Astronomers have discovered thousands of planets using the transit technique, watching how distant stars dim as a planet passes in between us and the star. A small group of stars is lined up so alien astronomers can discover Earth using the same transit technique. In a new paper, researchers suggest that the upcoming Nancy Grace Roman Telescope should scan this Earth's transiting zone for habitable planets. If there are other advanced civilizations there, they should know we're here and would be...
