SETI: Are We Alone?

For over 50 years, SETI has been searching for extraterrestrial life by scanning the universe for signals. The Allen Telescope Array is a key tool in this search, designed to detect signals from alien civilizations. In 1977, the WOW signal was detected, causing excitement but never found again. Despite this, SETI continues its efforts, focusing on Earth-like planets as new technologies and discoveries emerge, driven by the belief in the existence of intelligent life elsewhere in the universe.
