Venus is far too hot to have any ice on it. Venus's surface is shrouded in a heavy layer of carbon dioxide atmosphere. Water ice is found where the temperature is below the freezing point of water and there is enough precipitation to fall snow or ice crystals or where there is water that may freeze. On Earth, for example, deep within our planet there is liquid water which does not freeze even at high altitude.
However, there is evidence that suggests that perhaps some of the oceans that covered much of Venus many years ago has now frozen over. Scientists think that this may have happened as soon as 500 million years ago when Venus's climate was very different to today. Then, the planet may have had clouds made of sulphuric acid which would have burned away any ice.
Furthermore, studies of its gravity suggest that there might be an ocean under the crust which would provide another source of water. But the fact that it is so hot means that any water that did exist would be quite dry.
Nevertheless, these are just theories and we will never know for sure unless we go there!
However, because Venus is so hot, snow as we know it cannot exist. Instead, the snow-capped mountains are topped with two metals: galena and bismuthinite. As we now know, the snow on Venus's surface is probably more akin to frost. Temperatures in the lowest Venusian plains reach a scorching 480 degrees Celsius (894 degF).
Galena is used in jewelry and as ballast for ships; bismuth is used in medicine and electronics.
Venus has an extremely dense atmosphere made mostly of carbon dioxide. It has a pressure at ground level of about 90 times that of Earth's. Because of its mass, the atmosphere acts like a giant cushion surrounding Venus. The planet's days are incredibly long - approximately 224 Earth days - due to this lack of air movement.
The presence of metal on Venus was discovered by the Magellan spacecraft, which showed evidence of galena while exploring the planet's surface in 1990 and 1991. Scientists have also found bismuth on the planet's surface. Galena is used as a source of lead and bismuth is used in medicine.
People have been thinking about colonizing other planets for years. In fact, the first artificial satellite, Sputnik, was sent up by the Soviet Union in 1957. Since then, many other satellites have been sent into orbit around Earth but nobody else yet knows how to make use of them!
Venus's surface temperature is constant. It doesn't grow any cooler when one moves closer to the poles, at night, or with any of the other factors that impact the temperature on Earth. The only way for Venus to have ice at its north and south poles is if it has been frozen there for a long time--and even then, it would be more ice than water.
Earth's atmosphere reflects about 90% of the sun's heat back to space, while Venus's atmosphere reflects almost all of it. This is why Venus is so hot. Its atmosphere prevents any part of its surface from cooling off. Even though Venus is always the same distance from the Sun, due to its orbit being slightly elliptical instead of circular, some parts of its surface are in darkness for several months at a time.
It is believed that over time, all terrestrial planets will become covered in oceans, but how long this takes depends on their sizes and distances from the sun. For example, because Jupiter is so far away from the sun, it will take millions of years before it becomes oceanic. But Neptune, which is also far away from the sun, could become oceanic in just a few hundred thousand years.
Venus's surface is exceedingly arid. UV radiation from the sun drained water swiftly during its development, keeping the planet in a molten state for an extended period of time. Today, there is no liquid water on its surface because the blistering heat produced by its ozone-rich atmosphere would cause water to boil away. However, under the right conditions, such as when Earth and Venus were closer together than they are today, there might have been oceans of superheated steam on Venus.
Earth also has dry ice in some places, such as Antarctica. Although there is probably less than 1% water vapor in the entire atmosphere of Venus, there is a lot of it around if you know where to look. The problem is that most of it is hidden beneath an opaque layer of sulfuric acid that destroys any attempts at remote sensing from space. But if you go down into the clouds where there is moisture, then your eyes will tell you about 10 times more water than what is in the gas phase with the air above it.
The correct answer is "Yes and No". Venus does have water in the form of vapour, but it's not really "liquid" water because it's always in a fluid state below 200°C (392°F).
The Sun emits ultraviolet light that has broken down hydrogen molecules in the atmosphere of Venus into their component elements over time. This leaves the planet completely covered in oxygen.
The surface of Venus is exceedingly arid. Today, there is no liquid water on its surface because the blistering heat produced by its ozone-filled atmosphere would cause water to boil away instantly. However many discoveries have been made about water on other planets including Earthlings' nearest neighbor, which shows evidence that it had at one time been flooded with water.
In addition, there are now suggestions that Earth may have been visited by intelligent aliens using technology that could fling matter into space, such as rocks.
Venus was originally thought to be similar to Earth, but subsequent research has shown it to be quite different. For example, its rotational speed is almost twice that of Earth while its orbit is only slightly wider.
This means that Venusian days are longer than Earth days, and this in turn means that there is more daylight when the Sun is high in the sky which should bring about greater warming. But actually, the reverse happens: Venus is always hot inside its shell of clouds and carbon dioxide gas. It gets too cold for life early in its history, before the Sun became much brighter and hotter.
As well as clouds, Venus has a dense atmosphere composed of gases such as sulfuric acid, oxygen, nitrogen, and carbon dioxide.
