How exactly life got started here on Earth is a great mystery that has spawned countless scientific theories. The possibility that at least some of the vital Building Blocks for life were delivered by comets is one such line of thinking, and is also one of the reasons the Rosetta spacecraft has been circling comet 67P/Churyumov-Gerasimenko since 2014. The probe has now discovered evidence that key amino acids and molecules do indeed exist in the comet's atmosphere, throwing further weight behind the idea that these icy trailblazers can double as life-giving space couriers.
