SETI
Researchers at the SETI Institute suggest that solar wind and plasma from stars could distort radio signals from distant intelligent life, making them harder to detect. This means past searches may have overlooked potential evidence by focusing on narrowband signals. Adjusting detection methods could improve future chances of discovery.

New research suggests the closest technological civilization in the Milky Way could be about 33,000 light years from Earth. For such a society to coexist with humanity, it would need to have endured for at least 280,000 years. The findings, presented at a joint meeting in Helsinki, underscore the rarity of extraterrestrial intelligence.
