Curious layman Posted October 23, 2020 Posted October 23, 2020 Quote There are about 1,000 star systems where aliens, if they existed, could be watching us from afar, new research suggests. Those 1,004 star systems are in a direct line of sight to our planet, and close enough to us that they could not only detect planet Earth, but also chemical traces of Earthly life. https://www.livescience.com/aliens-spot-earth-exoplanets.html 1
MigL Posted October 24, 2020 Posted October 24, 2020 The Sun is a magnitude 5.8 star, barely visible from 50 LY distance. However, about 100 years ago, we started broadcasting information embedded in EM carrier waves out into the universe. Any advanced civilization residing on one of the 133 star systems within 50 LY, would have detected us 50 years ago, and their armada, travelling here at light speed should be passing the outer gas giants as we speak. Yeah, I'm joking ( maybe ). 1
Jon2071 Posted October 26, 2020 Posted October 26, 2020 I just recently read the article that explored this topic. As our planet rotates around the sun is briefly makes the sun just a bit dimmer so if anyone is watching they will realize a our planet exists.
