400-YEAR OLD SUNSPOTS: Today is the 442nd birthday of Galileo Galilei,
a figure of importance in the history of space weather. Contrary to popular belief, Galileo didn't discover sunspots, but he was one of the first to observe them using a telescope and he discovered many of their basic properties. Visit http://spaceweather.com to learn more about Galileo's pioneering work and to see actual drawings of sunspots he made more than four centuries ago. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
