Ve\u010dina zvezd umre \u0161ele po milijonih let. Ko zvezda, kot je Sonce, izgori vse svoje vodikovo gorivo, se raz\u0161iri in postane rde\u010da orjakinja. Njen premer lahko zna\u0161a milijone kilometrov \u2013 dovolj velik, da bi pogoltnila planeta Merkur in Venero.<\/p>\n<\/div>\n

Ko zvezda izpusti svoje zunanje plasti, se sesede in nastane zelo gosta bela pritlikavka. Ena \u010dajna \u017eli\u010dka snovi iz bele pritlikavke bi tehtala do 100 ton. V milijardah let se bela pritlikavka ohladi in postane nevidna.<\/p>\n

Zvezde, katerih masa je ve\u010d kot osemkrat ve\u010dja od Son\u010deve, svoje \u017eivljenje kon\u010dajo zelo nenadoma. Ko jim zmanjka goriva, se raz\u0161irijo v rde\u010de supervelikanke. Posku\u0161ajo pre\u017eiveti z izgorevanjem drugih vrst goriva, a to jim uspeva le nekaj milijonov let. Nato se razletijo v ogromni supernovni eksploziji.<\/p>\n

Pribli\u017eno en teden supernova zasen\u010di vse druge zvezde v svoji galaksiji. Nato hitro zbledi. Ostane le majhen, gost objekt \u2013 nevtronska zvezda ali \u010drna luknja \u2013, obdan z raz\u0161irjajo\u010dim se oblakom zelo vro\u010dega plina.<\/p>\n

Elementi, ki nastanejo v notranjosti supervelikana (kot so kisik, ogljik in \u017eelezo), se razpr\u0161ijo po vesolju. Iz tega zvezdnega prahu se s\u010dasoma oblikujejo druge zvezde in planeti.<\/p>","protected":false},"excerpt":{"rendered":"
