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.
Jupiter
Jupiter’s Galilean Moons May Have Formed Slowly
A new model is the first to simultaneously explain many of the moons’ characteristics, including their mass, orbits, and icy composition
First Inside Look at Hot and Cold Ions in Jupiter’s Ionosphere
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.
Massive Collision Cracked Young Jupiter’s Core
The gas giant’s interior reveals evidence of an ancient impact.
Jupiter’s Northern Lights on Display in Otherworldly Movie
The first movie of Jupiter’s infrared aurora gives scientists a new look at the Jovian magnetic field.
Jupiter’s Stressed Out Magnetosphere Causes Aurora and Heating
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.
Ten New Moons Discovered Around Jupiter
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.
The Oxygen Neutral Cloud Surrounding Jupiter’s Volcanic Moon
Japan’s Hisaki satellite takes measurements of faint oxygen emissions from Io.
New Juno Data Reveal Four Key Secrets of Jupiter
Deep clouds, polar storms, lopsided gravity, and a uniformly rotating interior demonstrate that the gas giant plays by different rules than Earth.
Scientists Discover Stromboli-Like Eruption on Volcanic Moon
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.
