People used to think comets were warnings of disasters. Today we know that they are icy visitors from the most distant regions of the Solar System. Other stars have exoplanets and they seem to have exocomets too.
Who was really the first to orbit Earth? What is Snoopy's role in the manned space program? What sent an Australian teenager rushing to San Francisco? Which stars are Dnoces, Navi and Regor? Find out all of this . . . and more!
The Solar System's large moons tend towards the weird and wonderful, and Triton is no exception. It has ice volcanoes, a strange “cantaloupe terrain”, and crazy seasons. It's the only large moon to orbit in the wrong direction, so it didn't form near Neptune. But where did it come from?
