Enigmatic planet Mercury posed for some closeups when the BepiColombo mission flew by. Craters, bright regions and volcanic plains star in the best views from the flyby.

BepiColombo made its sixth and final flyby of Mercury on Wed (Jan. 8) capturing images of the tiny planet hinting at the mysteries it will soon investigate.

The European and Japanese robotic explorer swooped as close as 183 miles (295 kilometers) above Mercury’s night side before passing directly over the planet’s north pole. The European Space Agency released the stunning snapshots Thursday, showing the permanently shadowed craters at the top of of our solar system’s smallest, innermost planet.
