NASA scientists made a groundbreaking discovery deep inside Alaskan permafrost. They defrosted 32,000-year-old bacteria frozen since the ancient Ice Age. The moment the ice melted, the microbes woke right up. They immediately started swimming, feeding, and multiplying. This shock revival proved ancient organisms can survive extreme freezing for millennia. Now, NASA astrobiologists believe similar dormant life might be waiting inside the frozen ice caps of Mars today.
