Unanswered questions about the planet Venus !

The surface of Venus is not suitable for life. It is barren, dry, crushed under an atmosphere about 90 times the pressure of Earth’s. The surface is also roasted by temperatures two times hotter than an oven. NASA’S Magellan mission last orbited Venus; twenty-seven years have passed since then. From that mission lot of information has been gathered about Venus.

Unanswered questions about Venus –

There has been lots of speculation about possible life on Venus. To find out whether life was ever possible on Venus 1st, the past environment of Venus have to understand by scientists. This involves studying the history, geology, the atmosphere of Venus.

Venus and Earth are similar in size and density, so that these planets could be very similar hypothetically. But they are different. Air pressure at the surface of the planet is 90 times that of Earth. The planet rotates on its axis backwards compared to the other planets in the solar system. The surface temperature is over 900 degrees Fahrenheit which makes it the hottest planet in the solar system. This extreme heat on the surface is due to a carbon dioxide atmosphere with thick sulfuric acid clouds. Venus represents an essential illustration of how planetary environments can evolve.

Scientists are still not aware whether Venus formed from the same early solar system materials as Earth and Mars. Still, it is not known whether Venus was bombarded by comets and asteroids, rich in water, the way Earth was. Understanding the water delivery to Venus is essential for evaluating its potential to host oceans in the past.

Scientists are still not aware of the essential trace chemicals in the Venus atmosphere. They do not understand the chemical cycles that provide clues to how it has evolved and the role of these chemical cycles in Venus’ history. The planet’s atmosphere is one of the biggest mysteries, especially the deep or lowermost atmosphere. Venus’ lower atmosphere carbon dioxide is heated and pressurized to the point where it acts more like a hot liquid than a gas.

The planet’s surface is still a mystery, especially in regions beyond the volcanic plains. Most of the surface is made of basalt, which is produced by volcanism. But some intriguing mountainous highland regions suggest hints of having a different composition. They may be made of rocks that form from water-rock interactions and continent-building processes. 

Venus’ past habitability cannot be accessed without knowing how much water Venus may have had and when and how it lost that water. Scientists can use the bulk chemical composition of rocks to unravel the mystery of water on the planet. The measurement of the atmosphere can also be used by scientists to understand the history of water on the planet.

Scientists are still discovering whether Venus ever had Earth-style plate tectonics and how those mountain-building processes are similar or different from Earth’s. If similar plate tectonics exist on Venus, now or in the past, the planet’s crust must experience the movement of crustal plates over geologic time, mid-ocean-ridge volcanism and subduction. The history of the planet’s tectonics still needs research, and there are many questions related to it unanswered. Another essential mystery about the surface of Venus is volcanism. It is still being speculated by scientists whether the planet’s surface is currently volcanically active and today eruptions occur to what degree.
