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 Milky Way[ c ] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
The Bright Star Catalogue, which is a star catalogue listing all stars of apparent magnitude 6.5 or brighter, or roughly every star visible to the naked eye from Earth, contains 9,096 stars. [1] The most voluminous modern catalogues list on the order of a billion stars, out of an estimated total of 200 to 400 billion in the Milky Way .
Cygnus (constellation) Visible at latitudes between + 90 ° and − 40 °. Best visible at 21:00 (9 p.m.) during the month of September. Cygnus is a northern constellation on the plane of the Milky Way, deriving its name from the Latinized Greek word for swan. [1] Cygnus is one of the most recognizable constellations of the northern summer and ...
Astronomical naming conventions. In ancient times, only the Sun and Moon, a few stars, and the most easily visible planets had names. Over the last few hundred years, the number of identified astronomical objects has risen from hundreds to over a billion, and more are discovered every year. Astronomers need to be able to assign systematic ...
Delphinus is in a rich Milky Way star field. Alpha and Beta Delphini have 19th century names Sualocin and Rotanev, read backwards: Nicolaus Venator, the Latinized name of a Palermo Observatory director, Niccolò Cacciatore (d. 1841). [3] Alpha Delphini is a blue-white hued main sequence star of magnitude 3.8, [10] 241 light-years
In Egyptian mythology, the Milky Way was considered a pool of cow's milk. The Milky Way was deified as a fertility cow-goddess by the name of Bat (later on syncretized with the sky goddess Hathor). The astronomer Or Graur has suggested that the Egyptians may have seen the Milky Way as a celestial depiction of the sky goddess Nut. [11]
The Milky Way as seen from Earth, with prominent dark features labeled in white, as well as prominent star clouds labeled in black. The Great Rift, a series of dark patches in the Milky Way, is most visible in the southern sky. [65] Some cultures have discerned shapes in these patches.
