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

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

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

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

"Interestingly, the quasar powering this massive radio jet does not have an extreme black hole mass compared to other quasars." ...

Abstract: Quasars in the Age of Time-Domain Astronomy: Black hole feeding, visible as quasars, is a critical ingredient in many fields from galaxy evolution to multi-messenger gravitational wave ...

Astronomers have characterized the largest-ever early-Universe radio jet. Historically, such large radio jets have remained elusive in the distant Universe. With these observations, astronomers have ...

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 ...

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

Scientists peering into the early universe are baffled to see lonely quasars drifting away in the void. Quasars are one of ...

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 ...
