SOLAR CYCLE 25

What is a solar cycle?

• Since the Sun’s surface is a very active space, electrically charged gases on its surface generate areas of powerful magnetic forces, which are called magnetic fields.
  
  
• Since the gases on the Sun’s surface are constantly moving, these magnetic fields can get stretched, twisted and tangled creating motion on the surface, which is referred to as solar activity.
  
  
• Solar activity varied with the stages of the solar cycle, which lasts on average for a period of 11 years. Solar cycles have implications for life and technology on Earth as well as astronauts in space.
