Comet Neowise appears over Mount Washington in the night sky as seen from Dee Wright Observatory on McKenzie Pass east of Springfield, Ore., last week. According to NASA, the lower tail, which appears broad and fuzzy, is the dust tail created when dust lifts off the surface of the comet's nucleus and trails behind the comet in its orbit. The upper tail is the ion tail, which is made up of gases that have been ionized by losing electrons in the sun's intense light.
