"Testing Earth as a Model for Alien Habitability Detection"

Scientists have simulated the performance of the proposed space telescope, LIFE, by focusing it on Earth as if it were a distant exoplanet to detect potential signs of life. The telescope, overseen by ETH Zürich, aims to study 30 to 50 Earth-sized exoplanets within 65 light years of our solar system for biosignatures in their atmospheres. The study's findings, published in The Astronomical Journal, suggest that the telescope's ambitions are viable, offering hope for answering the question of whether life exists beyond Earth.
