A quasar is a powerful source of light, created by torrid gas orbiting a gargantuan black hole at the center of a galaxy. The intense radiation from one quasar, named VIK J2348-3054, has probably ...

Astronomers discovered a quasar, which is the "brightest of its kind" and the "most luminous object ever observed," using the European Southern Observatory's (ESO) Very Large Telescope (VLT), a ...

Astronomers have spotted the brightest known object in the universe, and it’s a quasar powered by the fastest-growing black hole on record, according to a new study. Initially classified as a ...

The James Webb Space Telescope has uncovered something extraordinary: a quasar within the Milky Way! This video unpacks the science behind quasars, the telescope’s incredible capabilities ...

Yuzuru Yoshii at the University of Tokyo and his colleagues found these hints while examining the light of a quasar, an extremely bright object at the centre of a galaxy powered by matter falling ...

Astronomers have found the oldest-known X-ray quasar in the universe — and its properties align exactly with predictions for a new class of distant objects made by Yale astronomer Priyamvada Natarajan ...

SRGA J2306+1556 is a radio-loud quasar at a redshift of approximately 0.44, discovered in 2022 with Spektr-RG. Previous observations of SRGA J2306+1556 have found that it is heavily obscured and ...

Utilizing DECam's massive field of view, the team conducted the largest on-sky area search ever around an early-Universe quasar in an effort to measure the density of its environment by counting ...

A Yale-led team of astronomers has 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, ...
