New Findings Underscore an Earth-Venus Kinship -make up

Recent discoveries have highlighted the intriguing similarities and differences between Earth and Venus. Initially, scientists believed that Venus might have a similar environment to Earth, potentially even tropical jungles beneath its perpetual cloud cover.

New Findings Underscore an Earth-Venus Kinship

Main topic

Lightening

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.
In venus,clouds are different than that which produce thunderstorms in Earth.
Venus Express detected the bursts of radio waves known as “whistlers’’
On Earth radio waves are generated by lightening

Deauterium

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
Venus express found that ratio of deturium to hydrogen is is 150 times high as on earth.
it is a heavier version of Hydrogen
so it would escape more slowly to space

Venus's enviroment

They even assumed thatthere could be tropical jungles couvered by the non-ending cloud in Venus
before space age,planetary scientists thought that venus and Earth have the same enviroment

sun light

Venus is closer to sub than earth,,though,clouds reflect a large portion of sun light

Composition

Venus and Earth have roughly the same composition

Size and Mass

Venus and earth have the same size and mass.

water

U.V rays splited floating water molecules to oxygen and hydrogen
Hydrogen escaped to space owing to its lightness
chemical reaction with minerals in rocks transferred oxygen to carbon dioxide
Due to acceleration in evaporation,all liquid water turned to thich atmosphere of water vapour
due to high sun light intensity,water began to evaporate
water vapour is one of the green house gases which trap in heat.
scientists believe that Venus is formed of liquid just like Earth

Atmosphere

In Venus is as 100 times dense as Earth.
surface temperature on venus exceeds 800 degrees fahrenheit
this high temperature result from heat trapping effects of almost pure carbon dioxide
role of heat trapping gases like carbon dioxide shapes climate of planets
venus has a turbulent atmosphere
