F200DB-045
F200DB-045
Possibly one of the oldest galaxies observed
F200DB-045 is a candidate high-redshift galaxy, with an estimated redshift of approximately z = 20.4,[1][2] corresponding to 168 million years after the Big Bang.[3] If confirmed, it would be one of the earliest and most distant known galaxies observed.
F200DB-045 would have a light-travel distance (lookback time) of 13.7 billion years, and, due to the expansion of the universe, a present proper distance of 36.1 billion light-years.[3]
Nonetheless, the redshift value of the galaxy presented by the procedure in one study[1] may differ from the values presented in other studies using different procedures.[2][4]
