![]() ![]() We know that it is possible to become an old technology. Tarter told NPR (Opens in a new window) that "We don't know how to identify intelligence over interstellar distances, so what we do instead is use technology for a proxy if we detect a signal, we know that it is possible to survive our technological adolescence. Ellie Arroway, played by Jodie Foster, in the 1997 film Contact) has been searching for anomalies in space signals since 1977, at both NASA and SETI ( which PCMag visited in 2018). Of course, if they do, the microbes could inadvertently hitch a ride, but more on the risk of interplanetary pathogens in a moment.Īstronomer Dr. The latter might be sufficiently advanced to create an interstellar craft. The other question is whether life forms, if they exist on those exoplanets, are microbes or mathematicians. What's the Sci-Tech Protocol for First Contact? But is there life out there as we know it? And does it know we’re here? Nathalie Cabrol pointed out in her paper Alien Mindscapes-A Perspective on the Search for Extraterrestrial Intelligence (Opens in a new window), “powerful evidence that our solar system is not an exception but simply one out of countless others in the universe.” So we’re not (totally) unique. To extend Hubble’s work, the James Webb Space Telescope has already sent back incredible images, including an infrared analysis of a planet outside our solar system.Īs for how many of those galaxies have planets that could support life, NASA's Kepler and K2 (Opens in a new window), followed by TESS (Transiting Exoplanet Survey Satellite) (Opens in a new window), took on the mission “to discover hundreds of Earth-size and smaller planets in or near the habitable zone and determine the fraction of the hundreds of billions of stars in our galaxy that might have such planets.” JPL/Caltech planetary scientists are keeping a running tally at the NASA Exoplanet Archive (Opens in a new window).Īstonishingly, 5,178 exoplanets have been identified so far. The Hubble Space Telescope’s furthest observation is 13.4 billion light years away and, deploying its deep field imagery, has identified (Opens in a new window) 10,000 galaxies so far, and counting. We're still looking, but now we have technology advanced enough to start reporting back. According to NASA (Opens in a new window), "the visible universe has a radius of about 15 billion light years or 300,000 times the size of the Milky Way." That’s a lot of space.
