Now seen as an extremely hot planet, Venus might have had oceans at a very early point in time. However, these seas would have been as hellish as the planet is today, being made not of water but of liquid of carbon dioxide. These oceans may have covered the whole planet having a depth ranging to 80 feet. Venus’ surface is believed to have been molded by these oceans of fluid carbon dioxide, according to a study published recently in The Journal of Physical Chemistry Letters.
The study was conducted under the supervision of Dima Bolmatov,, a theoretical physicist of New York’s Cornell University. His team of researchers created digital atomic model reproductions to see how Venus’ carbon dioxide behaves. They examined the features and effects of ‘supercritical’ carbon dioxide, which displays both fluid and gas properties. According to Dima Bolmatov the planet’s atmosphere is comprised of carbon dioxide in a 96.5 percent volume ratio.
As indicated by the study, the air pressure found in Venus’ atmosphere is about 90 times higher than that of our planet. Scientists believe that, in earlier times, Venus may have had a more increased atmosphere pressure for long periods of time ranging from 100 million to 200 million years.
The experts allege that the ‘supercritical’ carbon dioxide presenting fluid-like properties was probably shaped under those higher surface pressure circumstances. The lead researcher at Cornell University held that ‘supercritical’ carbon dioxide is likely to be the cause behind today’s landscape on Venus, sculpting fields, river- like beds or rift valleys.
The group of researchers additionally found that tight masses of supercritical carbon dioxide with gas-like features may have been similar to soap bubbles during the high pressure phase on Venus. Bolmatov explained that supercritical carbon dioxide would have looked like a gas bubble encompassed in a dense stratum of liquid.
The scientists trust that further examinations will also involve experiments aiming at observing when supercritical carbon dioxide changes its properties from gas-like to liquid-like.
Earth and Venus are very much alike. They display about the same mass and size and chemical composites. But while our planet is much like a heaven for life forms, Venus is more like an inferno. The air conditions on the shiny planet are deadly and its land fields are hot to the melting point. Venus is popular for its remarkably hot atmospheric conditions, being the hottest member of our earth’s planetary group with temperatures reaching regularly 462 degrees Celsius.
