Coachella's electronic-focused Quasar stage came together in less than four months. Here's everything you need to know about the festival's newest and most ambitious project yet.

The map is based on a catalog of 1,295,502 quasar positions and redshifts, and is called "Quaia," a portmanteau of the words "quasar" and "Gaia," referring to the European Space Agency's Gaia ...

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 ...

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).
