One of the most popular areas of science – and one that is often aimed at getting children interested in a life of empiricism – is rocket science, space exploration and all things cosmic. It can also be as fun for adults, while retaining complexity and scientific accuracy. Helen Keen's popular BBC radio programme exemplifies this approach by packing comedy and science side by side for a thoroughly enjoyable listen. Available in podcast form, it features actor Peter Serafinowicz's delightful take on the commanding tones of Patrick Stewart as The Voice of Space. It's out of this world.
