The Philae lander has detected organic molecules on its comet! Wait, let me properly emphasize that: PHILAE HAS FOUND THE MOLECULES OF LIFE ON A COMET.

This could finally prove that life on Earth originated from material comets spewed across the Solar System back during the planet’s late formative years. The theory goes thus: When comets smashed into the lifeless Earth, they caused dramatic and complex chemical reactions that formed the building blocks of life.

We are LITERALLY made of star-stuff.
