For centuries, the earth has looked at the sky and wondered about life among the stars. But since humans hunted small green humans, aliens may have looked back at us.
In new research, astronomers have drawn up a list of nearby stellar systems where any researchers orbiting the planets would be well placed to find life on Earth.
Scientists have identified 1,715 star systems in our cosmic environment, where alien observers may have discovered them by “transporting” the earth across the face of the sun over the past 5,000 years.
Among those who are in the right position to observe Earth’s orbit, 46 star systems are close enough to intercept their planets’ clear signal of human existence – radio and television broadcasts that began about 100 years ago.
Researchers estimate that 29 habitable planets have witnessed the movement of the Earth, and listen to human radio and television broadcasts, allowing any viewer to guess an intelligence. An important aspect is whether broadcasts force an advanced civilization to build contacts.
Lisa Caldenecker, professor of astronomy at Cornell University in New York and director of the Carl Sagan Institute, says: “One way to find the planets is to block a portion of the light from their host star. “We asked, ‘If anyone else sees who we are as foreigners?’ There is this little silver in the sky, where other star systems are a cosmic front seat to find Earth as a planet. ”
Earth astronomers have discovered thousands of planets beyond the solar system. About 70% are seen when alien worlds go in front of their host stars and block some of the light that reaches scientists’ telescopes. Future labs like NASA James Webb Space Telescope Launched this year, it will look for signs of life in “exoplanets” by analyzing the composition of their atmospheres.
Chaldean and Dr. Jackie Baherty, astronomers at the American Museum of Nature, turned to Europe to find out which stellar systems were nearby to observe Earth’s transport. Location List of agency’s Kia star positions and movements. From this they have identified 2,034 star systems within 100 barsecs (326 light years) that can detect Earth transport at any time from 5,000 years ago to 5,000 years into the future.
A star in Virgo, a red dwarf called Rose 128, is about 11 light-years away – close enough to receive Earth’s broadcasts – and has a planet twice the size of Earth. Any fitted life on the planet could have traced the Earth’s transportation over 2,000 years, but lost its vantage point 900 years ago. If there is any brilliant life on the two known planets in orbit DeGordon’s star, 12.5 light-years away, would be a prime position to see Earth transport in 29 years.
45 light-years away, another star, called Tropist-1, is close enough to hear human broadcasts. The star carries at least seven planets, four of which are in a temperate, habitable zone, but scientists write that they will not be able to see Earth’s orbit for another 1,642 years. Natural.
The findings come as the US government prepares to release The most anticipated report on unidentified flying objects (UFOs). The Pentagon’s unidentified aeronautical task force report, which was set up to gain insight into the nature and origin of the unknown aircraft, did not expect to reveal or dismiss evidence of alien activity.
Professor Beth Pillar at the University of Edinburgh AstronomyHe said the work could change how scientists approach the search engine for extraterrestrial life, which is not involved in natural research. “What amazes me is that some stars within 100 barsecs could have seen a crossing earth,” he said.
“The mode of transportation requires a very precise alignment between the planet, its star, and the sun to detect a particular planet, so this result is not surprising. I am now curious as to which part of the Kia list of nearby stars has the perfect location to detect the Earth by other exoplanet detection methods such as radial velocity or direct imaging! ”
