We've Found A Hidden Ocean On Enceladus That May Harbor Life

It's turning out that the outer reaches of the solar system may be more hospitable to life than we ever imagined. Gravity measurements made by Cassini have confirmed that Enceladus, a tiny moon orbiting Saturn, hosts a subsurface ocean in its southern latitudes.

When it comes to space, perspective is everything. We've talked about the importance of scale in the past – about how, when separated by millions of miles of space, many objects in our solar system can seem unrelatably gigantic. It's what makes images like this one so eye-opening. » 3/27/13 8:30am 3/27/13 8:30am

The weirdest moons in the solar system, and what it would look like to …

It would sometimes seem as though there are two solar systems: One including planets, and another including moons. Until recently, most books about the solar system focused on the planets, stopping only to acknowledge the existence of their satellites with a kind of half-embarrassed nod. They would be discussed as a… » 11/10/11 8:00am 11/10/11 8:00am

The Real, Shameful Reason We'll Explore Saturn's Moons

Exploring the moons of Saturn and Jupiter could show us habitable worlds, liquid water, and perhaps even alien life. But webcomic Saturday Morning Breakfast Cereal suggests that the real reason we'll visit Enceladus won't be for scientific exploration. » 12/30/09 9:30am 12/30/09 9:30am
