A super-Earth in a distant star system may explain what Mars, Venus, and Earth were like billions of years ago -- incredibly hot and covered in magma oceans. Those oceans may have supplied the planets with early atmospheres full of gases needed for life. While Venus's atmosphere became thick and heavy and Mars couldn't hold on to its atmosphere, Earth became a truly habitable world where life thrives. What can 55 Cancri e, over 40 light years away, teach us about our early solar system? Planetary scientist Beth Johnson asks Renyu Hu (NASA JPL) about his recent paper that uses JWST to examine the distant world's atmosphere. (Recorded 22 August 2024.)
