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 ...
While early stars have not been observed, galaxies have been observed from 329 million years since the Big Bang, with JADES-GS-z13-0 which the James Webb Space Telescope observed with a redshift of z=13.2, from 13.4 billion years ago. [10] [11] The JWST was designed to observe as far as z≈20 (180 million years cosmic time). [citation needed]
The timeline of the early universe outlines the formation and subsequent evolution of the Universe from the Big Bang (13.799 ± 0.021 billion years ago) [1] to the present day. An epoch is a moment in time from which nature or situations change to such a degree that it marks the beginning of a new era or age .
Four galaxies that existed more than 13 billion years ago have been identified and confirmed by scientists as the earliest known to date. These galaxies were present around 350 million years after ...
Named after Hindu deities, the star streams appear to be the remnants of two galaxies that merged with an early version of the Milky Way between 12 billion and 13 billion years ago when the first ...

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 light-years, its light-travel distance measurement.
“This is the oldest documented light in the history of the universe from 13 billion — let me say that again, 13 billion — years ago,” Biden said, introducing the highest-resolution images
