Scientists explore the most unique corners of our world. They survey the frigid waters underneath the edge of Antarctica, watch polar bears circle as they look for a patch of ice to rest on, and gaze up at the stars from the high altitude Chilean desert.
They're able to capture some pretty stunning photos while they do all that.
Check out a selection of the finalists and winners below.
