Vyshe samogo vysokogo zdaniya, vyshe samoi vysokoi gory, vyshe, chem mozhet podnyat'sya samolet, raskinulos' carstvo polyarnyh siyanii. Polyarnye siyaniya redko opuskayutsya nizhe 60 kilometrov, a ih verhnyaya granica mozhet dostigat' vysoty v 1000 kilometrov. Svechenie polyarnyh siyanii voznikaet, kogda elektrony i protony s vysokoi energiei stalkivayutsya s molekulami v atmosfere Zemli.
