Solar System round-up
It\u2019s a busy year in the Solar System for robotic explorers, with New Horizons on the way to distant Pluto, Dawn orbiting Ceres in the outer asteroid belt, and Rosetta and Philae accompanying comet 67P/Churyumov-Gerasimenko as it makes its closets approach to the Sun. This month Dr Edward Gomez and I chat about these missions, as well as some recent results about exploding stars way across the cosmos!\n\nOriginally broadcast (in edited form) on 28th May\xa02015 as part of Pythagoras\u2019 Trousers on Radio Cardiff.
