NASA - NASA'S Fermi Detects The Highest-Energy Light From A Solar Flare

NASA - NASA'S Fermi Detects The Highest-Energy Light From A Solar Flare: WASHINGTON -- During a powerful solar blast on March 7, NASA's Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun. The discovery heralds Fermi's new role as a solar observatory, a powerful new tool for understanding solar outbursts during the sun's maximum period of activity.
