Jüri Voit has been a long-time friend of EarthSky on Facebook, and he’s posted many wonderful photos there from his native country of Estonia, in northern Europe. Here is his latest, taken on July 6, 2015. It’s a beautiful shot of noctilucent clouds, sometimes called “night-shining clouds” because they shine at a night.

Thank you, Jüri!
