Severnoe siyanie
poyavlyaetsya, kogda bystro dvizhushiesya chasticy, ispushennye Solncem, vletayut v
magnitosferu Zemli.
Zaryazhennye chasticy dvizhutsya po spirali vdol' silovyh linii
magnitnogo polya Zemli
i stalkivayutsya s atomami i molekulami v verhnih sloyah
zemnoi atmosfery.
Atom
kisloroda
posle vozbuzhdeniya takim stolknoveniem izluchaet zelenyi cvet, chasto vstrechayushiisya v
severnyh siyaniyah.
Nizhnyaya granica
severnogo siyaniya
obychno nahoditsya na vysote bolee 100 kilometrov, v to vremya kak bol'shinstvo oblakov
mogut sushestvovat' tol'ko nizhe 10 kilometrov.
Otnositel'naya vysota oblakov i
severnogo siyaniya
horosho vidna na
etom snimke, sdelannom v
Dirholei v
Islandii.
Reshitel'nomu astrofotografu prishlos' vyderzhat' sil'nyi
veter, pytayas' zapechatlet' severnoe siyanie nad
zhivopisnym mayakom,
k tomu zhe vnachale nebo bylo zatyanuto tuchami.
