    en.wikipedia.org/wiki/List_of_oldest_stars

    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.

  3. Age of the universe - Wikipedia

    en.wikipedia.org/wiki/Age_of_the_universe

    In physical cosmology, the age of the universe is the time elapsed since the Big Bang.Astronomers have derived two different measurements of the age of the universe: [1] a measurement based on direct observations of an early state of the universe, which indicate an age of 13.787 ± 0.020 billion years as interpreted with the Lambda-CDM concordance model as of 2021; [2] and a measurement based ...

    2013 — The galaxy Z8 GND 5296 is confirmed by spectroscopy to be one of the most distant galaxies found up to this time. Formed just 700 million years after the Big Bang, expansion of the universe has carried it to its current location, about 13 billion light years away from Earth (30 billion light years comoving distance). [19]

    In December 2012 the first candidate galaxies dating to before reionization were discovered, when UDFy-38135539, EGSY8p7 and GN-z11 galaxies were found to be around 380–550 million years after the Big Bang, 13.4 billion years ago and at a distance of around 32 billion light-years (9.8 billion parsecs).

  6. Cosmic age problem - Wikipedia

    en.wikipedia.org/wiki/Cosmic_age_problem

    For H 0 ~ 75 (km/s)/Mpc, the inverse of H 0 is 13.0 billion years; so after 1958 the Big Bang model age was comfortably older than the Earth. However, in the 1960s and onwards, new developments in the theory of stellar evolution enabled age estimates for large star clusters called globular clusters : these generally gave age estimates of around ...

  7. The Five Ages of the Universe - Wikipedia

    en.wikipedia.org/wiki/The_Five_Ages_of_the_Universe

    The Stelliferous Era, is defined as, "6 < n < 14". This is the current era, in which matter is arranged in the form of stars, galaxies, and galaxy clusters, and most energy is produced in stars. Stars will be the most dominant objects of the universe in this era. Massive stars use up their fuel very rapidly, in as little as a few million years.

  8. GN-z11 - Wikipedia

    en.wikipedia.org/wiki/GN-z11

    The object's name is derived from its location in the GOODS-North field of galaxies and its high cosmological redshift number (GN + z11). [12] It is observed as it existed 13.4 billion years ago, just 400 million years after the Big Bang ; [ 4 ] [ 13 ] [ 14 ] as a result, its distance is sometimes inappropriately [ 15 ] reported as 13.4 billion ...

    Like all galaxies, ALESS 073.1 is composed of gas, dark matter, and dust. It is made from stars that are held together by gravity. [5]ALESS 073.1 is estimated to have formed 12 billion years ago, just 1.2 billion years after the Big Bang. [4]
