"New Tools and Radio Array Boost Search for Alien Life"
The Search for Extraterrestrial Intelligence (SETI) has been attempting to detect electromagnetic signals from alien civilizations for six decades. Although no transmissions have been discovered yet, astronomers continue to make attempts using powerful new tools. The motivation behind such signals could be for navigation, entertainment, or to see if anyone is home in our solar system. The history of SETI dates back to 1960 when astronomer Frank Drake aimed an 85-foot antenna at two nearby star systems, sparking public excitement and further attempts.
