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 ...

Quasars, the luminous beacons at the centers of distant galaxies, have puzzled astronomers for decades with their dramatic brightness variations. Recent observations suggest that these celestial ...

Observations from the James Webb Space Telescope reveal that extremely fast, galaxy-scale outflows from luminous objects called quasars were much more frequent, and on average more powerful, about one ...

NASA’s Hubble Space Telescope is “seeing double.” Peering back 10 billion years into the universe’s past, Hubble astronomers found a pair of quasars that are so close to each other they look like a ...

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 ...
