Is the truth out there? How the Harvard-based Galileo Project will search the skies for alien technology

ESOCan we find alien technology? That is the ambitious goal of the Galileo Project, launched this week by Harvard astrophysicist Avi Loeb with substantial private financial backing. The project is far from the first attempt to detect signs of civilisations beyond Earth. Loeb has been criticised in the past for his dismissive approach to previous efforts to find extraterrestrial life and his argument that an alien artefact passed through our solar system in 2017. So why do Loeb and his collaborators think they have a chance of finding something where others have failed? There are three triggers that suggest they might. Exoplanets, ‘Oumuamua, and UFOs First, years of painstaking observations have shown that many stars host Earth-like planets. There is a real chance these “exoplanets” might be home to alien civilisations. Second, five years ago, an interstellar visitor, dubbed ‘Oumuamua, tumbled though our solar system. It was a skinny object about 400 metres long, and we know from its speed and trajectory that it arrived from outside our solar system. It was the first time we had ever seen an interstellar object enter our neighbourhood. Unfortunately it caught us on the hop, and we didn’t notice it until it was…
