In his recent feature “Exploring the icy moons of the solar system” Keith Cooper discussed the blue “tiger stripe” cracks that are visible in images of Enceladus – fractures in the moon’s surface where water is pushed out from an underground ocean. We chose one of the spectacular images from that article for our first interactive jigsaw puzzle
There are two difficulty settings: choose between an 88-piece jigsaw and the 40-piece version.
