Photo by @estherhorvath / Moonlight over the Central Arctic Ocean, close to the North Pole. During the polar nights on the MOSAiC science expedition, we could see the moon circling above us 24 hours a day if it was not cloudy. The moonlight provided visibility, which helped with experiments at the science stations on the sea ice and with watching out for polar bears.
