Comet Castle

Comet PanSTARRS (C/2011 L4) displays a broad dust tail, a common sight for northern hemisphere observers as the comet rises higher after sunset. This particular view captures the comet's curving dust tail streaming away from what appears to be a mountaintop castle. While the scene is striking, the comet's traditional name is derived from the Pan-STARRS astronomical survey that discovered it.
