A neutron star and black hole were detected merging along an unusual oval orbit, challenging long-held theories about how ...

Chandra observations of RX J1856.5-3754 suggest that the matter in this collapsed star is even denser than nuclear matter, the most dense matter found on Earth. X-ray and optical data indicate that RX ...

Magnetars are some of the most extreme objects in the universe. A special class of neutron stars, they are celestial bodies that pack the mass of the Sun in a sphere the size of a city. On top of that ...

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown mini-galaxy leftover from an ancient cosmic crash. The "collision within a collision" ...

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

An international team of scientists have modelled formation and evolution of strongest magnetic fields in the Universe. An international team of scientists have modelled formation and evolution of ...

Astronomers have spotted a jaw-dropping collision between two neutron stars – and it may have produced gold and platinum. The discovery in a tiny, faraway galaxy is the first time this has been seen ...

This Collection features original research on the mechanisms driving star formation, the lifecycle of various stellar types, and the complex interactions between stars and their environments. The ...

An international team of scientists have modelled formation and evolution of strongest magnetic fields in the Universe. Led by scientists from Newcastle University, University of Leeds and France, the ...
