Gizmodo:

In a few billion years, our dear Sun will look like this, a beautiful glowing eye of spent starstuff trash in the shape of Sauron’s Eye. And no ring is going to save us from this one.It’s the Helix Nebula, NGC 7293, 700 light-years away from Earth. Once upon a time it was a star like ours.

I’m going to be so bummed when that happens.
