The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, Swift Observatory and other telescopes. A kilonova is a "the afterglow ...

Neutron star collisions are known to be factories in which heavy elements are produced. The fusion that takes place inside stellar cores can only produce elements up to iron; the r-process, or ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how ...

The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed an unexpected difference between the powerful winds launching from a disk around a neutron star and those from material circling ...

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is predicted to account for most of the universe's mass. As it cannot be detected and studied using ...

Using the joint Japan Aerospace Exploration Agency (JAXA), European Space Agency (ESA), and NASA X-Ray Imaging and Spectroscopy Mission (XRISM), scientists uncovered a dense but surprisingly slow wind ...

When two neutron stars collide, they unleash some of the most powerful forces in the universe, creating ripples in spacetime, showers of radiation, and even the building blocks of gold and platinum.

The collision of two neutron stars creates a cosmic explosion so powerful it forges gold, unleashes gravitational waves, and floods the universe with deadly gamma rays.
