Space SnapshotWelcome to the labyrinth of night. The hauntingly-named Noctis Labyrinthus is a fascinating region near the equator of Mars, pictured here in an image from ESA’s Mars Express orbiter. It’s home to a network of intersecting canyons, some as deep as 6 kilometers (3.7 miles). The canyons were likely created by past volcanism in a nearby area, which would have caused the planet’s surface to arch upwards and then collapse. Image credit: ESA / DLR / FU Berlin.
