Ever since the Cassini probe spotted a geyser of ice and water spewing from the south pole of the Saturnian moon Enceladus, there’s been a lot of speculation as to why this particular spot should be the site of the outgassing materials. Certain scientists believe the hotspot may have started elsewhere, and that the laws of physics made the moon tilt to its current orientation. This could mean that there are, as hoped, oceans beneath the ice, but not everyone agrees with the hypothesis. As always, more data is required.
