00:00What if an entire moon was powered by non-stop volcanic eruptions?
00:04That world exists, and its biggest troublemaker is a giant planet.
00:08Io orbits Jupiter, whose gravity stretches and squeezes the moon.
00:12This creates heat that melts rock.
00:17The result? A landscape covered in volcanic features,
00:22with eruptions that blast material into space.
00:25This is Io.
