The Helix Nebula in Infrared

helix-nebula-in-ir

When viewed in IR by the Spitzer Space Telescope, the Helix Nebula shows a glow that suggests that the central star is surrounded by an unusual cloud of dust. One theory is that the cloud is made up of debris from collisions between the material ejected by the star when it exploded and the comets and other bodies in that star’s equivalent of the Solar System’s Kuiper Belt.
