Earth’s astronomers and scientists use radio telescopes to listen to signals from space for extraterrestrial life, but Earth’s own signals have become too quiet for the rest of the universe to hear us, even from the closest stars. Speedify engineers discuss how humanity’s radio signals have become harder to detect over time, and what that means for finding intelligent alien life beyond Earth. As Carl Sagan once said, “The universe is a pretty big place. If it’s just us, seems like an awful waste of space…”.
We explore SETI’s search for unexplained signals, future radio telescopes on the far side of the Moon, and recent asteroid samples that reveal the building blocks of life.
