Summary:
- Scientists are changing their approach to the search for extraterrestrial life, focusing more on detecting biosignatures in the atmospheres of exoplanets rather than relying solely on detecting radio signals.
- This shift is driven by the realization that advanced alien civilizations may not necessarily use radio technology, and that biosignatures in planetary atmospheres could provide more direct evidence of life.
- The article discusses the potential for future space telescopes, such as the James Webb Space Telescope and the Extremely Large Telescope, to detect these biosignatures and revolutionize the search for life beyond Earth.
