the Whirling Dervish Nebula. [4] It is a dusty stellar nursery that contains more than 2,200 stars [2] and is about 300-400 light years across. [5]
The nebula, designated GJJC1, is likely about only 6,000 years old. [3] Two black holes of between 10 and 20 solar masses (M ☉) each were unearthed with the Very Large Array radio telescope in New Mexico and corroborated by the Chandra X-ray telescope in 2012. [18]
