To give some idea of the luminosity of a quasar, scientists at the Mullard Space Science Laboratory at University College London describe how the nearest quasar, 3C 272, has a luminosity of 2.5 x ...

A quasar that close could have caused a lull in star formation that astronomers might someday detect by measuring precise ages for our galaxy’s oldest stars (SN: 3/23/22).

Astronomers have discovered the brightest object ever observed in the universe. Astronomers discovered a quasar, which is the "brightest of its kind" and the "most luminous object ever observed ...

Quasar 3C 273, which was the first of its kind discovered, is as luminous as 4 trillion suns or 100 times brighter than the entire Milky Way. "For Hubble, ...

For the study, the researchers compared NuSTAR observations of a distant quasar — designated J1429 +5447 — with unrelated observations of four months earlier by the Chandra X-ray telescope. The ...

In 2021, scientists detected the most distant quasar to date, known as P172+18. It took 13 billion years for the light from the quasar’s jets to reach us, and the jets are blasting out material ...

Picture a black hole so powerful that it swallows the equivalent of one sun every day.. Now imagine that black hole also has a mass that's 17 billion times larger than our sun. Scientists in ...

This particular quasar, called J1342+0928, is one of the most distant ever spotted at nearly 30 billion light years away. It formed less than 700 million years after the big bang.
