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 ...

The universe’s brightest object is a quasar in a distant galaxy that’s powered by the fastest-growing black hole ever recorded, according to a new study. CNN values your feedback 1.

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).

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 ...

Astronomers witnessed two galaxies engaged in an intense deep-space battle for the first time. Watch the “cosmic joust” in action.

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.

Luckily, quasar VIK 2348-3054 has a known distance, determined by previous observations with the Atacama Large Millimeter/submillimeter Array (ALMA), and DECam's three-square-degree field of view ...

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 ...
