The Perseids (summer)

The Perseids appear to fly at us from the constellation Perseus, but they really originate from the comet Swift-Tuttle. The comet Swift-Tuttle orbits the sun once every 133 years. Every August, the Earth moves through its cloud of debris, bringing a spectacular light show to our planet. The Perseids generally peak in mid-August. Pictured here are the Perseids as seen in 2010 over Lake Mary in Flagstaff, Arizona, with the Milky Way as a backdrop. The Perseids have been observed by people for the past 2,000 years, according to NASA.
