Jupiter: December 2017

Speeding through the atmosphere high above Jupiter's equator is an east-west jet stream that reverses course on a schedule almost as predictable as a Tokyo train's. Now, a NASA-led team has identified which type of wave forces this jet to change direction.

Data collected by NASA's Juno spacecraft during its first pass over Jupiter's Great Red Spot in July 2017 indicate that this iconic feature penetrates well below the clouds

A Brown University study provides new evidence that the icy shell of Jupiter's moon Europa may have plate tectonics similar to those on Earth.
