Thirty-one newly discovered ancient quasars are giving scientists their clearest view yet of the universe’s earliest giant black holes. Quasars are among the brightest objects in t...
A new study finds that two early-universe objects thought to be faint quasars are actually extraordinarily luminous galaxies powered by bursts of star formation. James Webb Space T...
Extreme quasars near the dawn of time are giving astrophysicists clues to the formation of supermassive black holes.
Quasars, distant cores of galaxies powered by supermassive black holes, are among the most luminous objects in the universe. While not uncommon, their brightness can make it diffic...
There are a number of things in the Universe that could wipe out life as we know it, but — for now, and for Earth — a blast from our galaxy's supermassive black hole isn't one of t...
A quasar is a supermassive black hole in the act of feeding, and it’s so bright that it drowns out the galaxy it sits in. That is a nuisance if you want to weigh the galaxy and wei...
Wave of ancient quasars from dawn of universe discovered by astronomers
Euclid’s expanding quasar census is revealing how enormous black holes emerged during the Universe’s infancy. More than 13 billion years ago, two brilliant objects blazed from gala...
The sharp-eyed and far-seeing Euclid space telescope has picked up 31 early quasars that have evaded detection until now. The post Euclid Telescope Finds Quasars Within 700 Millio...
W. M. Keck Observatory atop Mauna Kea on the Big Island and European Space Agency Euclid mission double known population of these extremely luminous distant galactic cores powered...
Using observations from multiple powerful telescopes, a team of astronomers studied a red quasar nicknamed "the Hatchling" at redshift 3.7. They may have identified one of the clea...
Astronomers using the W.M. Keck Observatory on Mauna Kea have confirmed two-thirds (21 of 31) of the most ancient quasars from the European Space Agency’s Euclid mission, including...
The Euclid space telescope has spotted the oldest quasars—the brightest objects in the universe—ever discovered, deepening a cosmic mystery that has been puzzling scientists.
Dust patterns around quasars may help reveal supermassive black holes kicked from galactic centers. When galaxies collide, the chaos does not stop with stars and gas. At the center...
An international team of scientists has used machine learning to identify seven rare quasar candidates, according to a new study.
Astronomers found seven rare quasar gravitational lens candidates using AI, providing a powerful new tool for studying black hole and galaxy evolution.
Astronomers have spotted the blisteringly hot exhaust fumes of the earliest quasars, intensely bright cosmic titans powered by feeding supermassive black holes.
Little red dots have puzzled astronomers since their discovery in JWST data from the Universe’s deep past. Their ‘powering engines’ might resemble a newly discovered phenomenon dub...
For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray ra...
Astronomers have speculated about the mysterious "little red dots" seen through the James Webb Space Telescope's images of the early universe: They could be galaxies, black holes,...
Blazars are galaxies with a jet aimed almost directly at us, and they flicker across every part of the spectrum at once. Almost everything we think we know about them comes from sh...
Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) have detected an extraordinary burst of radio light from a rare cosmic event in which an intermedi...
Astronomers have uncovered a previously underexplored population of faint, rapidly fading remnant radio galaxies, offering new insights into what happens after supermassive black h...
A jet erupting from a distant supermassive black hole-powered blazar is being gravitationally lensed by an unseen clump of dark matter, and that could tell us about the source of c...
