NASA scientists believe sunspots form when the sun's magnetic pressure increases, whereas the surrounding atmospheric temperature decreases, due to the magnetic field suppressing hot gases. Strong magnetic points prevent... More »

Sunspots do not have any effect on the Earth in any significant way. If the sun was covered in sunspots, it could result in less light reaching Earth, but not enough to have any negative effect or even be noticed. Howeve... More »

The Stanford Solar Center states that sunspots form when the sun's magnetic field protrudes through its surface. The sun's magnetic field is composed of tubes that affect the sun’s surface temperature at the point of pro... More »

The effects of the sun's internal magnetic fields entering and re-entering the surface of the sun result in sunspots. They typically occur in pairs with magnetic fields pointing in opposite directions. More »

The sun is a gigantic ball of hot gases. It is comprised of approximately 72 percent hydrogen, 26 percent helium and minute amounts of other elements, such as carbon, oxygen, neon, iron, nitrogen, magnesium and silicon. More »

Solar winds are caused by variance in the magnetic field of the sun. Certain lines in the magnetic field allow particles to travel outward easily and to pick up speed as they move. More »
