Photo by @babaktafreshi | It was around midnight, and I was on the bottom of Zion Canyon, in Utah. The setting moon was still shining in this 45-minute exposure. The Earth's rotation created these star trails; the colors represent the stars' surface temperature, with blue being the hottest (young, massive stars) and orange-red the coolest (old red giants). Explore more of the night sky wonders with me @babaktafreshi. #twanight #zion #nationalparks #longexposure
