See on \u00f6\u00f6taevas lainetav kaunis valguse kardin, mis pakub neile, kellel on olnud \u00f5nn seda n\u00e4ha, aukartust \u00e4ratavat ja unustamatut vaatepilti. Aga mis p\u00f5hjustab virmalisi?<\/p>\n<\/div>\n<p>K\u00f5ik algab meie l\u00e4himast t\u00e4htest, P\u00e4ikesest. P\u00e4ike on uskumatult energiarikas ja tekitab pidevalt seda, mida nimetame p\u00e4ikesetuuleks \u2013 pisikeste osakeste voolu. Need lendavad kosmosesse ja suunatakse k\u00f5rvale Maa \u00fcmbritseva magnetv\u00e4lja poolt.<\/p>\n<p>Tavaliselt l\u00f5peb lugu siin\u2026 kuid m\u00f5nikord toimuvad P\u00e4ikesel tohutud pursed, mida nimetatakse p\u00e4ikesepurseteks ja mis muudavad p\u00e4ikesetuule veelgi tugevamaks. Kui see juhtub, on osakestel nii palju energiat, et nad ei lenda lihtsalt Maa magnetv\u00e4lja sisse \u2013 nad p\u00f5rkuvad sellega kokku!<\/p>\n<p>Seej\u00e4rel liiguvad p\u00e4ikesetuule osakesed Maa magnetv\u00e4lja m\u00f5jul meie planeedi p\u00f5hja- ja l\u00f5unapoolusele. L\u00f5puks p\u00f5rkuvad osakesed meie atmosf\u00e4\u00e4ris olevate gaasidega. Kogu see energia vabaneb seej\u00e4rel valguse kujul! P\u00e4ikesetuule osakesed, mis p\u00f5rkuvad hapnikuga, tekitavad imelise rohelise v\u00e4rvi. L\u00e4mmastik tekitab kauneid siniseid ja lillakaid toone. Just see p\u00f5hjustabki virmalisi.<\/p>\n<p>Nii ilus kui virmalised ka on, v\u00f5ivad p\u00e4ikesetuule muud k\u00f5rvalm\u00f5jud tekitada probleeme. K\u00f5rge energiaga osakesed v\u00f5ivad kahjustada meie planeedi orbiidil tiirlevaid satelliite ja ohustada astronautide turvalisust. Need v\u00f5ivad p\u00f5hjustada isegi elektrikatkestusi Maa pinnal. Virmalised ei esine ainult Maal. Ka m\u00f5nedel teistel meie P\u00e4ikeses\u00fcsteemi planeetidel, nagu Saturn ja Jupiter, on magnetv\u00e4ljad. P\u00e4ikesetuule osakesed v\u00f5ivad nendega kokku p\u00f5rkuda t\u00e4pselt samamoodi nagu Maaga!
