The investigation could solve the mystery of how supermassive black holes grew so large in the early universe.

An exotic type of dark matter could explain some of the characteristics of our galaxy’s central supermassive black hole, but many cosmologists are leery of the idea ...

Observations of a distant quasar reveal that supermassive black holes may suppress star formation across intergalactic distances.

Researchers analyzed images of CDG-2 from NASA 's Hubble Space Telescope, the European Space Agency's Euclid space observatory, and the Japanese Subaru Telescope in Hawaii. At first glance, they saw ...

Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies ...

Many of us remember all too well our childhood bout of chickenpox: those itchy, scabby, red spots that appeared all over our ...

A burst of X-rays from 8 billion years ago may be the first clear evidence of a white dwarf torn apart by a black hole.

A stellar black hole is one that’s created from the gravitational collapse of particularly massive stars, typically greater than eight solar masses. For context, one solar mass is about equivalent to ...
