The Rosetta spacecraft is currently orbiting and exploring comet 67P/Churyumov-Gerasimenko—a large mass of rock and ice that it landed the Philae probe on in November —and its newest discovery might give us startling insight about the origin of water on our own planet. It has been discovered that comet’s water contains three times the amount of deuterium than water here on Earth, which throws a wrench into theories that t his planet’s oceans and rivers  may have originated from comets slamming into it during its formation.
