Space Weather
Space weather refers to conditions and events that occur in space, caused by the behavior of the Sun's magnetic field. These events can impact satellites, communications, power grids, and navigation, among other things down on Earth. Forecasting space weather is crucial to handling these various factors, while also enabling safe space travel.
