Astronaut Tim Peake of the European Space Agency photographed rare, high-altitude noctilucent or “nightshining” clouds from the International Space Station (ISS) on May 29, 2016.
Noctilucent clouds – glowing silver-blue – sometimes light up summer night skies. Astronauts can see them from orbit. Here on Earth, noctilucent clouds are seen at high latitudes – say, about 45 degrees N. or S. – from May through August in the Northern Hemisphere and from November through February in the Southern Hemisphere. In 2016, the northern noctilucent cloud season has already begun.
