The universe is a strange place. The X-ray Imaging and Spectroscopy Mission (XRISM) orbiting observatory recently highlighted ...

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by ...

When galaxies collide, it's not a gentle affair, but it does take millions of years. Over this time, the two massive star systems slowly merge together, their gravitational pull drawing them closer.

Pulsars could be helping scientists distinguish between gravitational waves caused by supermassive black hole collisions and ...

For decades, astronomers have listened to the cosmos through pulsars — rapidly spinning neutron stars that emit perfectly ...

The universe is big, weird, and filled with unexpected things. It’s the reason we send space probes to far reaches of our solar system and into deep space, it’s the reason we build telescopes, and ...

Massive stars know how to go out in style. Some of the brightest, longest-lived flares probably come from megastars getting shredded by supermassive black holes, researchers report in the June 6 ...

Humans are quite rightly fascinated by black holes, but could we ever harness them as an energy source? New research poses this question in order to explore some of the most wonderous cosmic events.

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by international pulsar timing array ...
