Mars's ice caps are melting, and Jupiter is developing a second giant red spot, an enormous hurricane-like storm.
The existing Great Red Spot is 300 years old and twice the size of Earth. The new storm -- Red Spot Jr. -- is thought to be the result of a sudden warming on our solar system's largest planet. Dr. Imke de Pater of Berkeley University says some parts of Jupiter are now as much as six degrees Celsius warmer than just a few years ago.
Neptune's moon, Triton, studied in 1989 after the unmanned Voyageur probe flew past, seems to have heated up significantly since then. Parts of its frozen nitrogen surface have begun melting and turning to gas, making Triton's atmosphere denser.
