Nagu inimesedki, s\u00fcnnivad t\u00e4hed, vananevad ja surevad. Nende s\u00fcnnikohad on tohutud, k\u00fclmad gaasi- ja tolmupilved, mida nimetatakse \u2018uduiks\u2019. Neist k\u00f5ige kuulsam on Orioni udu, mis on n\u00e4htav palja silmaga.<\/p>\n<\/div>\n

Miljardid aastad p\u00e4rast oma s\u00fcndi, kui P\u00e4ikesega sarnane keskmise suurusega t\u00e4ht j\u00f5uab oma elu l\u00f5pule, paisub ta punaseks hiidt\u00e4heks. Selle l\u00e4bim\u00f5\u00f5t v\u00f5ib ulatuda miljonite kilomeetrite suuruseni \u2013 kui see juhtub P\u00e4ikesega, on ta piisavalt suur, et neelata endasse Merkuuri ja Veenuse!<\/p>\n

P\u00e4rast gaasi 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. Aga \u00e4rge muretsege, meie P\u00e4ikesega ei juhtu seda veel umbes 5 miljardi aasta jooksul!<\/p>\n

V\u00e4ikesed t\u00e4hed elavad kaua, \u00fcle 10 miljardi aasta. Nende surma pole kunagi t\u00e4heldatud, kuid arvatakse, et nad l\u00f5petavad oma elu vaikselt ja kustuvad l\u00f5puks \u00e4ra.<\/p>\n

\"Supernova
Supernoova j\u00e4\u00e4k<\/figcaption><\/figure>\n

Suurimad t\u00e4hed l\u00f5petavad oma elu v\u00e4ga ootamatult. Elu l\u00f5pupoole paisuvad nad punasteks hiidt\u00e4htedeks, enne kui l\u00f5puks tohutu supernoova plahvatuses end t\u00fckkideks purustavad.<\/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

Superhiiglases 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":"
