Rare US solar eclipse to help unlock sun's secrets
A total solar eclipse Monday will travel across the U.S. and provide scientists with the best opportunity in modern history to explore some of the secrets about the sun’s corona.
The coast-to-coast path along a 70-mile (113-kilometer) wide strip of land will help astronomers to study the sun with the help of new technology, on the ground and in space, that was not available during prior eclipses.

“One of the things that is so remarkable about this eclipse is that it crosses 26 miles of continuous landmass which means you can have observers spaced out all along the path from Oregon to North Carolina,” said Dr. Rick Feinberg, spokesman for the American Astronomical Society.

“As the eclipse moves across the country and you hand off from one team to the next, we basically can observe the sun’s corona continuously for about an hour and half, which has never happened before,” he said.

The last American total solar eclipse was 38 years ago, and the last one to cross the entire continental U.S. was in 1918, making the eclipse Monday --observed for the longest in Carbondale, Illinois, for less than three minutes -- the opportunity of a century.
