Description: Is Earth Being Watched? Can Alien Civilizations see Earth? Past, present and future stars that can see Earth as a transiting exoplanet is a new paper by Dr. Jackie Faherty and Dr. Lisa Kalteneggar. It reports that "In the search for life in the cosmos, transiting exoplanets are currently our best targets. With thousands already detected, our search is entering a new era of discovery with upcoming large telescopes that will look for signs of ‘life’ in the atmospheres of transiting worlds. Previous work has explored the zone from which Earth would be visible while transiting the Sun1–4. However, these studies considered only the current position of stars, and did not include their changing vantage point over time. Here we report that 1,715 stars within 100 parsecs from the Sun are in the right position to have spotted life on a transiting Earth since early human civilization."
