The first total solar eclipse to sweep across the entire US since 1918 is happening on August 21, 2017. The eclipse center line will enter the US crossing Oregon between Lincoln City and Newport and will exit three hours later in South Carolina between Georgetown and Charleston. If you've never seen a total solar eclipse, here's your chance! NASA is here to help you prepare for this wondrous natural spectacle.
A major solar 'superstorm' such as the one in 1859 could cost $30 billion a day to the US electrical power grid, and up to $70 billion to the satellite industry.
