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

Supermassive black hum: Scientists discover gravitational wave background that permeates universe The source could be merging black holes — or something more 'mind-bending' ...

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.

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.

Supermassive black hole found only half a billion years after Big Bang There just isn't time for something that big to grow from a supernova remnant. John Timmer – Nov 6, 2023 5:45 pm | 132 ...

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 ...

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.

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 ...
