For the first time in more than a century, scientists have identified new sodium chloride crystals. The discovery may reconcile puzzling spectroscopic images of Europa’s surface.
Marine Science Goes to Space
Space and ocean scientists take a splash course in multidisciplinary science to chart our solar system’s ocean worlds.
Europa’s Plate Tectonic Activity Is Unlike Earth’s
The moon of Jupiter has likely experienced intermittent, regional plate tectonic activity in the past, although the plates are currently dormant.
Zipping Up Data to Zap It Back from an Icy Moon
NASA wants to send instruments to distant moons like Europa and Enceladus to search for life. But getting vital data back to Earth over limited bandwidth will take some impressive compression software.
Dynamics of Ocean Worlds Likely Controlled by Their Rotation
New simulations suggest that subsurface oceans on icy moons with small natural Rossby numbers may be dominated by rotational effects.
Lipids from Europa’s Ocean Could Be Detectable on the Surface
A super salty spring in the Canadian Arctic provides insights key to detecting life on a distant ocean world.
Europa’s Ocean Can Tug Its Ice Shell Around
Sometimes ocean dynamics are a drag.
New Energetic Neutral Atom Emissions from Jupiter, Io, and Europa
The first Jovian off-equator Energetic Neutral Atom viewings reveal distinct emissions from Jupiter and the orbits of Io and Europa: Energetic particle injections surprisingly occur inside Io’s orbit.
Two Moons and a Magnetosphere
Decades of research have illuminated how Io and Europa shape—and are shaped by—Jupiter’s giant magnetosphere.
