Fermi Sees Gamma Rays from Far Side Solar Flares

An international science team says NASA’s Fermi Gamma-ray Space Telescope has observed high-energy light from solar eruptions located on the far side of the sun, which should block direct light from these events. This apparent paradox is providing solar scientists with a unique tool for exploring how charged particles are accelerated to nearly the speed of light and move across the sun during solar flares. Fermi has seen gamma rays from the Earth-facing side of the sun, but the emission is produced by str
