A photographer recently snapped images of vibrant green streaks of light hanging apparently motionless in the star-filled sky above a U.S. mountain range. The eerie light show may look like auroras, but it's actually an even rarer phenomenon.
Aaron Watson captured the stunning display near the West Elk Mountains in Colorado. The streaky emerald lights emerged just before midnight on June 21 and lasted for around 2 hours, during which they slowly shifted across the sky, Watson told Live Science in an email. Similar but less-intense versions of these lights were also spotted in other parts of Colorado, according to Spaceweather.com.
