This isn’t the surface of another planet. In fact, it’s a flase-color image of Canada’s Manicouagan Crater, as captured by the European Space Agency’s Sentinel-1A satellite.
Created over 214 million years ago, the crater—which you can see clearly on the right of the image—is one of the oldest and largest impact craters on the planet, measuring 100 kilometers across. The image was captured by Sentinel-1A’s radar sensing equipment, and the different colors reveal variations in land cover: blue areas are particularly wet or icy, while yellow and orange regions are covered by ageing vegetation (fresh vegetation would usually show up in red).
