Poyasnenie:
Zabud'te o
rentgenovskom zrenii
i predstav'te, chto vy mozhete videt'
gamma-luchi!
Eta karta vsego neba
pokazyvaet, kak vyglyadit Vselennaya dlya
Kosmicheskogo gamma-teleskopa NASA "Fermi".
"Fermi" registriruet svet s energiei, primerno v milliard raz bol'shei, chem
vidit
chelovecheskii glaz, a eta
karta
postroena na osnovanii 12-letnih nablyudenii.
Cveta pokazyvayut yarkost'
istochnikov gamma-luchei,
bolee yarkie okrasheny v svetlye tona.
Yarkaya polosa v seredine kartinki – central'naya ploskost' nashei
Galaktiki Mlechnyi Put'.
Bol'shinstvo krasnyh i zheltyh tochek, rasseyannyh vyshe i nizhe Mlechnogo Puti –
ochen' dalekie galaktiki,
a bol'shaya chast' tochek vnutri
ploskosti
– blizkie
pul'sary.
Sinii
fon na kartinke –
diffuznoe gamma-izluchenie
ot dalekih istochnikov, kotorye nevozmozhno zaregistrirovat' individual'no.
Nekotorye gamma-istochniki ostayutsya
ne identificirovannymi
i yavlyayutsya ob'ektami issledovanii, odnako poka
nikto ne znaet, chto oni soboi predstavlyayut.
