TRAPPIST-1 Alien Radio Signals: Chinese Search
- China's FAST telescope conducted a large-scale search for extraterrestrial intelligence (SETI).
- * Sensitivity: FAST was able to detect incredibly faint signals (as weak as 2.04×10^10 watts), more sensitive than previous SETI efforts.
Here’s a summary of the provided text:
China’s FAST telescope conducted a large-scale search for extraterrestrial intelligence (SETI). The telescope, the world’s largest single-dish radio telescope, was used to look for specific, artificially-produced radio signals that would change over time due to planetary motion.
Key points:
* Sensitivity: FAST was able to detect incredibly faint signals (as weak as 2.04×10^10 watts), more sensitive than previous SETI efforts.
* Signal Type: The search focused on signals that would be tough to create naturally,suggesting an smart source.
* No Detection: The article doesn’t state whether any signals were detected, only that the search was conducted.
* Related Research: The article links to another LiveScience article about the James Webb telescope and the search for alien life.
