REPORT OF THE SKY CANADA PROJECT# 17 Remote communication with extraterrestrial civilizations, if it ever occurs, will be more of a marathon than a sprint due to the vast distances between solar systems. Even signals travelling at the speed of light can take thousands of years to travel either way. The unlikelihood of another technologically advanced civilization nearby, the absence of SETI signals so far, and the immense challenges of interstellar travel are the main reasons why there is a strong consensus among scientists that UAPs are not extraterrestrial vehicles. But, as always in science, new evidence (such as SETI signals or other data) could change the prevailing scientific assessment. The search for extraterrestrial life involves several fields, in- cluding astronomy, biology and planetary science, and relies on both theoretical models and empirical evidence. Although there is as yet no evidence that life beyond Earth exists, there are reasons to be optimistic about this possibility, including: • Exoplanet Discovery: Instruments like the James Webb Space Telescope (JWST) allow scientists to analyze the atmospheres of thousands of exoplanets (planets outside our solar system). Many of them are in the “habitable zone” of their sun. • Astrobiology and Extremophiles: The discovery of extrem- ophiles—organisms that thrive in extreme conditions—has broadened our understanding of where life might exist and what extraterrestrial life might look like, especially in harsh environments. • Solar System Planets: Mars is attracting particular atten- tion due to evidence of past liquid water. NASA’s Persever- ance rover is exploring Mars for signs of ancient microbial life. Moons like Jupiter’s Europa and Saturn’s Enceladus, which have subsurface oceans beneath icy surfaces, are also considered potential habitats for microbial life. • SETI: The Search for Extraterrestrial Intelligence (SETI) uses radio telescopes to look for signals from technology-based civilizations. No signal has yet been confirmed despite several decades of research. Projects like Breakthrough Listen aim to scan millions of star systems for signs of such civilizations. • Bio- and Techno-Signature Research: Scientists are looking for observable indicators which could suggest the presence of life (bio signatures) or technology (techno signatures). These indicators can take the form of chemical markers, such as particular gases or organic molecules, that are produced by living organisms or by technological means. New models are being developed to predict what these markers might be on different types of exoplanets. Radio telescopes similar to those used by the Search for Extraterrestrial Intelligence (SETI) program, a privately funded initiative looking for signals that may have been emitted by advanced civilizations outside the solar system. 3D rendering of the James Webb Space Telescope (credit NASA), the most powerful space telescope ever built, operational since July 2022.
