Our readers agree that in the unlikely event you were able to approach a neutron star, it would look very smooth and bright ...

Astronomers have used an X-ray spacecraft called XRISM to observe powerful winds blowing from a neutron star — the findings ...

The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic events in the universe, producing a variety of signals that can be ...

XRISM found a slow, thick wind from a neutron star, pointing to temperature as the key driver of cosmic wind behavior. The ...

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 ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a visual frequency scale (at left) track the steady rise in the frequency of ...

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 ...

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 ...

The transformation of neutrinos in a neutron star merger could be crucial to shaping the way events of the collision unfold. For the first time, a team of physicists has simulated how neutrinos change ...

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.
