Jupiter

NASA's Juno spacecraft will come closer to Jupiter's moon Io on Dec. 30 than any spacecraft has in 20 years, getting a good look at the solar system's most volcanic body.

The spacecraft recently burned 10 percent of its total fuel in a single 43-minute maneuver as preparation for the double gravity assist.

Jupiter's moon Io, the most volcanically active world in the solar system, may possess a global ocean of magma underneath its surface, as well as mysteriously warm poles, a new study finds.

NASA's Juno spacecraft has found that Jupiter's winds whip around the planet's turbulent atmosphere cylindrically.
