The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed an unexpected difference between the powerful winds launching ...

On February 25, 2024, XRISM used its Resolve instrument to observe the neutron star GX13+1, which is the core of a once larger star that has burned out. GX13+1 is a bright X-ray source. These X-rays ...

The data from the NASA and ESA's XRISM has discovered unexpected disparities between two different types of cosmic winds.

XRISM found dense winds from a neutron star disc differ from those around black holes, challenging ideas on how such winds form and shape their environment.

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

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 ...

stellar collisions detected, including rare black hole–neutron star mergers, reshaping our view of star death and cosmic ...

A decade after the first discovery, scientists have used these waves to find a unique merger, a massive binary system and a ...

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

Gravitational-wave astronomy has exploded since 2015, capturing hundreds of black hole and neutron star collisions. With ever ...
