A dark galaxy is a hypothesized galaxy with no (or very few) stars. They received their name because they have no visible stars but may be detectable if they contain significant amounts of gas. Astronomers have long theorized the existence of dark galaxies, but there are no confirmed examples to date. [1]
NGC 1052-DF2, an ultra diffuse galaxy. An ultra diffuse galaxy (UDG), or dark galaxy, [1] is an extremely low luminosity galaxy, the first example of which was discovered in the nearby Virgo Cluster by Allan Sandage and Bruno Binggeli in 1984. [a] These galaxies have been studied for many years prior to their renaming in 2015. Their lack of ...
As in all real images from our Arm of the galaxy much is obscured by the Great Rift, dark dust clouds that span from Cygnus to Centaurus. In astronomy , the Great Rift (sometimes called the Dark Rift or less commonly the Dark River ) is a dark band caused by interstellar clouds of cosmic dust that significantly obscure ( extinguish ) the center ...
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
The name describes the galaxy's appearance from the Earth: a hazy band of light visible in the night sky, formed from billions of stars that cannot be individually distinguished by the naked eye. The Milky Way Galaxy has a diameter of 100,000–200,000 light-years and is estimated to contain 100–400 billion stars and at least that number of ...
The quasar is near the center of the image; no obvious host galaxy is seen. Near the top of the image is a strongly disturbed and star-forming galaxy. Near the quasar is a blob of gas that is apparently being ionized by the quasar radiation. The pointlike object on the lower right is a foreground star seen by chance in the field of view.
Teens are getting high by inhaling canisters of nitrous oxide — specifically one called Galaxy Gas. The legitimate use of the gas, which is manufactured by a culinary supply company, is to ...
A 2015 paper discovered that there is a ring-like filament of stars called Triangulum–Andromeda Ring (TriAnd Ring) rippling above and below the relatively flat galactic plane, which alongside Monoceros Ring were both suggested to be primarily the result of disk oscillations and wrapping around the Milky Way, at a diameter of at least 50 kpc ...
