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 ...

Plenty of groups have been theorizing about primordial black holes (PBHs) recently. That is in part because of their candidacy as a potential source of dark matter. But, if they existed, they also had ...

This image, taken by NASA’s James Webb Space Telescope, shows an ancient quasar (circled in red) with fewer than expected neighboring galaxies (bright blobs), challenging physicists’ understanding of ...

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 ...

In the article published today in the Astronomy & Astrophysics journal, new evidence suggests how supermassive black holes, with masses of several billion times that of our Sun, formed so rapidly in ...

Scientists have found evidence that black holes that existed less than 1 billion years after the Big Bang may have defied the laws of physics to grow to monstrous sizes. The discovery could solve one ...

formed when the universe was merely 6 percent of its current age, or about 700 million years after the big bang. How black holes of several billion solar masses formed so rapidly in the very early ...

A monster jet of radio waves was discovered by astronomers. It’s double the width of our Milky Way galaxy and the jet is shooting out of a quasar. The quasar formed when the universe was about 1.2 ...

Sort of? You could conceivably red shift something so far that we no longer have the instruments to detect it, but I don't know how. The cosmic microwave background is still detectable, and it is at ...
