Unless you've been sleeping under a comet then you must have heard about the major success the European Space Agency had last week when Rosetta's lander Philae touched down on Comet 67P/Churyumov–Gerasimenko not once, but three times.
Since then the space projectile has been heard singing into outer space. Perhaps it's trying to tell us something? What if it's singing a lonely tune? Or maybe it's singing because it's finally found a friend in Philae?
No matter what the reason (or physics) behind it, we've been playing this tune on repeat at WCIP Headquarters.
