watched Inexplicable Universe e3

Watched Inexplicable Life, the third episode of The Inexplicable Universe. A few laugh-out-loud moments with Professor Tyson. And the very intriguing aspect of molecules, their "handedness." I have never heard of chiral molecules (or I don't remember learning about chirality chemistry). It's astonishing that organic molecules found in asteroids are split evenly; but on Earth, all are one type.
