These radio waves seemed to be coming from deep space. This is an important step, because signals can often come from non-alien sources.įor example, telescopes at the Parkes Observatory in Australia once detected radio waves. When they detect an unusual signal, astronomers usually monitor the region more closely with more telescopes. What happens if astronomers detect a signal? Eventually, the ATA will use 350 individual dishes to probe the sky for signals from outer space. The Allen Telescope Array (ATA) is an example of the LNSD approach to SETI. Wide-sky surveys would make sure scientists didn’t miss out on these planets-or these aliens! Aliens might be living on completely different types of planets. But no one really knows what alien life might look and act like, or where it might live. In these cases, it makes sense to use targeted searches. Many astronomers think that it’s best to use a combination of both methods.Īstronomers believe certain planets, such as exoplanets located in Earth's “Goldilocks zone”, are more likely to have alien life. This way, astronomers can study objects in more detail. In a targeted search, astronomers point the dishes toward a specific area. Because the dishes do not focus on specific areas, they can only pick up the most powerful signals. But there’s a drawback to this technique. This way, astronomers can monitor a greater number of planets, stars and galaxies. In a wide-sky survey, astronomers scan large areas of sky. How do scientists listen for alien life?Īstronomers often use very large satellite dishes to listen for incoming radio waves. The SETI Institute is a non-profit organization dedicated to SETI. SETI - or Search for Extraterrestrial Intelligence - is the scientific practice of searching for intelligent aliens. Also, they usually aren’t blocked by the gases and dust found in space. That’s because the waves can travel such long distances. In fact, astronomers think that radio waves are an ideal way to communicate across the universe. This technique is sometimes called radio SETI. That’s why many SETI researchers search the sky for radio waves. One day, an alien civilization may receive these signals and try to contact us!

For decades, TV and radio broadcasts from Earth have been traveling into space. Humans also send radio signals into space ourselves. Maybe their radio signals end up reaching Earth by accident! Or they might be trying to communicate with each other. Alien civilizations might also be sending radio signals into space.These aliens might actually be trying to reach us. You have probably listened to music that was transmitted by a radio station near you. Sound interesting? You can help researchers sift through the data! Why Do Astronomers Listen for Radio Waves? So how exactly do astronomers look for extraterrestrial life? Mostly, they listen for radio waves (a type of electromagnetic radiation) coming from deep space. Since then, they have used many different techniques to try and answer the question: is there life beyond Earth? Still, Project Ozma sparked the interest of other astronomers. Project Ozma was named after Princess Ozma, the ruler of the fictional Land of Oz (from The Wizard of Oz). But all he heard was silence and the occasional false alarm. Astronomer Frank Drake used a radio telescope to search for signs of intelligent alien life. The first modern SETI (Search for Extraterrestrial Intelligence) project was Project Ozma, which began in 1960. People have been searching for signs of extraterrestrial (alien) life since the telescope was invented. One billionaire will partner with NASA to look for life on one of Saturn’s moons!īut you don’t need to leave Earth to look for aliens. Several billionaires have also started pouring millions of dollars into searching space for aliens. Space exploration seems to fascinate rich entrepreneurs like Tesla’s Elon Musk and Amazon’s Jeff Bezos. They were coming from the direction of HD164595, a star 95 light years from Earth! Journalists began to wonder: could these signals be from an alien civilization?
