06 - POLARNA SVETLOST NA DRUGIM PLANETAMA

Post by Admin on Sun Jun 07, 2015 7:24 pm


Aurora je opažena i na Jupiteru i Saturnu, planetima čija su magnetska polja mnogo snažnija od Zemljinog. Pokreće ih, kao i na Zemlji, Sunčev vjetar. Jupiterovi mjeseci, posebno Io, također uzrokuju snažne aurore koje se javljaju zbog električnih struja duž silnica magnetskog polja između rotirajućeg planeta i mjeseca koji kruži oko njega (dinamo efekat).


Io (koji ima aktivni vulkanizam i ionosferu) je posebno snažan izvor aurore; njegove struje emituju i radiotalase, otkrivene 1955. godine. Nedavno je polarna svetlost otkrivena i na Marsu. Zbog nedostatka jakog magnetskog polja, ranije se vjerovalo kako je to nemoguće.

Umetnicka vizualizacija aurore na braon patuljku LSR J1835+3259.
On je od nas udaljen 18 svetlosnih godina i jacina aurore je
10.000 puta veca od one na Jupiteru.
