Scientists search Milky Way for life's chemical signs

Scientists are using advanced telescopes and lab experiments to detect biosignatures, chemicals indicating life, in exoplanet atmospheres. The James Webb Space Telescope analyzes starlight filtered through exoplanet atmospheres, while laboratory work helps identify specific molecules like sulfur dioxide. Future telescopes will enhance this search, focusing on rocky planets in habitable zones, with computational methods improving the identification of unknown spectral features.
