Where are the Aliens? Interview With a SETI Researcher
Yesterday the internet was abuzz with talk about UFOs and the Roswell incident, which took place 66 years ago this week.
Discovering life beyond Earth has always been considered by some to be the holy grail of science. However, no little green men or even measly microbes have been conclusively found. But this hasn’t dampened the enthusiasm among astronomers who are still searching the cosmos for signs of extra-terrestrial life. The current leading search method uses giant radio dishes to scan the stars, listening for possible faint signals coming from distant civilizations.
National Geographic News caught up with SETI (Search for Extraterrestrial Intelligence) radio astronomer, Andrew Siemion, who is based at the University of California at Berkeley, to chat about how astronomers listen for aliens.
