A new study suggests that some of those planets and any extraterrestrial life that lives on them can see us too.
These star systems have a "direct line of sight to observe Earth’s biological qualities from far, far away," according to a statement accompanying the research.
300 MILLION HABITABLE PLANETS EXIST, NASA SAYS.The findings, while thought-provoking, are limited by the amount of time each of the star systems can observe Earth, the researchers noted.It's also possible the life on these planets could exist for billions of years, given the properties that they are believed to possess, a sign they need additional studyThese planets have been observed due to transit observations, or when an object crosses in front of a star, dimming the star, thus allowing astronomers to see it. This type of observation will be expanded when NASA launches its James Webb Space Telescope in October 2021
