Pull on an extra layer and stay toasty whilst Science in Action braces for a deep freeze. Whilst we know plenty about the ice on the Earth’s poles, Roland is on a chilling journey to see what can be found in deep space.

Professor Christoph Salzmann and Professor Andrea Sella at University College London have produced a new phase of ice. Roland heads to the laboratory to see how the usual crystalline ice, found in ice cubes and icebergs, can be broken down and arranged into a new structure.

The James Webb Space Telescope has detected the coldest ices to date, deep within a molecular cloud in outer space. Professor Melissa McClure describes how these clouds harbour a variety of different molecules potentially capable of forming the basic building blocks for life.

From the edges of the universe to something a little closer to home, Professor Geoff Collins and colleagues have discovered odd tectonic plate activity on icy Europa, one of Jupiter’s moons.

And a theory for the origin of life that may surprise you. Professor Philipp Holliger is trying to uncover whether ice played a role in our creation, acting as a medium capable of concentrating molecules and promoting the chemical reactions required for the generation of RNA, essential for cell protein production.
