This object, called the Helix nebula, lies 650 light-years away in the constellation of Aquarius. Also known by the catalog number NGC it is a typical example of a class of objects called planetary nebulae. Discovered in the century, these cosm
A sun-like star in the late white-dwarf stage of its life blows out a huge gas bubble that glows with colors stemming from the ultraviolet light of the star. Ionized hydrogen glows red, and towards the center, doubly ionized oxygen appears green.
This infrared image from NASA's Spitzer Space Telescope shows the Helix nebula, a cosmic starlet often photographed by amateur astronomers for its vivid colors and eerie resemblance to a giant eye. 36 / 40 Photo by Comets Kick up Dust in Helix Nebula;
A dying star throws a cosmic tantrum in this combined image from Nasa's Spitzer Space Telescope and the Galaxy Evolution Explorer. The star's dusty outer layers are unraveling into space, glowing from the intense ultraviolet radiation being pumped out by
The Eye of God~~Dust and the Helix Nebula ~ Dust makes this cosmic eye look red. The eerie Spitzer Space Telescope image shows infrared radiation from the well-studied Helix Nebula (NGC a mere 700 light-years away in the constellation Aquarius
