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 ...

It weighs more than 2 times the mass of our sun, but is only 18 miles wide. Astronomers have discovered the "most massive neutron star ever measured," amassing to more than two times the mass of our ...

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 ...

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

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 ...

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 ...
