Poyasnenie: Kak vyglyadelo by nebo, esli posmotret' na nego v gamma-luchah, energiya kotoryh v 40 millionov raz prevyshaet energiyu vidimogo sveta? Eto izobrazhenie yavlyaetsya model'yu vozmozhnogo raspredeleniya intensivnosti gamma-izlucheniya po nebu, kak ego veroyatno uvidit Gamma-ray Large Area Space Telescope (GLAST) po rezul'tatam pervogo goda svoei raboty na orbite. V oblasti razmerom 80h80 gradusov v napravlenii pryamo protivopolozhnom centru Galaktiki ischezli znakomye zvezdy. Vmesto nih poyavilis' pul'sary Geminga i Krab prichudlivye bystro vrashayushiesya zvezdnye trupy, izvestnye pod nazvaniem neitronnyh zvezd, kotorye yavlyayutsya naibolee yarkimi istochnikami gamma-izlucheniya. Eti i nekotorye drugie istochniki, sredi kotoryh chudovishnye aktivnye galaktiki i nekotorye ob'ekty poka eshe neizvestvnoi prirody, byli obnaruzheny ustanovkoi Energetic Gamma-Ray Experiment Telescope (EGRET), na bortu orbital'noi gamma-observatorii Komptona. Odnako, bol'shinstvo smodelirovannyh istochnikov novye. Oni otrazhayut ekstrapolyaciyu sushestvuyushih idei i preduprezhdayut otkrytiya, ozhidaemye ot uluchshennoi sistemy gamma-zreniya observatorii GLAST. Shirokaya slabo svetyashayasya central'naya polosa voznikaet pri stolknovenii vysokoenergichnyh chastic kosmicheskih luchei s mezhzvezdnym gazom vo vneshnih spiral'nyh rukavah Mlechnogo Puti, a nizhe vidno diffuznoe svechenie izvestnyh molekulyarnyh oblakov v Edinoroge, Orione, Voznichem i Tel'ce. Proekt GLAST prednaznachen dlya issledovaniya predel'nyh sostoyanii veshestva v dal'nem kosmose. On sozdaetsya NASA s uchastiem mezhdunarodnyh partnerov i zaplanirovan k zapusku v 2005 godu.
