COMET BORISOV just showed up in our solar system, only the second INTERSTELLAR OBJECT known to visit us! What is it, where does it come from, where's it going and will Earthlings be able to study it before it vanishes forever?

What The IF you could RIDE the comet? That'd be a heck of a way to learn about it! This week we imagine being passengers exiled from our home world, sent on an eternal cometary road trip... and, wow, we've got a sight seeing trip about to happen like no other. Look at that fine yellow sun, and what's that blue planet up ahead? Can we get off this flying snow ball? Hold on tight while we have a wild ride through the SCIENCE of Comet Borisov!
