Does All Life Have DNA?

From StarTalk.

We take a look at NASA’s Europa Clipper mission, which will perform flybys just 25 kilometers above the moon’s surface, the hosts marvel at the engineering feat of sending a spacecraft so far from Earth. Discover how The Clipper’s onboard instruments will give us an unprecedented glimpse into the chemistry of Europa’s hidden ocean, analyzing plumes of water vapor that escape through cracks in the ice. Could we find more than just water down there—perhaps even signs of life?
