Physicists have discovered a new class of subatomic particle that will provide unexpected insights into the fundamental building blocks of matter. The new particle is the so-called pentaquark - five quarks in formation.

Quark StarObservations of two stars, one unusually small and the other unusually cold, have led astronomers to think they are seeing evidence of a new form of matter and a new kind of star, one possibly made of elementary particles known as quarks and denser than any cosmic object other than a black hole. (NYT link: yada yada) Here's a related link on neutron stars and quark matter. I rather like the phrase strange quark matter... Anybody else hear about this?
