Science in Seconds - Life in Space

Science in Seconds Know Everything RAVES - Life In Space Brit Trogen: Amino acids are the building blocks of proteins and of life as we know it, and for the first time, they've been discovered on a comet. An event that's re-energizing the debate on the origins of life because it's an enormous push for the idea that life on Earth was seeded from outer space, a concept called "Panspermia". Now this doesn't mean that we were planted here by a superior alien race - sorry "Stargate". It means that life might have developed on comets or other planets and then been transferred here by inter-planetary collisions. Comets are dirty balls of ice that congregate in the outer solar system and are believed to represent material identical to what existed shortly after the Big Bang. So if amino acids exist on comets, it could mean that organic matter existed in the early solar system, and that it might even be floating around freely in the cosmos, which means that when interstellar gas clouds condense into planets, the building blocks of life might already be on them. However, life in space would have to deal with very damaging conditions like radiation and cosmic rays. And some scientists don't think there's enough carbon, nitrogen, and oxygen, or the right temperatures or conditions to allow life to emerge. So in the meantime, the debate will continue to rage. But in any case, the idea of "pre-fab" planets, ready made with the starting materials of evolution, is pretty damn cool.
