In a breakthrough discovery, scientists have found the most distant quasar yet known — and it's home to a seriously supermassive black hole.

Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most ...

Beyond its significance as the oldest-known X-ray quasar, UHZ1 offers compelling proof that the early universe is “seeded” with heavy black hole seeds with large birth masses that likely formed from ...

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).

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 ...
