- Solar activity is driven by the solar magnetic field1. The Sun goes through regular cycles of activity lasting approximately 11 years2. During the most active part of the cycle, known as solar maximum, the Sun can unleash immense explosions of light, energy, and solar radiation2. Scientists track solar cycle progress using sunspots, which are associated with solar activity3.Learn more:✕This summary was generated using AI based on multiple online sources.

Solar flares, coronal mass ejections, high-speed solar wind, and solar energetic particles are all forms of solar activity. All solar activity is driven by the solar magnetic field.www.nasa.gov/image-article/what-solar-activity/The Sun goes through regular cycles of activity lasting approximately 11 years. During the most active part of the cycle, known as solar maximum, the Sun can unleash immense explosions of light, energy, and solar radiation, all of which create conditions known as space weather.www.nasa.gov/news-release/nasa-noaa-to-provid…Scientists use sunspots to track solar cycle progress; the dark spots are associated with solar activity, often as the origins for giant explosions - such as solar flares or coronal mass ejections - which can spew light, energy, and solar material out into space.svs.gsfc.nasa.gov/14683
