sunspots  

Définition

  • First viewed through a telescope by Galileo Galilei in 1610, sunspots are dark, active regions on the surface of the sun (the photosphere) that have a stronger magnetic field and cooler temperatures than the surrounding areas. The dynamo process (flow of solar plasma) within the exterior layers of the sun creates a magnetic field where con-vective motions transfer heat from the interior of the sun to its surface. [Source: Encyclopedia of Global Warming & Climate Change; Sunspots]
