Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts.

EVANSTON, Ill. (CBS) -- Northwestern University astrophysicists were among those involved in an international research collaboration that has detected a gravitational-wave signal caused by a merger of ...

A team of scientists found a compact object 40,000 light-years from Earth that is either a very massive neutron star or an itsy-bitsy black hole, but they’re not sure which. The so-called mass gap ...

Scientists may have found the first evidence of primordial black holes, born in the very first seconds of the Big Bang. These tiny singularities can be smaller than a single atom but contain almost as ...

Shoujun Wang does research on high energy density laser-created plasma physics at Colorado State University’s Laboratory for Advanced Lasers and Extreme Photonics. A research team led by Colorado ...

This is the first image of Sagittarius A*, the supermassive black hole at the center of our galaxy, captured by the Event Horizon Telescope (EHT) and released in 2022. NASA via Getty Images In 1915, ...

A strange object about 40,000 light years away is either the heaviest neutron star or the lightest black hole we have ever seen, sitting in a mysterious void of objects that astronomers have never ...

New models of neutron stars show that their tallest mountains may be only fractions of millimetres high, due to the huge gravity on the ultra-dense objects. The research is presented today at the ...

Astronomers suspect that in the first second after the universe formed, the very first black holes also formed. These tiny though profoundly dense objects — think of an atom-sized particle wielding ...
