Space Pictures This Week: Mars Pit, Warped Galaxy, More

Sunlight casts a crescent shadow on the floor of an underground cavern in a recently released picture of a Martian "skylight." This round opening likely leads to a lava tube, which is created when lava solidifies on the surface but keeps flowing underground. Eventually the lava drains away, leaving an empty cave.
