Enamikul t\u00e4htedel kulub surmani miljoneid aastaid. Kui P\u00e4ikesega sarnane t\u00e4ht on kogu oma vesinikuk\u00fctuse \u00e4ra p\u00f5letanud, paisub ta punaseks hiiglaseks. Selle l\u00e4bim\u00f5\u00f5t v\u00f5ib ulatuda miljonite kilomeetriteni \u2013 see on piisavalt suur, et neelata endasse Merkuuri ja Veenuse.<\/p>\n<\/div>\n

P\u00e4rast v\u00e4liskihtide \u00e4raheitmist kokkuvariseb t\u00e4ht ja moodustab v\u00e4ga tiheda valge k\u00e4\u00e4buse. \u00dcks teelusikat\u00e4is valge k\u00e4\u00e4buse ainet kaaluks kuni 100 tonni. Miljardite aastate jooksul jahtub valge k\u00e4\u00e4bus ja muutub n\u00e4htamatuks.<\/p>\n

T\u00e4hed, mille mass on \u00fcle kaheksa korda suurem kui P\u00e4ikese mass, l\u00f5petavad oma elu v\u00e4ga ootamatult. Kui neil k\u00fctus otsa saab, paisuvad nad punasteks hiidt\u00e4htedeks. Nad p\u00fc\u00fcavad elus p\u00fcsida, p\u00f5letades erinevaid k\u00fctuseid, kuid see \u00f5nnestub vaid m\u00f5ne miljoni aasta jooksul. Seej\u00e4rel purunevad nad tohutus supernoova plahvatuses.<\/p>\n

Umbes n\u00e4dala jooksul paistab supernoova kirkamalt kui k\u00f5ik teised t\u00e4hed selles galaktikas. Seej\u00e4rel kaob selle s\u00e4ra kiiresti. J\u00e4rele j\u00e4\u00e4b vaid pisike, tihe objekt \u2013 neutronit\u00e4ht v\u00f5i must auk \u2013, mida \u00fcmbritseb laienev v\u00e4ga kuuma gaasi pilv.<\/p>\n

Superhiiglase sisemuses tekkinud elemendid (nagu hapnik, s\u00fcsinik ja raud) on laiali pillutatud kogu kosmoses. Sellest t\u00e4hetolmust tekivad l\u00f5puks teised t\u00e4hed ja planeedid.<\/p>","protected":false},"excerpt":{"rendered":"
