Poyasnenie:
Oni vyglyadyat, kak sovremennye mehanicheskie dinozavry, no na samom dele eto –
ogromnye povorachivayushiesya glaza, nablyudayushie za nebom.
Stereoskopicheskaya sistema vysokoi energii
(High Energy Stereoscopic System – H.E.S.S.)
sostoit iz chetyreh teleskopov s 12-metrovymi zerkalami,
okruzhayushimi
bol'shoi teleskop
s zerkalom diametrom v 28 metrov.
Oni prednaznacheny dlya registracii strannyh vspyshek golubogo sveta –
cherenkovskogo izlucheniya,
kotoroe voznikaet, kogda
zaryazhennye chasticy
dvizhutsya nemnogo bystree
skorosti sveta v vozduhe.
Vspyshki proishodyat, kogda
gamma-luchi
iz dalekih istochnikov stalkivayutsya s molekulami v zemnoi atmosfere, vyzyvaya
livni iz zaryazhennyh chastic.
H.E.S.S.
mozhet registrirovat' fotony, puteshestvuyushie po Vselennoi, energiya kotoryh dostigaet
teraelektronvol't.
H.E.S.S. rabotaet v
Namibii
s 2003 goda, on ispol'zovalsya dlya poiska
temnoi materii
i otkryl bolee
50 istochnikov
vysokoenergichnogo izlucheniya, vklyuchaya
ostatki sverhnovyh i
centry galaktik,
v kotoryh nahodyatsya
sverhmassivnye chernye dyry.
Eto video
bylo snyato v sentyabre proshlogo goda.
Teleskopy H.E.S.S. povorachivayutsya i nablyudayut nashu
Galaktiku Mlechnyi Put' i
Magellanovy Oblaka,
a mimo sluchaino proletaet obrashayushiisya vokrug Zemli sputnik.
