Shining Silver-Blue Clouds Captured in Night Sky Photo

Night sky photographer Ruslan Merzlyakov captured a series of nightscape images in the early morning of July 1, 2016. "The whole horizon over Nykøbing Mors from west to east was filled with silver light and it was very bright!" Merzlyakov wrote in an email to Space.com. Noctilucent clouds form in an upper layer of the Earth's atmosphere called the mesosphere, which is about 50 to 53 miles (80 to 85 kilometers) above ground.
