Why did the view of the sky from the surface of Venus appear tinted red?
Venus is surrounded by thick clouds and some of these clouds are made of sulfuric acid. We cannot really see through these thick clouds. The atmosphere itself is composed of carbon dioxide. … The one probe that made it to the surface of Venus showed red and brownish rocks.
Does Venus have water on its surface?
What Orbiter gave us the most detailed maps of Venus?
The orbiter that gave us the most detailed maps of Venus to date was Magellan. Venus is almost the same size mass and density as the Earth. As on Earth continent-like land masses cover over a quarter of the surface of Venus. Carbon dioxide is the predominant atmospheric gas on Venus.
Will Venus ever be habitable?
“We find an extensive early habitable period of some 900 million years indicating that liquid water on early Venus is much more likely than previously thought ” said Hoening.
Do you think life can exist on Venus planet Class 10?
No life does not possible on venus as due to atmosphere that contains H2SO4(Sulphuric acid) that acts as a dehydrating agent and hydrate water molecules so there is no H20 (Water) and Oxygen as the environment of earth.

-Venus’ atmosphere is composed of 96.5% carbon dioxide (CO2) and 3.5% nitrogen (N2). Also trace constituents of oxygen and water vapor have been detected. – clouds are made of sulfuric acid (H2SO4). Venus’ clouds are formed by photochemistry – chemical reactions driven by the energy of ultraviolet sunlight.
