M\u00e9g a legnagyobb t\u00e1vcs\u00f6vekkel is nagyon neh\u00e9z r\u00e9szleteket megfigyelni a Marson. Az 1800-as \u00e9vek v\u00e9g\u00e9n egyes tud\u00f3sok \u00fagy v\u00e9lt\u00e9k, hogy egyenes vonalakat l\u00e1tnak a bolyg\u00f3 felsz\u00edn\u00e9n. Ezek a vonalak z\u00f6ldes ter\u00fcleteket k\u00f6t\u00f6ttek \u00f6ssze, amelyek \u00fagy n\u00e9ztek ki, mintha n\u00f6v\u00e9nyzettel lenn\u00e9nek bor\u00edtva. Ezek a tud\u00f3sok azt hitt\u00e9k, hogy az egyenes vonalak a marslak\u00f3k \u00e1ltal \u00e9p\u00edtett csatorn\u00e1k, amelyek a vizet a term\u0151f\u00f6ldjeikre vezetik.<\/p>\n<\/div>\n

Az \u0171rszond\u00e1k \u00e1ltal k\u00e9sz\u00edtett felv\u00e9telekb\u0151l kider\u00fclt, hogy ezek a csatorn\u00e1k nem l\u00e9teznek. A bolyg\u00f3n nincs nyoma semmif\u00e9le \u00e9letnek \u2013 sem n\u00f6v\u00e9nyeknek, sem intelligens marslak\u00f3knak. Ma m\u00e1r tudjuk, hogy a Mars egy nagyon hideg, sz\u00e1raz bolyg\u00f3, ahol foly\u00e9kony v\u00edz nem l\u00e9tezhet a felsz\u00ednen. A sarkvid\u00e9ki sapk\u00e1kban azonban nagy kiterjed\u00e9s\u0171 v\u00edzj\u00e9g tal\u00e1lhat\u00f3. A fagyott talajban is rengeteg j\u00e9g van \u2013 hasonl\u00f3an az \u00e9szak-kanadai \u00e9s oroszorsz\u00e1gi permafrost-ter\u00fcletekhez.<\/p>\n

A nagy, kisz\u00e1radt csatorn\u00e1k is arra utalnak, hogy egykor rengeteg foly\u00f3v\u00edz volt a felsz\u00ednen. A Mars Express \u00e9s m\u00e1s \u0171reszk\u00f6z\u00f6k leg\u00fajabb eredm\u00e9nyei szerint a f\u00f6ld m\u00e9ly\u00e9n foly\u00e9kony v\u00edz lehet. Ha a Mars egykor melegebb \u00e9s nedvesebb volt, akkor lehets\u00e9ges, hogy \u00e9let alakult ki a v\u00f6r\u00f6s bolyg\u00f3n. Egyszer\u0171 \u00e9letform\u00e1k, p\u00e9ld\u00e1ul bakt\u00e9riumok, m\u00e9g mindig l\u00e9tezhetnek a fagyott felsz\u00edn alatt.<\/p>\n

1996-ban egy tud\u00f3scsoport bejelentette a vil\u00e1gnak, hogy bizony\u00edt\u00e9kot tal\u00e1ltak bakt\u00e9riumok jelenl\u00e9t\u00e9re egy a Marsr\u00f3l sz\u00e1rmaz\u00f3 meteorit belsej\u00e9ben. Ez az elm\u00e9let azonban a t\u00f6bbi tud\u00f3s k\u00f6r\u00e9ben nem t\u00fal n\u00e9pszer\u0171. Ha a j\u00f6v\u0151ben \u00e9letet tal\u00e1ln\u00e1nak a Marson, az lenne az els\u0151 bizony\u00edt\u00e9k arra, hogy nem vagyunk egyed\u00fcl az Univerzumban.<\/p>","protected":false},"excerpt":{"rendered":"
