Will We Ever Detect Alien Life?

We have spent sixty-five years pointing the most powerful instruments humanity can build at the sky, and we still cannot answer the simplest question we have ever asked. Tonight we walk slowly through the strangest gap in modern astronomy — the space between knowing life is probably out there, and being able to point at one specific case and prove it. We move through atmospheres a hundred light-years away, plumes from icy moons in our own solar system, and a rock on Mars we may never bring home. Settle in, get comfortable, and let the question keep you company until you drift off. #sleepdocumentary #alienlife #astronomy #astrobiology #cosmos #spacescience
