Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant ...

Using observations from multiple powerful telescopes, a team of astronomers studied a red quasar nicknamed "the Hatchling" at redshift 3.7. They may have identified one of the clearest examples yet of ...

A team of astronomers led by the University of Arizona has observed a luminous quasar 13.03 billion light-years from Earth—the most distant quasar discovered to date. Dating back to 670 million years ...

Supermassive black holes appear to be present at the center of every galaxy, going back to some of the earliest galaxies in the Universe. And we have no idea how they got there. It shouldn’t be ...

Observations confirm astronomers' expectation that early-Universe quasars formed in regions of space densely populated with companion galaxies. DECam's exceptionally wide field of view and special ...
