The SETI programme began in the 1960s and aims to find extraterrestrial life by listening to radio waves and laser signals from space. Scientists use huge radiotelescopes, such as the Arecibo Observatory, to scan the skies for possible signs of alien civilizations.
However, there are many challenges. Aliens might not use radio technology, making it impossible to detect their signals. Also, with billions of stars and countless radio channels, it can take a very long time to find anything. Signals from distant civilizations could take thousands of years to reach Earth. So far, no confirmed evidence of alien life has been found.
You can help with the search by joining the SETI@home project. By downloading a special screensaver, your computer will analyze data from radio telescopes when you are not using it. Millions of people around the world already participate in this project, helping scientists in the search for intelligent life beyond Earth.
