New Findings Underscore an Earth-Venus Kinship
Atmosphere
venus has a turbulent atmosphere
role of heat trapping gases like carbon dioxide shapes climate of planets
surface temperature on venus exceeds 800 degrees fahrenheit
this high temperature result from heat trapping effects of almost pure carbon dioxide
In Venus is as 100 times dense as Earth.
water
scientists believe that Venus is formed of liquid just like Earth
due to high sun light intensity,water began to evaporate
water vapour is one of the green house gases which trap in heat.
Due to acceleration in evaporation,all liquid water turned to thich atmosphere of water vapour
U.V rays splited floating water molecules to oxygen and hydrogen
chemical reaction with minerals in rocks transferred oxygen to carbon dioxide
Hydrogen escaped to space owing to its lightness
Size and Mass
Venus and earth have the same size and mass.
Composition
Venus and Earth have roughly the same composition
sun light
Venus is closer to sub than earth,,though,clouds reflect a large portion of sun light
Venus's enviroment
before space age,planetary scientists thought that venus and Earth have the same enviroment
They even assumed thatthere could be tropical jungles couvered by the non-ending cloud in Venus
Deauterium
it is a heavier version of Hydrogen
so it would escape more slowly to space
Venus express found that ratio of deturium to hydrogen is is 150 times high as on earth.
In venus,deuterium concentration turned out to be 2.5 times as high in the upper atmosphere than to the near ground
when they explore this they will be able to know the history of water
Lightening
On Earth radio waves are generated by lightening
Venus Express detected the bursts of radio waves known as “whistlers’’
In venus,clouds are different than that which produce thunderstorms in Earth.
clouds in Venus are like just a haze of sulphuric acid,On earth this kind of clouds dont produce electric charge that's why it's puzzling to have lightening.
