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

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

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

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

Galaxies in a quasar state can release powerful jets from their active supermassive black holes. The jets can extend far into intergalactic space, even for millions of light-years. The process for ...

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

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 ...

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 ...

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

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 ...
