Poyasnenie: Dlya orbital'nogo gamma-teleskopa Zemlya na samom dele yavlyaetsya samym yarkim istochnikom gamma-izlucheniya — samoi vysokoenergichnoi formy sveta. Gamma-luchi, prihodyashie s Zemli, rozhdayutsya, kogda vysokoenergichnye chasticy kosmicheskih luchei stalkivayutsya s atmosferoi. I hotya takoe vzaimodeistvie prepyatstvuet popadaniyu vrednoi radiacii na poverhnost' Zemli, zemnoe gamma-izluchenie dominiruet na etom zamechatel'nom snimke Zemli i neba, poluchennom s pomosh'yu teleskopa LAT (Large Area Telescope — Teleskop Bol'shoi Ploshadi), ustanovlennogo na orbital'noi gamma-observatorii Fermi. Izobrazhenie bylo postroeno tol'ko po tem nablyudeniyam, kogda Mlechnyi Put' prohodil vblizi zenita, to est' tochno nad sputnikom Fermi. Na kartinke zenit nahoditsya v centre. Zemlya i tochki vblizi nadira, nahodyashiesya pryamo pod sputnikom, nahodyatsya u kraev izobrazheniya, obrazuya proekciyu Zemli i vsego neba s tochki zreniya Fermi. Gamma-izluchenie nizkoi intensivnosti pokazano sinim cvetom, a bolee yarkie uchastki izobrazheny zheltymi ottenkami v logarifmicheskoi shkale. Krai izobrazheniya zapolnilo zheltoe kol'co yarkogo gamma-izlucheniya, kotoroe pokazyvaet raspolozhenie limba nashei skromnoi planety. Otnositel'no slaboe gamma-izluchenie ot istochnikov v Mlechnom Puti narisovalo polosu, rastyanuvshuyusya po diagonali. Observatoriya Fermi byla zapushena v kosmos 11 iyunya 2008 goda chtoby issledovat' Vselennuyu v vysokih energiyah, i na etoi nedele ona prazdnuet 2000-yi den' na nizkoi okolozemnoi orbite.
