The Helix Nebula


Stars like our Sun end their lives by casting off their outer layers, briefly forming a spectacular “planetary nebula” like the Helix Nebula.  This brief video fades between images taken at different wavelengths which show different aspects of the nebula. Optical: Hot gas ejected from a dying star glows. Near-Infrared: Near-infrared light reveals cooler material. Mid-far-Infrared: Warm dust is identified in mid-infrared light. Infrared-Ultraviolet: The ultraviolet light traces the hot gas being expelled from the dying star.
