See it on NASA's siteStar trails are what you get when you leave a camera shutter open for a long time. The stars appear to move across the sky as the Earth rotates, drawing arcs of light. This photo captures the fun of a star party, where amateur astronomers gather to share views through their telescopes. These events are a great way to experience the night sky.
