GREENBELT, Md., June 11 (UPI) -- A NASA space telescope detected the highest-energy light ever measured in an eruption on the sun during a powerful solar blast, the space agency has reported.
The powerful solar flare, observed March 7 by the Fermi Gamma-ray Space Telescope, produced such an outpouring of gamma rays -- a form of light with even greater energy than X-rays -- that the sun briefly became the brightest object in the gamma-ray sky, NASA said Monday.
