"To our knowledge, this galaxy-scale quasar-driven wind is currently the earliest one known." Using the James Webb Space Telescope (JWST), astronomers have spotted the earliest powerful "galaxy ...

At the center of 3C 273 lies asupermassive black hole feeding off nearby matter, creating the luminous phenomena we know as a quasar. For decades, 3C 273 has been a cornerstone of extragalactic ...

The black hole powering a quasar 13 billion light-years from Earth is half as massive as all the stars around it — a record high ratio for a quasar host galaxy, astronomers report in a paper ...

At the Microsoft Ignite 2024 conference on Tuesday, Microsoft and Atom Computing announced yet another breakthrough on the way to a fault-tolerant quantum computing: The two companies entangled 24 ...

(CNN) — Astronomers have for the first time spotted two galaxies in the throes of a deep-space “duel.” Using combined observations from ground-based telescopes over nearly four years, the ...

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, ...
