The sun has decided to participate in preparations for Earth Day, which is less than a month away. Use your dedication to organic living and the environment, coupled with the wonders of modern technology, to teach your children more about our planet.

NASA and San Francisco’s Exploratorium are teaming up to provide webcast, podcast and broadcast of tomorrow’s total solar eclipse. The coverage is part of this year’s Sun-Earth Day theme, “Eclipse: In a Different Light,” which shows how solar eclipses have inspired people to observe and understand our universe.

This eclipse is special because the total phase lasts more than 4 minutes at the center of the path. (Most last only a minute or two.) The next total solar eclipse is Aug. 1, 2008, and it will be seen in northern Canada, Greenland, Siberia, Mongolia and northern China. The next total solar eclipse visible from the United States won’t happen until Aug. 21, 2017.

If you’re a teacher, share the event with your students. NASA’s Public Service Channel (#101) and Education Channel (#102) will carry the webcast. NASA’s Media Channel (#103) will carry a live feed of the eclipse.
