Space weather

Space weather refers to the dynamic conditions in the space environment surrounding Earth, shaped primarily by activity from the Sun. Unlike terrestrial weather, space weather involves charged particles, magnetic fields, and X-rays that stream outward from our star, particularly during solar storms and coronal mass ejections.

These energetic events can disrupt GPS and GLONASS navigation systems, damage satellites, interfere with power grids, and pose radiation risks to astronauts and airline crews at high altitudes. The solar wind—a constant stream of particles—creates the Magnetosphere, Earth's protective magnetic bubble that shields us from most cosmic threats.

Space weather follows patterns linked to the Solar cycle, an approximately 11-year rhythm of solar activity. Scientists monitor it using satellites and ground-based observatories to predict dangerous eruptions hours or days in advance. Understanding space weather is increasingly vital as our technological civilization grows more dependent on satellites and electrical infrastructure.

The field combines insights from plasma physics, Solar observation, and Forecasting, making it essential for protecting modern society while advancing our knowledge of Nucleosynthesis and stellar behavior.
