Titan is the perfect benchmark for studying exoplanet atmospheres, study suggests

The NASA/ESA Cassini-Huygens mission explored Saturn and its moons from 2004 to 2017, providing the most detailed images and data on the system ever taken. This included Saturn's largest moon, Titan, which the probe examined closely during its many flybys, and with the deployment of the Huygens lander to its surface.

Titan is the Perfect Benchmark for Studying Exoplanet Atmospheres

While we know of thousands of exoplanets, the science of studying their atmospheres is still in its early days. When astronomers analyze atmospheres, they have to decide which molecules to include in their models, which can bias the results. A new paper proposes that Cassini data on Titan could provide the perfect benchmark, helping to distinguish between different hydrocarbons detected in the atmosphere of an exoplanet.
