The pair of galaxies were found lensed by galaxy cluster CL1358+62 (z = 0.33). This was the first time since 1964 that something other than a quasar held the record for being the most distant object in the universe. [132][135][136][133][130][137] PC 1247–3406. Quasar.
A quasar (/ ˈkweɪzɑːr / KWAY-zar) is an extremely luminous active galactic nucleus (AGN). It is sometimes known as a quasi-stellar object, abbreviated QSO. The emission from an AGN is induced by a supermassive black hole with a mass ranging from millions to tens of billions of solar masses, surrounded by a gaseous accretion disc.
This cluster contains many of the most luminous known stars, including R136a1. Credit: ESO/VLT. This is a list of stars arranged by their absolute magnitude – their intrinsic stellar luminosity. This cannot be observed directly, so instead must be calculated from the apparent magnitude (the brightness as seen from Earth), the distance to each ...
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 886 million times the mass of the Sun.
Messier object. The Messier objects are a set of 110 astronomical objects catalogued by the French astronomer Charles Messier in his Catalogue des Nébuleuses et des Amas d'Étoiles (Catalogue of Nebulae and Star Clusters). Because Messier was interested only in finding comets, he created a list of those non-comet objects that frustrated his ...
It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224. Andromeda has a D 25 isophotal diameter of about 46.56 kiloparsecs (152,000 light-years) [8] and is approximately 765 kpc (2.5 million light-years) from Earth. The galaxy's name stems from the area of Earth's sky in which it appears, the constellation ...
Due to the brilliance of the central quasar, the surrounding galaxy is outshone by it and hence is not visible from Earth. With an absolute magnitude of −30.7, it shines with a luminosity of 4 × 10 40 watts, or as brilliantly as 140 trillion times that of the Sun, making it one of the brightest objects in the known Universe.

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 ...
