A zombie star feasting on its surrounding planets and asteroids hasn't escaped the cannibalistic process unscathed. Resulting debris has given this white dwarf a metal scar.
Using two of the agency's X-ray telescopes, NASA said researchers were able to observe a dead star's erratic behavior as it released a bright, brief burst of radio waves.
The mystery of what dwells within dead stars could be solved at last, thanks to supercomputer simulations that show neutron stars are comprised of "cold quark matter."
A runaway dead star predicted to have a close encounter with our solar system in tens of thousands of years will actually miss our neck of the cosmic woods.
