Top experts in the field of searching for extraterrestrial civilizations (SETI) have recently explored how humans will make in detecting extraterrestrial signals, including the possibility and timing of finding intelligent extraterrestrial life, according to space networks. Seth Shostak, a senior astronomer at the SETI Society in Mountain View, Calif., says next year is unlikely to be the first year of extraterrestrial life, but it’s still exciting and optimistic because multiple existing projects will be expanded or improved by 2020.
Moreover, the search for extraterrestrial life is now largely through examination of nearby star systems, narrow-frequency radio signals or short-flash lasers – projects that can be successful at any time.
“The search rate is growing exponentially, and in fact it is possible to roughly estimate when SETI will succeed. This goal will be achieved within the next 20 years. Shostak said.
Michael Michoa can be skeptical about determining which year will make his first discovery, because similar predictions have been made before, but all are wrong. It can only be said that the continuous improvement of search techniques and strategies may increase the chances of success.
Mr Micho said the main focus of SETI remained radio signals, and “we still don’t cover all frequencies and all space-time ranges.” Other types of searches have not been successful, such as looking for laser signals or ‘Dyson balls’. Dyson Ball is thought to be an artificial object that wraps stars and exploits their energy.
As a result, “astronomers can first look for chemical evidence of life in the planet’s atmosphere.” Before we can discover signals from technological civilization, we may first discover simple life forms. Michont said.
Steven Dick, an astrobiologist and science writer, says that now we have tess telescopes, breakthrough initiatives, breakthrough listening, and research to detect biometrics, “all of which add up to increase the chances of discovering intelligent life from extraterrestrials over the next decade.”
In addition, the SETI Society will install new receivers for the Allen Telescope Array in Northern California, and SETI and Berkeley will conduct new searches for possible signals.
