Big Picture Science – It’s Habitable Forming

There’s evidence for a subsurface lake on Mars, and scientists are excitedly using the “h” word. Could the Red Planet be habitable, not billions of years ago, but today? While we wait – impatiently – for a confirmation of this result, we review the recipe for habitable alien worlds. For example, the moon Titan has liquid lakes on its surface. Could they be filled with Titanites?

Dive into a possible briny, underground lake on Mars … protect yourself from the methane-drenched rain on a moon of Saturn … and cheer on the missed-it-by-that-much planets, asteroids Ceres and Vesta.

Also, do tens of billions of potentially habitable extrasolar planets mean that Earth is not unique?
