Violent death of an old sun-like star!

An infrared image of the Helix nebula, a cosmic starlet known for its vivid colors and eerie resemblance to a giant eye. The nebula, located about 700 light-years away in the constellation Aquarius, belongs to a class of objects called planetary nebulae—the carcasses of deceased sun-like stars.
When sun-like stars die, they blow out their outer gaseous layers. The layers are heated by the hot core of the dead star, called a white dwarf, and shine with infrared and visible colors. (Source: Spitzer Space Telescope )
