For many people around the world, it is difficult to imagine with the large number of stars in the universe and the large number of planets orbiting these stars that we are all alone Until ‘Now, scientists have discovered more than 4,000 planets orbiting distant stars, known as exoplanets.Cornell University astronomers recently published a study in which they questioned whether among all these exoplanets that we observe from Earth, could any of them look back?
Astronomer Lisa Kaltenegger says the team asked who could also spot us The researchers wanted to know which of the exoplanets could have determined that Earth had life from their perspective The astronomer worked with Joshua Pepper, associate professor of physics at Lehigh University, to identify more than a thousand stars similar to our sun that may have Earth-like planets orbiting at a distance that can support liquid water
Researchers have made it clear that planets of this type have yet to be discovered around stars Astronomers say it takes a specific location to be able to see the Earth move in front of the sun As our planet transits through the sun, our star briefly fades from the perspective of the distant exoplanet
Gradation during transit would allow the distant planet to know that a planet revolves around the star and is at the correct distance to have liquid water In their study, the astronomers identified the thousand stars nearest ones within 300 light years that could have spotted us Anyone looking from these exoplanets could see signs of a biosphere in our planet’s atmosphere
As far as these 1000 distant stars are from Earth, we can see some of them in the night sky with the naked eye.It’s interesting how many exoplanets might know that life is on our planet
