Poyasnenie:
Kak mozhet gaz plavat' nad Solncem?
Zaputannye
magnitnye
polya, izgibayushiesya nad
poverhnost'yu Solnca,
zahvatyvayut ionizovannyi gaz, sobiraya ego v ogromnye struktury, imeyushie formu petel'.
Eti velichestvennye plazmennye dugi
vidny kak protuberancy nad limbom Solnca.
V 1999 godu eto effektnoe i podrobnoe
izobrazhenie
v linii, izluchaemoi ionizovannym geliem,
bylo polucheno teleskopom, dayushim izobrazheniya v dal'nem ul'trafiolete na bortu
kosmicheskoi observatorii SOHO.
Na nem vidno, kak goryachaya plazma ustremlyaetsya v kosmicheskoe prostranstvo, kogda
ognennyi protuberanec osvobozhdaetsya ot
uderzhivayushego magnitnogo polya
na vysote sto tysyach kilometrov nad Solncem.
Eti privodyashie v trepet yavleniya
neobhodimo nablyudat',
tak kak oni okazyvayut vliyanie na sistemy svyazi i energosnabzheniya na rasstoyanii
bolee
sta millionov kilometrov – na
planete Zemlya.
V konce 2020 goda nashe Solnce proshlo
minimum
11-letnego cikla
i seichas
aktivnost' na poverhnosti vozrastaet.
