Description: As humanity ramps up its search for alien life, we should keep in mind that extraterrestrials might be hunting for us as well. To spot Earth, alien astronomers on these exoplanets would need to use the same techniques we do to catalogue a distant object: watching as Earth passes in front of the Sun to figure out the makeup of our planet's atmosphere, known as a transit observation. Astronomers are working hard to catalogue all of the exoplanets visible from Earth, but now two researchers have turned the idea around, to look at which exoplanets are getting a good view of Earth in return. Earth is visible from 1004 Alien distant Earth-like exoplanets It turns out there are 1,004 (and counting) main sequence stars, similar to the Sun, with orbiting Earth-like planets that probably have an opportunity to detect chemical traces of life on our own planet. If there's anyone up there, they can see us. Data from NASA's Transiting Exoplanet Survey Satellite (TESS) star catalogue and the Gaia star map was used to make the calculations, and over time the star systems that can view Earth will change. When the NASA James Webb Space Telescope finally launches, studying space in the infrared spectrum, it will give us even more information about the composition of exoplanets and the story of the early universe. #matrixdisclosure #exoplanets #universe
