3I/ATLAS carbon could hint at life beyond Earth: Avi Loeb | Elizabeth Vargas Reports

NASA's discovery that interstellar comet 3I/ATLAS is approximately 10-12 billion years old—nearly three times older than our solar system—and contains carbon-rich compounds and 30 times more heavy water than solar system comets suggests that the organic chemistry necessary for carbon-based life existed in the universe billions of years before Earth formed. The comet's unusual trajectory, high speed, and deuterium abundance (1000 times cosmic average) indicate it originated from an ancient parent star, while its methane outgassing near the Sun may represent a biosignature, raising questions about whether life-like processes exist in this interstellar object.
