Delve into the enigmatic realm of neutron stars—stellar remnants that defy our conventional understanding. Once blazing stars ...

Astronomers have doubled the number of black hole and neutron star mergers detected via gravitational waves in a "stellar ...

Gravity from mountains on rapidly rotating neutron stars produces ripples in space-time known as gravitational waves. The Laser Interferometer Gravitational Wave Observatory (LIGO) searches for such ...

The first-ever detection of gravitational waves was made 10 years ago today (Sept. 14). In celebration, Space.com takes you ...

New X-ray data from NASA’s Chandra telescope reveals Cassiopeia A’s chaotic final hours, showing how dying stars collapse and explode.

Scientists have captured the clearest signal yet of a black hole collision, confirming Stephen Hawking's theory.

Researchers have discovered that PSR B1937+21's incredible rotation speed is due to its process of accreting material from a ...

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, ...

PSR B1937+21 is a millisecond pulsar located in the direction of the constellation Vulpecula, renowned for its astonishing rotation speed of 642 revolutions per second. Since its discovery in 1982, it ...

The burst seems to have been caused by a highly extraordinary event, but scientists don’t yet know exactly what that could be ...

Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can ...
