Cassini Huygens

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

  • No comments
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.

Saturn's moon Enceladus. At the bottom of the image is its south pole, with its leopard stripes, from which water jets emerge, originating from an ocean of liquid water hidden beneath an outer layer of ice. New research suggests that this layer of ice is much thinner than previously thought in the south polar region, which could greatly assist a future lunar exploration mission.

One of the new close-up photos taken by Cassini on December 18, 2016. This photo shows part of Cassini's A ring, the outer of its two large rings, and is approximately 134 km from the planet. The photo was taken from a distance of 56,000 km . On the left side of the image you can see the route known by NASA as "straw", caused by small clusters of the tiny ice particles that make up Saturn's rings. The straw itself is visible on top of waves in the ring, which are created by the gravitational influence of the moons Epimetheus and Janus. In the rest The image shows the gravitational "traces" of the moon Pan.Source: NASA/JPL-Caltech/Space Science Institute.
