This image, taken with the Atacama Large Millimeter/submillimeter Array (ALMA), shows the molecular gas content of two galaxies involved in a cosmic collision. The one on the right hosts a quasar –– a ...

Galaxies formed and grew billions of years ago by accumulating gas from their surroundings, or colliding and merging with other young galaxies. These early stages of galaxy assembly are believed to be ...

Astronomers have used a pair of Mauna Kea telescopes to shed light on one of the universe’s earliest stages of development. Using the Gemini North and Subaru telescopes, a team led by astronomer ...

Rare twin quasars discovered merging in the early universe, revealing a galaxy collision and shared gas fueling supermassive ...

A rare and powerful discovery has revealed two quasars merging in the early universe, offering a direct glimpse into how ...

UK astronomers using the 15-m James Clerk Maxwell Telescope in Hawaii have discovered enormous quantities of cosmic dust in the most distant quasar yet observed. The quasar, called SDSS J1148+5251 is ...

The celestial objects were unknown until a little more than 60 years ago, but even the name is now part of our lexicon.

Astronomers observed the elusive starlight surrounding some of the earliest quasars in the universe. The findings may shed light on how the earliest supermassive black holes became so massive despite ...

Astronomers, using the Atacama Large Millimeter/submillimeter Array (ALMA), have confirmed the existence of a close quasar ...
