Image 2:
Michelson Doppler Imager (MDI) onboard the Solar and Heliospheric Observatory (SOHO) spacecrafttook this image of a stormy area on the Sun in which sunspots appear. Solar astronomers have long known that the intense magnetic field below a sunspot strangles the normal up-flow of energy from the hot solar interior, leaving the spot cooler and therefore darker than its surroundings.
