When and how can aliens contact us? New study suggests answer

Scientists are still looking for signs of alien life on other planets. But how can we know if they are ever trying to get in touch? Can we predict when they might make contact? A new study indicates that extraterrestrial beings may be waiting for a cosmic version of ‘high noon’ to send signals of their existence. Why so? A report in Live Science suggests that in one study, researchers are finding technical signals when an exoplanet passes directly in front of their Sun. For those unaware, exoplanet is the term used to refer to any planet outside our solar system.

From Earth’s perspective, experts suggest that these precise moments are perfect opportunities for an alien world to send signals to Earth if they ever want to make contact. Study leader, Sophia Sheikh, explaining why this is the best chance to beam the signal, said it would be easy to calculate by both the parties on Earth and also at the observer’s end. “Exoplanetary transits are special because they can be calculated both by us on Earth as observers, and also by any potentially technogenic species in the exoplanetary system as transmitters,” Sheikh said. Search for Extraterrestrial Intelligence (SETI) Institute.

The study claims that these are predictable and repetitive transits in which aliens can send messages and people on Earth can receive and anticipate them. Shaikh further explained that the new study’s strategy could help them understand the million-dollar question of when and where to look for the signal across a vast region of space.

It was on 9 December when the new research was published on the preprint site arXiv. If reports are to be believed, the study is now scheduled for peer-reviewed publication in The Astronomical Journal. One of the limitations of this research is that it only includes about a dozen distant planets so far. Perhaps, with the advent of technology, researchers may be able to see further with different telescopes.
