The March 29, 2006, eclipse lasted more than four minutes at the center of its path Most total solar eclipses last two minutes or less Total solar eclipses are of special interest to astronomers because they are the only time the sun's corona can be seen from the Earth's surface Observers can detect and measure properties of the sun's outer atmosphere, such as temperature, density and chemical composition, when the light of the disk is blocked by the moon

The next total solar eclipse will occur Aug 1, 2008 It will last about two minutes and can be seen in northern Canada, Greenland, Siberia, Mongolia and northern China The next total solar eclipse visible from the United States is not until Aug 21, 2017
