Living near a star is risky business, and positioning a spacecraft near the Sun is a very good way to observe rapidly changing solar activity and deliver early warning of possibly harmful space weather. ESA is now looking at doing just that.
On most days, our normally calm Sun goes about its business, delivering a steady and predictable amount of heat and light that keeps planet Earth and its humans ticking.
But just as the Sun drives weather on Earth, solar activity is responsible for disturbances in our space environment, dubbed ‘space weather’.
Besides emitting a continuous stream of electrically charged atomic particles, the Sun periodically sneezes out billions of tonnes of material threaded with magnetic fields in colossal-scale ‘coronal mass ejections’.Continue reading in ESA's webpage
