![]() ![]() The University of St Andrews has joined forces with the UK SETI (Search for Extraterrestrial Intelligence) Research Network to establish protocols and procedures if aliens are found. There is no choice but to search and see what we find, because the implications would be tremendous.Aliens could get in touch tomorrow and we must know what to say to them, scientists have warned, as they launched a new research hub to prepare humanity for first contact. “For that reason we cannot know whether these searches have any chance of success. “We have no idea whether intelligence is something very common in the Universe or, on the contrary, whether it is extremely rare,” said Hector Socas-Navarro, an IAC researcher, the Director of the Museum of Science and the Cosmos, of Museums of Tenerife, and the first author of the paper. ![]() It’s therefore something of a free hit, according to the researchers-the modern search for aliens can be all about synergy.Ī free hit it may be, but it could also be a fruitless one. The next generation of telescopes- such as the James Webb Space Telescope (JWST), but many others-will also, for the first time, allow a search for so-called biomarkers, evidence for life on other planets. While characterizing the atmosphere of an exoplanet it will by default detect the presence of, say, CFCs or nitrogen dioxide. That’s exactly the same science that needs to be done to search for technosignatures. Rafael Luis Méndez Peña/įor example, many space telescopes and survey satellites-such as TESS-observe stars to see if exoplanet are transiting across them. In fact, the renewed interest in “technosignature science” is largely down to the fact that it can be done purely by taking advantage of data that is already being collected astronomical purposes.Īrtistic recreation of a hypothetical exoplanet with artificial lights on the night side. Scale and scope is tricky since a search for crashed spacecraft on the Moon could easily be done, whereas a search for Dyson spheres in our galaxy would have a billion potential targets, according to the paper.ĭon’t get the idea that armies of astronomers and NASA scientists are spending their days and nights searching for traces of extraterrestrial intelligence. ![]() The researchers call this an “ichnoscale.” It’s a measure of how easy to see a technosignature might be from a huge distance. The study puts forward a plan, and a new way of classifying the technosignatures as a function of their “cosmic footprint”-the relative size scale of a given technosignature in units of the same technosignature produced by current Earth technology. “This does not necessarily mean that any extraterrestrial technology must be like our own, but imagining plausible extensions of our own future is one place to begin thinking of astronomical searches we could actually do to look for possible technosignatures.” MORE FROM FORBES Self-Destruction Of $1.4 Billion Spacecraft At Jupiter Scrubbed By NASA As It Returns More Stunning Images By Jamie Carter “The idea of searching for technosignatures draws upon the technology we have on Earth today and possible extensions of our technology into the future,” said Jacob Haqq-Misra, a co-author of the article and chairman of the TechnoClimes 2020 organizing committee. So we’re looking for massive, unmistakable signs of alien civilisations far more advanced that we are. “Only those species that have constructed or developed technology is much larger or more luminous than any of our own can be detected with our current astronomical infrastructure.” “For us to detect such signals at interstellar distances with our current sensitivities, such signals would need to be stronger than those produced by current human civilization, particularly the unintentional ones,” read the paper.

In short, we don’t yet have instruments sensitive enough to definitively find “another Earth” by detecting an alien civilization outright. ![]()
