Cassini Sees Sunny Seas on Titan

Photo courtesy JPL/NASA As it soared past Saturn’s large moon Titan recently, NASA’s Cassini spacecraft caught a glimpse of bright sunlight reflecting off hydrocarbon seas. In the past, Cassini had captured, separately, views of the polar seas and the sun glinting off them, but this is the first time both have been seen together in the same view.

JPL’s Cold Atom Laboratory Chills Atoms to New Lows

Artist’s concept of an atom chip for use by NASA’s Cold Atom Laboratory (CAL) aboard the International Space Station. CAL will use lasers to cool atoms to ultracold temperatures. Image Credit: NASA  JPL’s Cold Atom Laboratory (CAL) mission has succeeded in producing a state of matter known as a Bose-Einstein condensate, a key breakthrough for the instrument leading up to its debut on the International Space Station in late 2016. A Bose-Einstein condensate (BEC) is a collection of atoms in a dilute gas that have been lowered to extremely cold temperatures and all occupy the same quantum state, in which…
