Coronal mass ejections (CMEs) are massive bursts of solar wind and magnetic fields ejected from the Sun's corona, the outermost layer of the Sun's atmosphere. These events can release a large amount of energy and plasma into space, causing disturbances in the Earth's magnetosphere and potentially affecting satellite communications, power grids, and other technological systems on or near our planet. CMEs are often associated with solar flares, which are intense bursts of radiation and energy from the Sun's surface. The occurrence of CMEs is closely related to the solar activity cycle, which follows an 11-year cycle of increasing and decreasing solar activity. Researchers study CMEs to better understand their impact on space weather and how they can potentially affect Earth and other planets in our solar system. By monitoring and predicting CME events, scientists can better prepare for potential disruptions caused by these events and mitigate their impact on technology and infrastructure.
