NASA is teasing a monumental discovery that could change everything we know about life in the universe. From JWST’s hunt for atmospheric biosignatures to Perseverance’s Mars samples, this video explores how scientists search for life across light-years and what a confirmed find would mean for science, technology, and humanity. Are we alone—or on the edge of a paradigm shift?What you’ll learn:How JWST analyzes exoplanet atmospheres for biosignatures like oxygen and methane [science.nasa.gov]��.Why Mars sample return and Perseverance’s delta exploration matter for finding ancient microbes [science.nasa.gov]�.The ethical, technological, and societal implications if extraterrestrial life is confirmed.
