![Pressures determined by ruby fluorescence measurements at different locations within the sample chamber: (a) during powder compaction, (b) after decompression. No ruby fluorescence spectrum was obtained on the sphere marked with an asterisk, likely due to insufficient Cr doping, resulting in an undetectable fluorescence signal. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/Elastic.png?resize=1200%2C720&ssl=1)
[astro-ph.EP] Titan tholins, complex organic solids synthesized by simulating photochemical processes in Titan’s atmosphere, are widely regarded as analogs to organic surface materials on the Saturnian moon.

The Enceladian Crater Production Function
[astro-ph.EP]. Interpreting Enceladus’s past and present surface history and interior state remains challenging, owing to uncertain prescription of its impact bombardment history and limited interpretation of its crater statistics. Further […]

The Mystery Of Titan’s Missing Deltas
For scientists who want to learn about the geological history of a planet, river deltas are a great place to start. Deltas gather sediment from a large area into one […]

Liquid On Mars Was Not Necessarily All Water
Dry river channels and lake beds on Mars point to the long-ago presence of a liquid on the planet’s surface, and the minerals observed from orbit and from landers seem […]
