A death star's ghostly glow
The eerie glow of a dead star, which exploded long ago as a supernova, reveals itself in this Hubble Space Telescope image of the Crab Nebula. But, the ghoulish-looking object still has a pulse. Buried at its center is the star's tell-tale heart, which beats with rhythmic precision. The green hue has been added to give the image a Halloween theme.

It looks like a puff of steam but in one photograph you're seeing immense power and light years across. Photographs like this remind me how small and insignificant this earth is in the bigger picture.
