Saturn's moon Enceladus is the perfect extraterrestrial ski resort

If you're tired of skiing on Earth, there's some perfect powder waiting for you, just 800 billion miles away. It's all thanks to Enceladus's amazing water geysers, some of which rain back down on the moon's surface as snow.

We've known for some time now that there are geysers on Enceladus, but it's only in the last year or so that the Cassini spacecraft has been able to fully reveal how remarkable these eruptions are. We recently discovered those geysers shoot water all the way to Saturn itself, making Enceladus the only known moon to affect its planet's climate directly. And now we've discovered how those geysers are affecting conditions back on Enceladus... and, well, it's pretty much the perfect off-world ski resort.

I say "perfect", but that is ignoring little details like the unimaginably cold temperatures and the 1% Earth's gravity, which probably would make ski jumping more dramatic than it really needs to be. But it's the snow that earns that label - Cassini has found that huge swaths of the moon are covered in snow particles, each only a few micrometers in size. The snow fields are more than 300 feet thick in places, making it some of the best snow in the solar system. Now all we need is a couple chairlifts, and we're away...
