Two NASA telescopes discovered the oldest known black hole, ... 13.8 billion years ago. ... is actually much farther away and located beyond the cluster at 13.2 billion light-years from Earth. ...
QSO J0313−1806 [2] was the most distant, and hence also the oldest known quasar at z = 7.64, at the time of its discovery. [1] In January 2021, it was identified as the most redshifted (highest z) known quasar, with the oldest known supermassive black hole (SMBH) at (1.6 ± 0.4) × 10 9 solar masses.
The redshift of J0529-4351 is 3.962. The object itself is classified as a radio-quiet quasar.Fitting accretion models to the spectra yields an accretion rate of matter onto the black hole of 280 to 490 solar masses per year for an accretion disk around the black hole observed at an angle of zero to 60 degrees, with accretion occurring near the Eddington limit.
The quasar emitted the light observed on Earth today less than 690 million years after the Big Bang, about 13.1 billion years ago. [5] [9] The quasar's luminosity is estimated at 4 × 10 13 solar luminosities. [1] This energy output is generated by a supermassive black hole estimated at 7.8 × 10 8 solar masses. [1]
Given the universe is 13.7 billion years old, that puts the age of this black hole at 13.2 billion years. ... a mere 3.2 billion light-years from Earth, to magnify UHZ1 and its black hole much ...
[26] [27] [28] That burst had a redshift of 6.7, placing it approximately 190 million light-years closer to Earth than GRB 090423. Derek Fox, who led the observations done by Pennsylvania State University , suggests that the GRB was most likely the result of the explosion of a massive star and its demise, which would probably have signalled the ...
UHZ1 is a background galaxy containing a quasar.At a redshift of approximately 10.1, UHZ1 is at a distance of 13.2 billion light-years, seen when our universe was about 3 percent of its current age.
1963 — Maarten Schmidt discovers and analyzes the first quasar, 3C 273, as a highly red-shifted active galactic nucleus, a billion light years away; 1964 — Roger Penrose proves that an imploding star will necessarily produce a singularity once it has formed an event horizon
