An aerial view of the edge of the Ross Ice Shelf, in Antarctica, in 2017. Scientists are racing to understand what is happening to the ice shelf as the planet warms around it. They are also trying to measure the role of human-caused climate change in weakening other parts of the West Antarctic ice sheet, and to fathom how damaging warming seas and changing wind patterns might ultimately prove to be.

A handout image shot with the Cassini spacecraft’s camera of Enceladus, one of Saturn’s moons, across the unilluminated side of Saturn's rings, taken on Oct. 27, 2007. After 13 years of researching and imaging the ringed planet and its many moons, NASA will end the mission in September 2017. The spacecraft will fly into the atmosphere of Saturn and burn up.

Artist's concept depicts an itsy bitsy planetary system -- so compact, in fact, that it's more like Jupiter and its moons than a star and its planets. Astronomers using data from NASA's Kepler mission and ground-based telescopes recently confirmed that the system, called KOI-961, hosts the three smallest exoplanets known so far to orbit a star other than our sun.
