A pair of quasars that existed when the universe was only 3 billion years old has been spotted by the Hubble Space Telescope.

As a result, they detected 19 strongly-lensed, dual and projected quasars. The finding was reported in a paper published Jan. 15 on the arXiv pre-print server. Quasars, or quasi-stellar objects ...

Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could make sense of that.Ultra-self-interacting dark matter clumped into supposedly ...

Astronomers used an array of telescopes to find the most massive radio jet in the early universe. The celestial object is ...

Astronomers have discovered a massive, double-lobed radio jet stretching 200,000 light-years from a quasar that existed when ...

Using early data from the Dark Energy Spectroscopic Instrument (DESI), a team of scientists have compiled the largest sample ...

Black holes are more than just cosmic vacuum cleaners — they are powerful energy engines capable of redistributing vast amounts of power. Black holes spin and extract energy through powerful magnetic ...

"Microquasar jets have them all!" Standard quasars are powered by supermassive black holes feasting on surrounding matter and gas in central regions of some galaxies called active galactic nuclei ...
