Az emberekhez hasonl\u00f3an a csillagok is megsz\u00fcletnek, meg\u00f6regednek \u00e9s meghalnak. Sz\u00fclet\u00e9si hely\u00fck hatalmas, hideg g\u00e1z- \u00e9s porfelh\u0151k, amelyeket \u2018k\u00f6d\u00f6knek\u2019 nevez\u00fcnk. Ezek k\u00f6z\u00fcl a legh\u00edresebb az Orion-k\u00f6d, amely szabad szemmel is alig l\u00e1that\u00f3.<\/p>\n<\/div>\n

Ezek a felh\u0151k saj\u00e1t gravit\u00e1ci\u00f3juk hat\u00e1s\u00e1ra \u00f6sszezsugorodni kezdenek. Ahogy a felh\u0151 egyre kisebb lesz, csom\u00f3kra szakad sz\u00e9t. Minden egyes csom\u00f3 v\u00e9g\u00fcl annyira felmelegszik \u00e9s s\u0171r\u0171v\u00e9 v\u00e1lik, hogy magreakci\u00f3k indulnak be benne. Amikor a h\u0151m\u00e9rs\u00e9klet el\u00e9ri a 10 milli\u00f3 Celsius-fokot, a csom\u00f3b\u00f3l \u00faj csillag sz\u00fcletik.<\/p>\n

Sz\u00fclet\u00e9s\u00fck ut\u00e1n a legt\u00f6bb fiatal csillag egy lapos g\u00e1z- \u00e9s porkorong k\u00f6zep\u00e9n helyezkedik el. Ezen anyag nagy r\u00e9sze v\u00e9g\u00fcl a csillag sug\u00e1rz\u00e1sa hat\u00e1s\u00e1ra elsz\u00e1ll. Miel\u0151tt ez megt\u00f6rt\u00e9nne, bolyg\u00f3k alakulhatnak ki a k\u00f6zponti csillag k\u00f6r\u00fcl.<\/p>\n

Az infrav\u00f6r\u00f6s obszervat\u00f3riumok k\u00e9pesek \u00e9rz\u00e9kelni a l\u00e1thatatlan csillagokt\u00f3l sz\u00e1rmaz\u00f3 h\u0151t, amelyek az ilyen felh\u0151k belsej\u00e9ben alakulnak ki. Ezek k\u00f6z\u00fcl az egyik leger\u0151sebb az ESA Herschel \u0171robszervat\u00f3riuma, amelyet 2009 m\u00e1jus\u00e1ban ind\u00edtottak \u00fatj\u00e1ra. A Herschel legal\u00e1bb h\u00e1rom \u00e9vet fog azzal t\u00f6lteni, hogy tanulm\u00e1nyozza azokat a poros felh\u0151ket, ahol \u2013 nagyok \u00e9s kicsik egyar\u00e1nt \u2013 csillagok sz\u00fcletnek.<\/p>","protected":false},"excerpt":{"rendered":"
