This photo of the Wishing Well open galactic star cluster was taken a record-breaking 3.79 billion miles away from Earth by NASA’s Pluto-grazing New Horizons spacecraft. (The runner-up, by Voyager, was taken a paltry 3.75 billion miles away.)

NASA’s Curiosity rover sent back this image of a Martian rock. On its surface, geologists identified star- and swallowtail-shaped crystals; back home on Earth, such shapes are found in gypsum after salt water evaporates. The water mystery continues….
