It also had the brightest UVOT afterglow ever recorded once corrected for extinction. [46] It had the largest amount of energy ever recorded in the TeV range, [47] and had the most energetic photons ever recorded for a GRB, peaking at 18 TeV. [25] [20] The burst was ten times brighter than any previous GRB detected by the Swift mission. [48]
The highest-redshift quasar known (as of August 2024) is UHZ1, with a redshift of approximately 10.1, [48] which corresponds to a comoving distance of approximately 31.7 billion light-years from Earth (these distances are much larger than the distance light could travel in the universe's 13.8-billion-year history because the universe is expanding).
It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from Earth, with an apparent visual magnitude of 12.9. [2] The derived distance to this object is 749 megaparsecs (2.4 billion light-years). The mass of its central supermassive black hole is approximately 900 million times the mass of the Sun.
2.6 AU when Mars is diametrically opposed to Earth Kepler correctly characterized Mars and Earth's orbits in the publication Astronomia nova. It had been conjectured that the fixed stars were much farther away than the planets. Sun: Star 3rd century BC — 1609 380 Earth radii (very inaccurate, true=16000 Earth radii)
Up until the discovery of JADES-GS-z13-0 in 2022 by the James Webb Space Telescope, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, [7] having a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).
The Baby Boom Galaxy is a starburst galaxy located about 12.477 billion light years away (co-moving distance is 25.08 billion light years). [1] [4] Discovered by NASA's Spitzer Science Center at the California Institute of Technology, the galaxy is the record holder for the brightest starburst galaxy in the very distant universe, with brightness being a measure of its extreme star-formation ...
ULAS J1342+0928 has a measured redshift of 7.54, which corresponds to a comoving distance of 29.36 billion light-years from Earth. [1] [4] When it was reported in 2017, it was the most distant quasar yet observed. The quasar emitted the light observed on Earth today less than 690 million years after the Big Bang, about 13.1 billion years ago ...
