Stars, Sprites, Clouds, Auroras

Explanation: What are those red streaks in the sky? While photographing unexpected auroras over a distant thunderstorm, something extraordinary happened: red sprites . This brief instance of rarely imaged high-altitude lightning flashed so bright that it was witnessed by several people independently. Pictured over Minnesota , USA in May 2013, these red sprites likely followed an extremely powerful low-altitude conventional lightning bolt. Captured in the featured frame are a house and electrical pole in the foreground, thick clouds in the lower atmosphere , a lightning storm on the horizon, distant red sprites and green aurora in the upper atmosphere, and distant stars from our local neighborhood of the Milky Way Galaxy . The spectacular image is thought to be only the second known case of sprites and auroras photographed together, and possibly the first in true color.
