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

When two neutron stars collide, they unleash some of the most powerful forces in the universe, creating ripples in spacetime, ...

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 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 ...

Mon., June 23, 2025 A composite image of the supernova 1E0102.2-7219 contains X-rays from Chandra (blue and purple), visible light data from VLT’s MUSE instrument (bright red), and additional data ...

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 ...

Creating a neutron star Before you can get this ideal cosmic laboratory, a star first has to die. The end of a star’s life depends largely on its mass. Unremarkable stars like the Sun go out with a ...

In a bizarre gamma-ray space explosion whose light reached Earth in 2023, a team led by astronomer Run-Chao Chen of Nanjing ...

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 ...

When you think of telescopes in space, you probably think of the Hubble Space Telescope and its younger, larger sibling, the ...

Neutron stars escape collapse into a black hole thanks to degeneracy pressure produced by their neutrons, which is able to fight the crushing force of gravity. What exactly lies at the heart of a ...
