In this composite image, visible-light observations by NASA's Hubble Space Telescope are combined with infrared data from the ground-based Large Binocular Telescope in Arizona to assemble a dramatic view of the well-known Ring Nebula.
Called a planetary nebula, the Ring Nebula is the glowing remains of a Sun-like star.
The Hubble observations were taken Sept. 19, 2011, by the Wide Field Camera 3. The Large Binocular Telescope data were taken June 6, 2010. In the image, the blue color represents helium; the green, oxygen; and the red, hydrogen.
