A supermassive black hole in the center of H1821+643, a quasar about 3.4 billion light-years away from Earth, is rotating at about half the speed of light.
This...
Gaia’s data release 3 (DR3) contains new and improved details for almost 2 billion stars in our Milky Way Galaxy as well as for a subset of solar system...
Using archival and new data from the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have imaged 3C 273, a radio-loud quasar located some...
Astronomers using the NASA/ESA Hubble Space Telescope have spotted GNz7q, a black hole that existed only 750 million years after the Big Bang, in one of...

Thanks to the presence of a gravitational lens, the NASA/ESA Hubble Space Telescope has captured five separate images of 2M1310-1714, a quasar located...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected a galactic-scale supermassive black hole-driven wind in HSC J124353.93+010038.5...
An international team of astronomers from the United States and the United Kingdom has made the discovery of a giant, almost symmetrical arc of galaxies...
Astronomers from the Gaia Gravitational Lenses group have identified 12 quadruply-imaged gravitationally-lensed quasars using machine-learning methods...
The two newly-discovered pairs of quasars, J0749+2255 and J0841+4825, existed 10 billion years ago and resided in the cores of merging galaxies, according...
The source of the 160,000-light-year-long jet of particles is PSO J352.4034-15.3373 (PJ352-15 for short), a rapidly growing supermassive black hole, or...
Astronomers using several ground-based telescopes have spotted the most distant cosmic jet discovered so far. Its source is PSO J172.3556+18.7734, a radio-loud...
The newly-discovered quasar is located approximately 13.03 billion light-years away from Earth. Designated J031343.84-180636.4 (J0313-1806 for short),...
Astronomers have observed a bright one-sided jet of material ejected at three-quarters the speed of light from the core of the blazar PSO J030947.49+271757.31...
