Helioseismologists, using an instrument onboard the Solar and Heliospheric Observatory (SOHO) satellite, have found that there is something new under the Sun, or at least beneath the Sun's surface.

Two teams of scientists working with SOHO's Michelson Doppler Imager (MDI) presented their findings on the formation and growth of active regions of solar activity and on spinning sunspots at the AGU Fall Meeting in December in San Francisco, California. The findings help to better understand solar activity that can result in solar flares and coronal mass ejections that disrupt communication and energy systems on Earth.
