Part 7/10:
Examining Exoplanets: Using telescopes to study planets orbiting distant stars, searching for biosignatures such as oxygen, water vapor, and carbon dioxide—indicators of potentially life-sustaining environments.
Searching for Technosignatures: Listening for and transmitting signals that could reveal technologically advanced civilizations capable of communication across cosmic distances.
The "Wow! Signal" stands as one of the most intriguing examples of potential technosignatures, evoking hope that intelligent life beyond Earth may have already attempted to reach out. Still, despite numerous signals detected over the decades, concrete proof remains elusive.
