Maast m\u00f6\u00f6da lendav tulnukas ei saaks vaevalt m\u00e4rkamata j\u00e4tta, et meie sinine planeet on suures osas ookeanidega kaetud. Siiski on Maa meie P\u00e4ikeses\u00fcsteemis ainus veega kaetud planeet. Kuna veerikkad planeedid tunduvad olevat \u00fcsna haruldased, ei ole \u00fcllatav, et teadlased on elevil seoses esimese avastusega, mille kohaselt on kaugel asuva t\u00e4he orbiidil tiirleval planeedil veerikas atmosf\u00e4\u00e4r.<\/p>\n<\/div>\n

Teada on \u00fcle 200 sellist \u2018p\u00e4ikeses\u00fcsteemiv\u00e4list\u2019 planeeti, kuid v\u00e4ga v\u00e4heseid neist on pildistatud v\u00f5i otseselt vaadeldud. \u00d5nneks on m\u00f5nda neist \u2018n\u00e4htamatutest\u2019 planeetidest v\u00f5imalik avastada, kui nad teevad transiiti ehk liiguvad oma t\u00e4he eest l\u00e4bi. Just nii avastati 2005. aastal gaasigigant, mida tuntakse nimetusega HD 189733b. See Jupiteri-taoline planeet p\u00f5hjustas oma emat\u00e4he valguse kerget tuhmumist.<\/p>\n

Infrapunakiirguses n\u00e4htav transiit-eksoplaneet HD 189733b<\/figcaption><\/figure>\n

Sellest ajast alates on Euroopa ja Ameerika teadlased HD 189733b-d t\u00e4iendavalt uurinud. NASA Spitzeri kosmoseteleskoobi abil m\u00f5\u00f5tsid nad t\u00e4helt p\u00e4rinevat infrapunakiirgust. Kui planeet liikus aeglaselt \u00fcle t\u00e4he ketta, blokeeris selle v\u00e4limine atmosf\u00e4\u00e4r \u00fchte lainepikkust rohkem kui teisi lainepikkusi. Ainus seletus sellisele heleduse v\u00e4henemise mustrile on veeauru olemasolu planeedi atmosf\u00e4\u00e4ris.<\/p>\n

Kahjuks puudub sellel hiidplaneedil kivine pind, kus v\u00f5iksid tekkida ookeanid. Lisaks tiirleb see oma t\u00e4he \u00fcmber \u00e4\u00e4rmiselt l\u00e4hedal. Atmosf\u00e4\u00e4ri temperatuur on \u00fcle 700 \u00b0C, mist\u00f5ttu on seal liiga kuum, et saaks sadada. Auru t\u00e4is HD 189733b on peaaegu kindlasti elutu. Siiski annavad need tulemused lootust, et mitte liiga kauges tulevikus leitakse veerikkaid, Maale sarnaseid planeete.<\/p>","protected":false},"excerpt":{"rendered":"
