In this video from NOVA's Sun Lab, explore the relationship between solar activity and space weather. Images and animations show how the Sun releases energy and matter that travel through the solar system. There are two main kinds of solar storms: solar flares and coronal mass ejections. Solar storms are related to fluctuations in the Sun's magnetic fields; sunspots are indicative of solar activity. Only a small percentage of solar particles affect Earth, but solar storms have the potential to cause serious damage.
