This is the first direct look, in visible light, at a lone neutron
star, as seen by the NASA/ESA Hubble Space Telescope. The Hubble results show the
star is very hot (1.2 million degrees Fahrenheit at the surface), and
can be no larger than 16.8 miles (28 kilometers) across. These results
prove that the object must be a neutron star, because no other known
type of object can be this hot, small, and dim (below 25th magnitude).
