Astronomy Science ~ The researchers say that Venus once had strange oceans possibilities that are made of carbon dioxide, which helps form the surface.

Venus is often described as a planet Earth's  twin because venus is almost similar to Earth in size, mass, distance and chemical composition. However, the earth is a haven for life, whilst Venus is usually depicted as hell, by destroying the atmosphere and corrosive sulfuric acid clouds that float on the surface of the rocky desert hot enough to melt lead.

Although Venus is currently very hot and dry, the planet may once have oceans like Earth. Previous research shows that in the past, Venus has enough water in the atmosphere to cover the entire surface of the planet in water as deep as 25 meters.

This image shows the surface of the northern hemisphere of Venus when observed by NASA's Magellan radar mapping spacecraft that peek into the thick clouds of Venus in 1994. Scientists now suspect Venus may have had oceans of carbon dioxide in the past.

Instead of a sea of ​​water, scientists now show that Venus may have had odd oceans made from liquid carbon dioxide. Carbon dioxide is very common on Venus. "Currently, Venus atmosphere consisting mostly of carbon dioxide, which covers 96.5 percent," said study lead author Dima Bolmatov, a theoretical physicist at Cornell University in Ithaca, New York

On Earth, these gases are known as greenhouse gases, help warm our planet, carbon dioxide exhaled by animals and used by plants in photosynthesis. Although these substances can be solid, liquid and gas, passing through the critical point the combined temperature and pressure, the carbon dioxide can be transformed into substance "supercritical". The supercritical fluid may have properties of both liquids and gases. For example, can dissolve substances like a liquid, but flow like gas.

To see what the effects of supercritical carbon dioxide on Venus, Bolmatov and colleagues studied the material properties of supercritical. There are still many who have not understood about these substances, he said. Scientists generally consider the physical properties of supercritical fluids changed with pressure and temperature. However, in computer simulations of molecular activities, Bolmatov and colleagues found that supercritical material can shift dramatically from a liquid to a gas.

The atmospheric pressure at the surface of Venus is now more than 90 times that of Earth, but in the early days of this planet, the surface pressure of Venus' could be tens of times larger. This can last for a relatively long period of time, 100 million to 200 million years. In such conditions, supercritical carbon dioxide with water such behavior may be formed, said Bolmatov.
