Quasars represent some of the most luminous and energetic phenomena in the universe. These distant powerhouses are driven by supermassive black holes—colossal gravitational engines with masses ...

An international team of astronomers has discovered 25 new quasars by analyzing multiwavelength data from various surveys. All the newfound quasars were detected at redshifts greater than 4.6. The ...

JWST was used by the team to study quasars between 600 and 700 million years after the Big Bang. The phenomenal space telescope has provided detailed observations of the early universe, revealing ...

Black holes formed quasars less than a billion years after Big Bang A surprisingly normal looking quasar when the Universe was 750 million years old.

Many quasars are so luminous they can outshine the sun by as much as 27 trillion times. That means that if a quasar existed even at the edge of the solar system, its light output would boil away ...

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 ...

For the first time, scientists have peered back to the early days of the universe and found it moved five times slower than it does today.

Astronomers used the Hubble Space Telescope to find a pair of quasars residing in the cores of two galaxies. They existed when the universe was 3 billion years old.

Quasars, the most extreme phenomena in the universe, are triggered when galactic collisions deliver gas to feeding black holes, new research suggests. When you purchase through links on our site ...
