To give some idea of the luminosity of a quasar, scientists at the Mullard Space Science Laboratory at University College London describe how the nearest quasar, 3C 272, has a luminosity of 2.5 x ...

CAMBRIDGE, MASS. — For the first time, astronomers have detected starlight from distant galaxies that host extremely bright supermassive black holes called quasars. Data from the James Webb ...

Quasar 3C 273, which was the first of its kind discovered, is as luminous as 4 trillion suns or 100 times brighter than the entire Milky Way. "For Hubble, ...

Astronomers first discovered quasars, the brightest and most powerful objects in the universe, 60 years ago. Now, scientists think they have unlocked the mystery behind what ignites these ...

Astronomers report that this quasar is so far away from Earth that it took over 12 billion years for us to see it. On Earth, quasars resemble stars. An artist’s impression shows the record ...

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 ...

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).

A quasar is a blindingly bright galaxy core — brighter than all of the galaxy's starlight combined, according to NASA.Through telescopes, these sometimes look like a single star in the sky, but ...

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.

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 ...
