A V\u00e9nusz a Naphoz k\u00e9pest a m\u00e1sodik bolyg\u00f3, ez\u00e9rt az \u00e9gen mindig meglehet\u0151sen k\u00f6zel van a Naphoz. Ragyog\u00f3 reggeli vagy esti \u201ccsillagk\u00e9nt\u201d l\u00e1that\u00f3 \u2013 a Holdon k\u00edv\u00fcl az \u00e9jszakai \u00e9gbolt legf\u00e9nyesebb \u00e9giteste. T\u00e1vcs\u0151vel megfigyelhet\u0151, hogy \u2013 ak\u00e1rcsak a Hold \u2013 k\u00fcl\u00f6nb\u00f6z\u0151 f\u00e1zisokon megy kereszt\u00fcl.<\/p>\n<\/div>\n

A V\u00e9nusz az\u00e9rt olyan f\u00e9nyes, mert felh\u0151k bor\u00edtj\u00e1k, amelyek a be\u00e9rkez\u0151 napf\u00e9ny nagy r\u00e9sz\u00e9t visszat\u00fckr\u00f6zik. A s\u00e1rg\u00e1s felh\u0151k k\u00e9nb\u0151l \u00e9s k\u00e9nsavb\u00f3l \u00e1llnak.<\/p>\n

Bizonyos szempontb\u00f3l a V\u00e9nusz a F\u00f6ld ikertestv\u00e9re. M\u00e9rete nagyj\u00e1b\u00f3l megegyezik a F\u00f6ld\u00e9vel, \u00e9s ugyanazokb\u00f3l a k\u0151zetes anyagokb\u00f3l \u00e1ll. Emellett k\u00f6zelebb ker\u00fcl hozz\u00e1nk, mint b\u00e1rmelyik m\u00e1sik bolyg\u00f3. Ugyanakkor vastag sz\u00e9n-dioxid-l\u00e9gk\u00f6r bor\u00edtja \u2013 ez az a g\u00e1z, amit kil\u00e9legz\u00fcnk. Ez a l\u00e9gk\u00f6r olyan s\u0171r\u0171, hogy \u00e1ts\u00e9t\u00e1lni rajta olyan lenne, mintha v\u00edzben g\u00e1zoln\u00e1nk.<\/p>\n

A sz\u00e9n-dioxid a Nap h\u0151j\u00e9nek nagy r\u00e9sz\u00e9t visszatartja. A felh\u0151r\u00e9tegek is takar\u00f3k\u00e9nt hatnak. Ennek eredm\u00e9nyek\u00e9nt kialakul egy \u201celfajult \u00fcvegh\u00e1zhat\u00e1s\u201d, amelynek k\u00f6vetkezt\u00e9ben a bolyg\u00f3 h\u0151m\u00e9rs\u00e9klete 465 \u00b0C-ra emelkedett, ami el\u00e9g magas ahhoz, hogy az \u00f3lom megolvadjon. Ez azt jelenti, hogy a V\u00e9nusz m\u00e9g a Merk\u00farn\u00e1l is forr\u00f3bb.<\/p>\n

K\u00fcl\u00f6nleges v\u00e9delem n\u00e9lk\u00fcl a V\u00e9nuszra \u00e9rkez\u0151 l\u00e1togat\u00f3 azonnal meghalna \u2013 a hatalmas l\u00e9gnyom\u00e1s \u00f6sszet\u00f6rn\u00e9, a l\u00e9gk\u00f6r megfojtan\u00e1, a perzsel\u0151 h\u0151s\u00e9g porr\u00e1 \u00e9getn\u00e9, a sav pedig feloldan\u00e1.<\/p>\n

A V\u00e9nusz felsz\u00edn\u00e9t radarral t\u00e9rk\u00e9pezt\u00e9k fel. A t\u00e9rk\u00e9pek t\u00f6bb ezer vulk\u00e1nt \u00e9s becsap\u00f3d\u00e1si kr\u00e1tert \u00e1br\u00e1zolnak. K\u00e9t f\u0151 hegyvid\u00e9ki ter\u00fclet tal\u00e1lhat\u00f3, amelyek k\u00f6z\u00f6tt van egy, az Everestn\u00e9l is magasabb hegyl\u00e1nc.<\/p>\n

T\u00f6bb tucat \u0171reszk\u00f6z j\u00e1rt m\u00e1r a V\u00e9nuszon, de m\u00e9g mindig sz\u00e1mos rejt\u00e9ly \u00f6vezi a bolyg\u00f3t. Az ESA Venus Express szond\u00e1ja 2006 \u00e1prilis\u00e1ban \u00e9rkezett meg a bolyg\u00f3hoz, \u00e9s az\u00f3ta a V\u00e9nusz k\u00f6zel-pol\u00e1ris p\u00e1ly\u00e1j\u00e1n kering. M\u0171szereinek t\u00f6bbs\u00e9ge a s\u0171r\u0171 l\u00e9gk\u00f6rt \u00e9s a gyorsan mozg\u00f3 felh\u0151ket tanulm\u00e1nyozza, illetve azt vizsg\u00e1lja, hogy a Nap milyen hat\u00e1ssal van a bolyg\u00f3ra. Infrav\u00f6r\u00f6s \u00e9rz\u00e9kel\u0151je azonban a felsz\u00edn egy r\u00e9sz\u00e9t is felt\u00e9rk\u00e9pezte, \u00e9s kimutatta, hogy a F\u00f6ld szomsz\u00e9dj\u00e1n akt\u00edv vulk\u00e1nok is l\u00e9tezhetnek.<\/p>","protected":false},"excerpt":{"rendered":"
