When the remnants of two stars collide, their union can launch a dazzling jet of high energy matter. A new computer simulation reveals how the merger, which forms a black hole, emits that bright beam, ...

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 ...

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

In a recent breakthrough, the XRISM mission has uncovered a puzzling cosmic phenomenon—a slow, dense wind emanating from the neutron star GX13+1. This unexpected discovery, detailed in a study ...

By Kat Troche September 2025 marks ten years since the first direct detection of gravitational waves as predicted by Albert ...

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

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 ...

Scientists have confirmed what became of a star that exploded in a stunning supernova visible to Earth more than three decades ago: It morphed into a neutron star, one of the oddest objects in the ...

Astronomers have discovered a mysterious unknown object in our galaxy that could be a breakthrough in the study of black holes. The “extremely dense remnant of a collapsed star” lies about 235,000 ...

There's a higher chance we're impacted by a solar flare or asteroid strike. Think of this as a thought experiment. When you purchase through links on our site, we may earn an affiliate commission.

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 ...
