"The Blue Marble" is a famous photograph of the Earth taken on December 7, 1972, by the crew of the Apollo 17 spacecraft en route to the Moon at a distance of about 29,000 kilometres (18,000 mi). It shows Africa, Antarctica, and the Arabian Peninsula.


How do new elements enter the periodic table? How much does the earth weigh? Could Jupiter blow up? We tackle these explosive questions on this weeks show as well as reveal the workings of the internet and how it was created, investigate how the government could spy on our phone calls, and discover why our fingers go wrinkly in the bath!
