Titan’s Methane-filled Ice Layer Revealed

Share

New research suggests that Saturn’s moon Titan has a thick ice cover that could be warming lower areas and supporting molecular growth. Scientists from the University of Hawaii found this information. They studied Titan using data from NASA’s Cassini spacecraft. The researchers discovered that Titan has a thick layer of solid water ice with methane gas trapped inside. This icy crust is believed to warm Titan’s interior, causing changes to its surface structure. The surface temperature of Titan is extremely cold at about minus 179 degrees Celsius. Despite the cold, the methane gas trapped within the ice could help warm surface levels. This could support the rise of molecules toward the surface. NASA plans to send another spacecraft to Titan in 2028 to gather more information. Titan is an important place to study how methane affects atmospheres, providing insights for Earth as well.
