Astronomers have discovered that rapidly spinning extreme dead stars or pulsars push it to the edge, blasting out radio ...

Most stars in our universe come in pairs. While our own sun is a loner, many stars like our sun orbit similar stars, while a host of other exotic pairings between stars and cosmic orbs pepper the ...

Scientists have uncovered a "universal law" that applies to certain extreme, ultra-dense stars, and the research could help to shed light on mysterious flashes known as fast radio bursts (FRBs) that ...

Astronomers have uncovered what appear to be 21 neutron stars in orbit around stars like our Sun. The discovery is surprising because it is not clear how a star that exploded winds up next to a star ...

Using NASA’s Swift satellite, McGill University and Penn State University astronomers have identified an object that is likely one of the closest neutron stars to Earth — and possibly the closest. The ...

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 ...

Some neutron stars probably have something strange lurking in their cores, according to a recent study. Neutron stars are already some of the most peculiar objects in the universe. They contain enough ...

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent ...

In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects form. These pairs are capable of producing powerful cosmic collisions. The ...

By Will Dunham WASHINGTON, April 3 (Reuters) - A supernova - the explosive death of a star - is always violent, blasting material into space while typically leaving behind a compact stellar remnant ...
