Physicists have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter that ...

A team of physicists from the universities of Amsterdam, Princeton and Oxford have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions ...

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 ...

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 ...

Astronomers have caught a white dwarf in a rare stage of its evolution as it orbits a "cosmic lighthouse" in the form of a ...

Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force — one of the four fundamental forces in nature, along with gravity, electromagnetism, and the ...

Rarest Stars in the Universe: Stars come in many forms, but some types are so rare that only a handful exist in our galaxy. For example, O-type stars account for just 0.00003% of the stars near the ...

When the roiling nuclear fusion inside of a star begins to die — gravity crushing into the star’s waning fuel-store of hydrogen atoms, fusing them into heavier helium nuclei — the universe usually ...

Volume rendering of density in a simulation of a binary neutron star merger. New research shows that neutrinos created in the hot interface between the merging stars can be briefly trapped and remain ...
