Spacetime With Stuart Gary

In this episode of SpaceTime, we delve into fascinating connections between Earth's atmospheric conditions and its magnetic field, alongside intriguing insights into Mercury and the mysteries of the Sun's corona.Link Between Earth's Oxygen and Magnetic FieldA groundbreaking study published in Science Advances reveals a correlation between the fluctuations of Earth's magnetic field and atmospheric oxygen levels over the last 540 million years. Researchers suggest that processes within the Earth might influence habitability on the surface, highlighting the magnetic field's role in protecting our atmosphere from cosmic rays and solar wind. This correlation raises questions about the underlying processes linking these two critical elements for life on Earth.Unraveling Mercury's SecretsNew findings indicate that Mercury's crust and internal structure are unlike any other planet in our solar system. Laboratory simulations are aiding the European-Japanese BepiColombo mission, set to orbit Mercury in November 2026. R
