Star formation has ceased within at least 16 million light-years of the quasar. A similar phenomenon may have fried the Milky Way when it was young.

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 ...

Astronomers know that if they spot an incredibly luminous quasar, it means a rapidly growing supermassive black hole also is present, and J0529-4351 is the most impressive yet on both counts ...

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 ...

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 ...

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 ...

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 ...

Artist's rendering of the accretion disk in ULAS J1120+0641, a very distant quasar powered by a supermassive black hole with a mass two billion times that of the Sun. Credit: ESO/M. Kornmesser ...

“In this work, we have discovered that this quasar is very likely to be a supermassive black hole with a jet pointed towards Earth — and we are seeing it in the first billion years of the universe,” ...
