Pfupisa nyaya yacho:  Enda kunzvimbo dzinopisa nhasi uye uchawana tembiricha dzakanaka dzegore negore dze30°C (85°F). Asi enda ikoko makore mabhiriyoni 2,4 apfuura, uye sezvingabvira waizova wakabatwa namatembiricha akafanana neArctic e -40°C (-40°F). Iyi dzidziso inonzi "Snowball Earth" inoratidza kuti pasi redu rakambenge raoma nechando chose chose - uye zvingava nemigumisiro yokuwana upenyu pane dzimwe nyika dzakaoma nechando dzakadai seEuropa neEnceladus. Mumwe musayendisiti weUniversity of Cologne akatungamirira kutsvakurudza achitaura pfungwa itsva. Kunoratidza kuti tembiricha paEquator yePasi yaiva -40°C (-40°F) makore mabhiriyoni 2.4 akapfuura (mufananidzo womufananidzo unoratidzwa). Zvikonzero nei nyika yose yakaoma nechando hazvinzwisiswi. Asi zvingava nemigumisiro yokuwana upenyu pamwedzi yakaoma nechando yakadai seEuropa. Kutsvakurudza uku, kwakatungamirirwa naDr Daniel Herwartz vepaUniversity of Cologne, kwakabudiswa muProceedings of the National Academy of Sciences. Kunoratidza kuti Pasi rose rakava ne"kuoma nechando kwakadzika", uye makungwa akachinja kuva chando chakakura mamita 300 pakukora. Ikoku kunoreva kuti, kana upenyu hwaizopukunyuka panguva iyeyo, sezvingabvira hwaizofanira kuramba huri mumvura yakadzika pasi pevhu, pasi peiri ganda rine chando. Padzimwe nyika dziri muSystem yedu yeZuva dzakadai seEuropa, tinoona chimiro chakafanana chechando - uye tine chivimbo chakakwana chokuti iyowo ine gungwa rine mvura pasi pevhu. Nyika yakaoma nechando, yakafanana nePasi, iri kutenderera imwe chete yenyeredzi mbiri ingavandudza mikana yokuwana upenyu hwokumwe. Nyika yacho, iri kure nemakore chiedza 3.000, yakakura kaviri kupfuura Pasi uye inenge iri kure nenyeredzi yayo sezvinoita Pasi kubva kuzuva. Inonzi OGLE-2013-BLG-0341LBb, nyeredzi inogara papuraneti iyi inopenya zvakapetwa ka400 pane zuva. Yakarondedzerwa seshanduro yechokwadi yepasi rechando Hoth inoratidzwa muStar Wars sequel The Empire Strikes Back. Asi vaongorori venyeredzi vepaOhio State University vakataura kuti nyika imwe chete iyoyo inotenderera nyeredzi yakafanana nezuva yaizova'munzvimbo inogarwa' umo mamiriro ezvinhu angave akakodzera mvura yakaita semvura uye upenyu.

Nyanzvi yesayenzi yeYunivhesiti yeCologne yakatungamirira kutsvakurudza ichitaura dzidziso itsva. Zvinoratidza kuti tembiricha yaiva paEquator yaiva - 40 ° C makore mabhiriyoni 2,4 akapfuura. Zvikonzero nei nyika yose yakanga yaoma nechando hazvinzwisiswi. Asi zvingava nemigumisiro yokuwana upenyu pamwedzi yakaoma nechando yakadai seEuropa.
