Where did Earth’s water come from?
Sara Russell, a planetary scientist at the Natural History Museum, and Richard Greenwood, a meteorite researcher at The Open University, dive into the origins of Earth's water. They discuss how water likely didn't exist when the planet formed from molten rock and explore theories suggesting asteroids, like Bennu, might have contributed to our water supply. Additionally, they examine oxygen isotopes linking Earth and the Moon, shedding light on cosmic impacts and the timeline of water's arrival on our planet.
