NASA's James Webb Space Telescope has captured images of Jupiter's moon, Europa, revealing an abundance of carbon dioxide on its frigid surface. This finding suggests the possibility of life beneath the moon's icy crust. While the presence of carbon dioxide is a vital building block for life, further investigation is needed to determine if the moon is habitable. The discovery of carbon dioxide in Europa's Taro Regio region, along with previous findings of ocean-derived salts, provides valuable clues about the moon's hidden biosphere.
