Spacetime With Stuart Gary

In this episode of SpaceTime, we unveil groundbreaking evidence that challenges previously held theories about the origins of Earth's water. Recent findings published in the journal Icarus indicate that rather than being delivered by asteroids and comets, Earth's water may have formed alongside the planet itself. The study utilizes a unique meteorite known as the enstatite chondrite to reveal a rich source of hydrogen essential for water formation, reshaping our understanding of how life-sustaining conditions developed on Earth.The Enigmatic Magnetic Field of MarsNext, we delve into the curious case of Mars's magnetic field, which has puzzled scientists for decades. A new study suggests that the strange magnetic signatures observed on the Red Planet could be attributed to a partially molten core predominantly covering the southern hemisphere. This research provides fresh insights into Mars's geological history and the implications for its atmospheric evolution, as the planet transitioned from a warm, wet envi
