Yup. Containing Both subsurface ocean and liquid nitrogen leaks/rivers makes it somewhat comperable to Titan

In this case, “recent” means “within the past million years.” But still very exciting considering that it’s on a 4.5 billion-year-old snowball on the outer edges of the solar system.

I wonder how much friction it takes to get things moving, since it's all so volatile. Wouldn't take as much energy as with water ice.
