Future space missions will further our knowledge of tidal heating and orbital resonances, processes thought to create spectacular volcanism and oceans of magma or water on other worlds.
A new model is the first to simultaneously explain many of the moons’ characteristics, including their mass, orbits, and icy composition
The first in-situ ion observations from NASA’s Juno spacecraft reveal the surprising, simultaneous presence of cold protons and hot oxygen and sulfur ions in the high-latitude ionosphere of Jupiter.
The gas giant’s interior reveals evidence of an ancient impact.
The first movie of Jupiter’s infrared aurora gives scientists a new look at the Jovian magnetic field.
Force imbalance between Jupiter’s ionosphere and magnetosphere leads to wave generation to release this stress, but the waves also accelerate particles, causing aurora and heating.
The newly plotted moons of Jupiter include one “oddball” that orbits in the wrong direction and may be the remnant of a head-on collision.
Japan’s Hisaki satellite takes measurements of faint oxygen emissions from Io.
Deep clouds, polar storms, lopsided gravity, and a uniformly rotating interior demonstrate that the gas giant plays by different rules than Earth.
Jupiter’s moon Io is known for its lava fountains and roiling lava lakes, but scientists had never seen such an intense eruption in their data until now.
