There is a theory that scientists once dismissed as absurd - that long ago the Earth became so cold every inch of it was entombed in ice. The whole planet became one vast snowball lasting for ten million years. Naked Science probes this controversial theory, looking at the proof of global glaciations in the hot, dry deserts of South Australia. We investigate the theories of how our planet entered this deep freeze and how life could have survived this global catastrophe and what caused it to end? Some even suggest that Snowball Earth brought about the evolution of multi-cellular life form and we look at what would happen to our lives if the ice was to return.

Season 5, 7 episodes

We breathe it every day, it protects us from solar radiation, controls our weather – it’s the atmosphere. Naked Science takes a trip from the earth to near space to understand how the earth’s atmosphere affects all life on the planet.

Mars our closest neighbor now a lifeless planet – but it may once have had water and therefore life. Naked Science investigates the red planet to learn how it was formed, how it became barren, and ask whether it ever will be possible to colonize it?

Saturn is the second-largest planet in the solar system. Storms on this gas giant can cover an area bigger than the United States Clouds of the gas race around the planet at over 1000 miles per hour generating fierce electrical storms and lightning. Naked science investigates this planet using the latest footage from the Cassini mission to understand more about this beautiful but deadly world...
