Astronomers observed ancient quasars that appear to be surprisingly alone in the early universe. The findings challenge physicists' understanding of how such luminous objects could have formed so ...

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 ...

We do see supermassive black holes in the process of merging, though, as we see galaxies with SMBH pairs, and even some candidates that seem to have sub-parsec pairs. EDIT: Modified so as not to ...

A new study uses spectroscopy to separate and study baby quasars. Quasars are supermassive black holes that have absorbed enormous brightness. Colors representing gases help researchers distinguish ...

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 ...

An artist's depiction shows how a quasar, which is the extremely bright core of a galaxy, unleashes torrents of energy from its central black hole. Credit: NASA / ESA / J. Olmsted (STScI) Scientists ...

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 ...

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 ...

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 ...
