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 particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. BPM 37093 — a diamond star Cygnus X-1 — X-ray source

z=3.395 This is a radio galaxy. At the time of discovery, quasar Q0051-279 at z=4.43, discovered in 1987, was the most remote object known. In 1989, quasar PC 1158+4635 was discovered at z=4.73, making it the most remote object known. This was the first galaxy discovered above redshift 3. It was also the first galaxy found above redshift 2.
The BCG was also the most distant galaxy of the time. [48] [50] [51] [52] Abell 1930 (Bootes Cluster) 1936–1951 0.13 39 000 The BCG of this cluster was also the most distant galaxy of the time. [51] [53] Gemini Cluster 1932 − 1936 0.075 23 000 The BCG of this cluster was the most distant galaxy at the time. [53] [54]
The age of the oldest known stars approaches the age of the universe, about 13.8 billion years. Some of these are among the first stars from reionization (the stellar dawn), ending the Dark Ages about 370,000 years after the Big Bang. [1] This list includes stars older than 12 billion years, or about 87% of the age of the universe.
Observations of the galaxy UDFy-38135539 suggest that it may have played a role in this reionization process. The European Southern Observatory discovered a bright pocket of early population stars in the very bright galaxy Cosmos Redshift 7 from the reionization period around 800 million years after the Big Bang, at z = 6.60. The rest of the ...
This list uses the mean cosmological parameters of the Lambda-CDM model based on results from the 2015 Planck collaboration, where H 0 = 67.74 km/s/Mpc, Ω Λ = 0.6911, and Ω m = 0.3089. [3] Due to different techniques, each figure listed on the galaxies has varying degrees of confidence in them.
