Dying star captured by NASA's Spitzer Space Telescope
Show's dying stars outer layers unraveling into space
WHAT IS IT?
The image shows the death of a star in the Helix nebula 650 light years from earth.
It is made from images from three telescopes.
GALEX has picked out the ultraviolet light pouring out of this system, shown throughout the nebula in blue, while Spitzer has snagged the detailed infrared signature of the dust and gas in yellow.
A portion of the extended field beyond the nebula, which was not observed by Spitzer, is from NASA's all-sky Wide-field Infrared Survey Explorer (WISE).
The brighter purple circle in the very center is the combined ultraviolet and infrared glow of a dusty disk circling the white dwarf.
