Here comes the sun

Quickly before my student shows up & then I begin tootling in preparation for the concert tonight, I wanted to forward this link to the Solar Dynamics Observatory that I heard about on a recent nova program. Great source for desktop pictures & fascinating work they're doing studying the sun - thousands of years for photons to make their wan from its center to the surface & then begin their journey out into space? Incredible. OK - gotta go!

    John, I saw that Nova program--it was so amazing that I looked for and found a repeat airing of it so that I could watch again. I loved the explanation of how the magnetic "lines" cause the plasma to jump out from the sun's surface. Wishing you pleasant photons today ;-) Elizabeth
