Ooh, bubbles! 🫧 But what can they tell us about the possibility of life beyond Earth? NASA scientists are studying how carbon moves through extreme environments on Earth to better understand how it might cycle through the hidden oceans of icy moons like Enceladus, one of Saturn’s moons. These processes could help scientists understand whether the ingredients needed for life might be available beneath the ice. What can Earth's environments teach us about ocean worlds? 🌊 Watch the full expedition below to learn more.
