American scientists have identified 1,715 star systems in the space region where “alien observers” may have discovered Earth in the past 5,000 years.

A scientific study shows that, while humanity is still trying every day to advance further in conquering the universe, somewhere out there, aliens may also be silently observing Earth. .

American scientists have identified 1,715 star systems in our region of the universe, where “alien observers” may have discovered Earth in the past 5,000 years.

In particular, 46 of these star systems are at a distance enough to block clear signals proving human existence, specifically the wave signals of radio and television programs that began about 100 years ago. year.

Researchers estimate that 29 potentially habitable planets are well positioned to witness Earth’s movement around the Sun and “eavesdrop” on human radio and television transmissions. . This “eavesdropping” can help aliens determine whether to “reveal” or continue to “hide”. This is also a debate point that attracts the attention of current scientists.

According to professor of astronomy and director of the Carl Sagan Institute at Cornell University in New York – Lisa Kaltenegger and astrophysicist Jackie Faherty at the American Museum of Natural History shared, the team of scientists discovered thousands of planets outside the solar system have been discovered over many years of research. About 70% of planets are discovered when they pass in front of their host stars, blocking some of the light reaching scientists’ telescopes.

A star with a high possibility of being inhabited by aliens and observing us is: Ross 128, a red dwarf star in the constellation Virgo, about 11 light years away from us; Trappist-1, 45 light years away.

This discovery was made as the US government prepared to release a highly anticipated report on unidentified flying objects (UFOs) and was assessed by the scientific community as “could change the way scientists approaching the universe and searching for extraterrestrial life.”
