This was possible thanks to an effect of gravity described by Einstein’s theory of general relativity. Pulsars are rapidly rotating neutron stars and are one of the most exotic objects in the Universe ...

Fast radio bursts originate near neutron stars, revealing their magnetically chaotic environments and scintillation patterns.

While the star was alive, nuclear fusion created a constant outward push that balanced the inward pull of gravity from the star's own mass. In the stellar remnants of a supernova, however ...

A black hole is one of the most fascinating and mysterious phenomena in the universe.

Stars are exploding, neutron stars collide, and supermassive black holes are merging. All of these things and many more create gravitational waves. As a result, the cosmos is filled with a ...

Neutron stars are the remnants of old stars that have run out of nuclear fuel and undergone a supernova explosion and a ...

These measurements from the world's gravitational wave observatories put constraints on the masses and spins of the merging objects such as black holes and neutron stars, and in turn this ...

To-date, all the gravitational waves that have been detected originated from black hole-black hole mergers, neutron star-neutron star mergers, or mergers of one of each. But collapsing supernovae ...

It uses extremely precise signals from pulsars—spinning neutron stars that emit regular radio pulses—to detect tiny ripples in space and time, called gravitational waves. This method is ...
