The name of this galaxy is based on a Redshift (z) measurement of nearly 7 (actually, z = 6.604). [ 5 ] Galaxy Cosmos Redshift 7 is reported to be the brightest of distant galaxies (z > 6) and to contain some of the earliest first stars ( first generation ; Population III ) that produced the chemical elements needed for the later formation of ...
Novae are initially designated via a "Nova [genitive form of constellation name] [year of discovery]" format, e.g. "Nova Cygni 1974" and "Nova Scorpii 2010". An official permanent name is usually soon assigned by the General Catalog of Variable Stars using the GCVS format for the naming of variable stars. When more than one nova is discovered ...

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 following is a list of all novae that are known to have occurred in 2018. A nova is an energetic astronomical event caused by a white dwarf accreting matter from a star it is orbiting (typically a red giant, whose outer layers are more weakly attached than smaller, denser stars) Alternatively, novae can rarely be caused by a pair of stars merging with each other, however such events are ...
Artist's conception of a white dwarf, right, accreting hydrogen from the Roche lobe of its larger companion star A nova (pl. novae or novas) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star (hence the name "nova", Latin for "new") that slowly fades over weeks or months.
Blue Nugget (also called BN) galaxies are a type of distant galaxy that only existed in the early universe. Blue nugget galaxies are small but high mass galaxies undergoing mass bursts of star formation, making many large, bright blue stars. As their stellar population evolves and ages, blue nugget galaxies transition into red nugget galaxies. [1]
