Dangerous volcanoes, disappearing oceans, new planets and the counterintuitive idea that rare animals may be surviving thanks to farming, that is all in this week's Science in Action with Jon Stewart.

In this week's Science in Action we are on a planetary exploration mission, looking at both our own and other worlds.

It is often said that we know more about the surface of the moon that we do about the bottom of the ocean, now new research suggests we may be wrong in our assumptions about how deep it is.

Kepler 22-b is a newly discovered planet. We ask whether it is really a mirror earth. It is orbiting around another sun, but what of the atmosphere and surface temperatures?

And we look at how agriculture in Asia and Latin America seems to be helping to preserve some rare animal species.
