Astronomers have developed a new method of detecting extraterrestrials — Science and IT
However, astronomers warn that aliens may use completely different methods of communication.
Scientists have been trying to find signals from extraterrestrial civilizations for more than 50 years, but so far without success. A new study published in The Astronomical Journal suggests a way to “eavesdrop” on radio conversations between planets outside the solar system. Popular Mechanics writes about it.
Researchers suggest using exoplanet eclipses — the moment when one planet passes in front of another. At these moments, radio signals transmitted between planets can be recorded by ground-based radio telescopes.
Narrowband radio signals that can be found using this method are considered artificial, because only humans are currently known to be able to create them. Such signals may indicate the presence of communication between alien civilizations, even if…
