It may be Good Friday, but there are always things going on in the universe. The latest Carnival of Space is up and running and always good for insightful off-planet things.
I was reading about how Titan’s landmarks are off by almost twenty miles. Features like craters, dunes, and lakes can’t be moving on their own, right? They’re not. It seems as if Titan has a global sub-surface ocean of water and ammonia. Titan’s crust is completely detached from an inner solid core.
I liked this whole globe image of Dione earlier this week:
You can see those southern cliffs cutting through a few craters.
From over 350 quadrillion miles away, a planet shows its methane to astronomers.
Salt deposits on Mars point to possible upwellings from the interior.
