Quasars acting as strong gravitational lenses are among the rarest finds in astronomy. Out of nearly 300,000 quasars cataloged in the Sloan Digital Sky Survey, only twelve candidates were identified, ...

Quasars are some of the brightest objects in the universe. A quasar is powered by large amounts of matter falling into the supermassive black hole at the center of a galaxy. Collisions and mergers ...

Astronomers from Seoul National University, South Korea and elsewhere report the detection of 62 new luminous quasars as part of the All-sky BRIght, Complete Quasar Survey (AllBRICQS). The discovery ...

This image, taken by NASA’s James Webb Space Telescope, shows an ancient quasar (circled in red) with fewer than expected neighboring galaxies (bright blobs), challenging physicists’ understanding of ...

Observations confirm astronomers' expectation that early-Universe quasars formed in regions of space densely populated with companion galaxies. DECam's exceptionally wide field of view and special ...

Astronomers have used the wide-field view of the Dark Energy Camera to confirm that supermassive-black-hole-powered quasars in the early universe were packed into dense neighborhoods. However, it ...

A team led by University of Arizona astronomers has discovered the most distant quasar ever found, and they believe it was fully formed 670 million years ago after the big bang. Credit: Illustration ...

Quasars were a mystery when first discovered in the early 1960s. They are extremely distant, starlike objects that emit enormous amounts of energy. Years later, astronomers understood that quasars are ...
