Astronomers may have discovered two of the strangest objects in the universe. Observations by the orbiting Chandra X-ray Observatory imply that stars named RXJ1856 and 3C58 are too small to be familiar neutron stars but might instead be a more exotic breed composed of degenerate quark matter. If so, the two would be the first credible examples of so-called strange stars, presenting theorists with a chance to pin down some of the properties of exotic matter.
