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 ...

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 ...

The quasar, as bright as 500 trillion suns, has evaded astronomers for over 40 years because of its incredible luminosity. Skip to main content. Scientific American. February 20, 2024.

CAPE CANAVERAL, Fla. (AP) — 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 ...

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.

The black hole powering the quasar, the astronomers find, is 1.4 billion times as massive as the sun, in line with previous estimates. What’s new is the detection of the host galaxy, whose stars ...
