Terrestrial caves offer scientific and engineering insights and serve as testing grounds for future forays by humans and robots into caves on other worlds.
Saturn’s moon Enceladus boasts fierce tiger stripes around its south pole, a mystery that has long puzzled scientists. New research explores the stripes by examining how the moon’s ice breaks.
New research considers the effect of Jupiter’s Galilean moons on each other’s oceans for the first time.
The electron density peaks well after the activity of the moon’s distinctive south polar ice plume reaches its maximum, but the cause of the lag remains puzzling.
The Cassini spacecraft observed spiral density waves in the rings of Saturn which can be used to probe its interior structure and rotation.
Decades of research have illuminated how Io and Europa shape—and are shaped by—Jupiter’s giant magnetosphere.
A new model is the first to simultaneously explain many of the moons’ characteristics, including their mass, orbits, and icy composition
A new study suggests alternative explanations for Io’s unusual magnetic field.
A new study finds that Phobos includes chunks of Martian crust.
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.
