Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

New research suggests that galaxies with quasars at their active hearts are seven times more likely to harbor elusive ...

Quasars are supermassive black holes that shoot out giant ... This afterglow is the cosmic microwave background (CMB), leftover radiation from just after the cosmos-birthing explosion that permeates ...

A new census reveals that 35% of supermassive black holes are hidden behind dust, disrupting major galactic models.

Scientists have discovered a supermassive black hole that appears to be "waking up" after being inactive for decades. The black hole at the heart of SDSS1335+0728—a distant galaxy 300 million ...

The motion of planets, stars, and even supermassive black holes are also way too weak to be detected directly, but they all add up to the gravitational wave background.

But the supermassive black holes found in galaxies’ centers, which can be as heavy as billions of suns, are more mysterious and influential. They somehow steer the formation and evolution of the ...

Astronomers have discovered a supermassive black hole-powered quasar that may have helped "turn on the lights" in the early universe The intense brightening and dimming of this quasar was observed ...

A pair of giant black holes about 3,000 light-years apart in the galaxy NGC 6240, 400 million light-years away. The galaxy's butterfly shape was caused by the collision of two smaller galaxies.

With monster ultramassive black holes like Phoenix A and Ton 618 out there, you might well wonder if there is a limit to just how big a black hole can get.

Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of ...
