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 ...

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 ...

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.

View Slideshow It's long been thought that a supernova, the most explosive event in the universe short of the big bang itself, typically leaves behind one of two remnants: a neutron star or a black ...

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 ...

ST. LOUIS ? Quark stars, exotic objects thathave yet to be directly observed, are part of a new theory to explain some ofthe brightest stellar explosions recorded in the universe.
