Comet Lovejoy C/2014 Q2 passes about 50 million miles from Earth in this view of the night sky from North Bend, Washington. The comet's green coma results from molecules of diatomic carbon flourescing in ultraviolet sunlight. The tail is faint because this comet is producing very little dust. It's a long-period comet; it won't be seen again from Earth for about 8,000 years. Pleiades is the bright star cluster in the upper left corner of the image.
