A recent Physical Review Letters study presents a new model for quark star merger ejecta that could resolve whether these cosmic collisions generate ordinary matter or something different. The ...

In the middle of the glowing gas cloud of a supernova remnant, about 8,000 light years away, sits the crushed heart of a dead star. Astronomers recently discovered that this neutron star left behind ...

Strange matter only occurs under very specific circumstances -- and astrophysicists are getting closer to understanding what those are.

Astronomers recently announced that they have found a novel explanation for a rare type of super-luminous stellar explosion that may have produced a new type of object known as a quark star.

For a large star, death is a bit of a squeeze. Once its nuclear fuel is spent, its core collapses, sparking a dramatic supernova explosion that blasts away the outer layers. The body left is a cold, ...

A quark is an elementary subatomic particle; three of them make up a proton or a neutron. Some scientists base the suggested existence of quark stars (which would be made of quarks instead of complete ...

The breakdown of matter into its tiniest quark components in a star’s core may have triggered the brightest supernova ever seen, a controversial new study says. If correct, this would be the first ...
