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

They found a type of ultra-powerful galaxy that gobbles up everything around it. Its energy is so intense that, if it were ...

Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could ...

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 ...

"We would like to understand the difference between these systems, which holds the clue to understand just how many cosmic ...

Astronomers have discovered an enormous radio jet stretching over 200,000 light-years from a quasar in the early universe, ...

19 quasars identified, including lensed, dual, and projected types Observations conducted with P200/DBSP at Palomar Observatory Findings advance studies of supermassive black holes and redshifts ...

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 ...

"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 ...

These jets become elusive the farther back in time astronomers try to look because of the so-called cosmic microwave background. The ancient radiation, the earliest fossil of light from 380,000 years ...
