Dead Star’s Ghoulish Glow

In NASA’s recent Hubble Space Telescope picture of the Crab Nebula, a dead star’s ghoulish green glow can be seen—some 6,500 light-years from Earth. Despite the neutron star being dead, astronomers say the color is due to “the star’s tell-tale heart, which beats with rhythmic precision” at its center. Part of the constellation Taurus, this star seems to have dressed up for Halloween.
