From the explanation

“Our Milky Way galaxy appears to be surrounded by a halo of gamma rays . Gamma rays are the most energetic form of electromagnetic radiation , with more than a hundred thousand times the energy of visible light, but known gamma-ray sources don’t account for the diffuse distribution of this high-energy glow.”

— APOD editors, November 5, 1997
