For only the second time in history, a meteorite has been first tracked falling from space and then retrieved. The fragments landed in a remote part of Botswana, where wildlife and rough terrain made retrieving them a tough job – but it was worth it. Alexander Proyer and Fulvio Franchi explain how every meteorite is a piece of the puzzle as we try to understand our solar system.
And in other stories, explore the debate over UNESCO World Heritage status, the awkward truth about shrinking penis syndrome, and the science of scoring in a penalty shootout.

If any game comes down to a penalty shootout then there's one spot a player should aim for to stand a better chance of scoring a goal.
