Back on November 23rd, the Pico do Fogo volcano on Cape Verde's Fogo island erupted. This image shows how that incident looked when it was captured by the Sentinel-1A satellite's radar sensors. Scientists are using these images to help them map the volcano's subsurface magmatic system.
This radar image of Tokyo was acquired by the European Space Agency's Sentinel-1A satellite earlier this year. The data is so accurate that it can monitor ground movements down to a few millimetres, which helps urban planners know where they can and can't build.
