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

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

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 ...

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 ...

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

When scientists pointed XRISM’s sharp eyes at a distant neutron star, they expected answers. Instead, they uncovered a puzzle that could reshape how we understand cosmic winds and their role in ...

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 ...

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 ...

In a recent breakthrough, the XRISM mission has uncovered a puzzling cosmic phenomenon—a slow, dense wind emanating from the ...
