SWRI

SwRI is studying how Saturn's largest moon maintains its dense atmosphere. Scientists think Titan's core is covered in layers of ice and a subsurface liquid ocean. New experiments show that nitrogen and methane gases produced by organic matter in the core seep to the surface, regularly renewing the atmosphere. Credit: Southwest Research Institute

Scientists decipher Titan's dense atmosphere – new discoveries about the sources of nitrogen and methane

New research suggests that nitrogen and methane seep from Titan's rocky core to the surface, helping to maintain its dense atmosphere. The findings could shed light on the planet's internal chemistry.
This illustration shows charged particles from Jupiter hitting the face of Europa, separating icy water molecules into hydrogen and oxygen molecules. The scientists believe that some of these newly formed oxygen gases can move into the moon's subsurface ocean, as the circled figure shows. Credit: NASA/JPL-Caltech/SWRI/PU

Will the moon Europa return? The Juno spacecraft discovered oxygen on Jupiter's moon

NASA's Juno spacecraft directly measured charged molecules of oxygen and hydrogen from the atmosphere of Europa, one of Jupiter's largest moons. According to new research by scientists at SwRI and Princeton, these observations provided
