... 2013 December 6 . Gamma-Ray Earth and Sky . Image Credit: International Fermi Large Area Telescope Collaboration , NASA , DOE . Explanation: For an Earth-orbiting gamma-ray telescope, Earth is actually the brightest source of gamma-rays , the most energetic form of light. ... While that interaction blocks harmful radiation from reaching the surface, those gamma-rays dominate in this remarkable Earth and sky view from the orbiting Fermi Gamma-ray Space Telescope's Large Area Telescope. ...

... Solar flare activity is produced by the processes of accumulation and release of energy in an active region. ... In the framework of study of solar active regions, producing powerful flares the researchers from the RATAN-600 radio telescope have detected sources with features in the form of a sharp drop in the intensity of polarized radiation in various parts of the recorded frequency range (2-16GHz), sometimes changing the sign of polarization. ...
