I never imagined I was going to see something like this: A video of a star bursting in space, illuminating the interstellar dust around it at the speed of light. This is not a computer simulation. It's an actual time-lapse video taken over four years by the Hubble—and scientists don't know its origin yet.

The Helix Nebula, lies 650 light-years away, in the constellation of Aquarius. It is a typical example of a class of objects called planetary nebula. Planetary nebulae are actually the remains of stars that once looked a lot like our sun. These stars spend most of their lives turning hydrogen into helium in massive runaway nuclear fusion reactions in their cores. In fact, this process of fusion provides all the light and heat that we get from our sun.
