MUNICH, Germany, Nov. 20 (UPI) -- A comet approaching the sun has sprouted "wings," a U-shaped trail of gases that may be coming from a fragment breaking off the comet, German astronomers say.
Scientists from the Max Planck Institute for Solar System Research and the Wendelstein Observatory of the Ludwig-Maximilians-University reported Wednesday the discovery of the new features in images of Comet ISON taken at the end of last week.
