Episode number two of our podcast is out now. In this episode we have an interview with Stuart Clark about the Tunguska event that happened 100 years ago this June. It’s thought that a comet devastated large parts of Siberia when it exploded over a vast expanse of forest in 1908, felling 80 million trees! Stuart investigates the importance of this event and the mystery that surrounds it for our cover feature, in the magazine, this month. Lots more in the podcast too including my interview with Paul Money about June’s stargazing highlights, storms on Saturn and how to become and astronaut. Listen to it here.
