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).
3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo.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]
A burst as energetic and as close to Earth as 221009A is thought to be a once-in-10,000-year event. [10] [9] It was the brightest and most energetic gamma-ray burst ever recorded, with some dubbing it the BOAT, or Brightest Of All Time. [9] [11] [12] [13]
The brightest gamma ray burst ever detected recently reached Earth. It’s 70 times longer than any other burst we’ve spotted.
Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day. The black hole ...
GN-z11 is a high-redshift galaxy found in the constellation Ursa Major.It is among the farthest known galaxies from Earth ever discovered. [5] [6] The 2015 discovery was published in a 2016 paper headed by Pascal Oesch and Gabriel Brammer (Cosmic Dawn Center).
Even so, scientists with the Planetary Society say the nova explosion will likely be the brightest one witnessed on Earth since 1975. How to see the T Coronae Borealis nova explosion in 2024
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 ...
