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

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

The densest cluster of supermassive black holes identified in the Universe. The background image was taken by Hyper Suprime-Cam on the Subaru Telescope. The red and blue shadows represent the density ...

Astronomers have confirmed a rare dual quasar system, J2037–4537, from just 1 billion years after the Big Bang, shedding ...

A Yale-led team of astronomers has 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, ...

Space might seem calm when gazing up at the night sky, but invisible waves ripple continuously through the universe, bending space and time. These waves, known as gravitational waves, carry crucial ...

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 ...

Research, led by Gabriela Canalizo of the University of California, Riverside, points to a spectacular collision of galaxies RIVERSIDE, Calif. – New images taken with NASA’s Hubble Space Telescope – ...

Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could make sense of that. Ultra-self-interacting dark matter clumped into ...

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 ...

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 ...
