Sauron's eye?

This is the Helix Nebula, in Aquarius, photographed by NASA's Spitzer Space Telescope (named for the late astrophysicist Lyman Spitzer, Jr. - see here - not for New York's new governor). The Helix is the visible evidence (though this image was made at x-ray frequency) of the death throes of a star similar to, but about three times larger than, our sun.

The image was downloaded from Discovery News.
