Scientists have been investigating where all the water in the atmosphere of Venus disappeared to.
With surface temperatures exceeding 860 degrees and crushing atmospheric pressures that are more than 100 times those found on the Earth, it is certainly no surprise that Venus is bone dry.
The big question however is where did its water actually go ? Any water that boiled off the surface should have ended up as steam in the atmosphere but there is next to no moisture there at all – roughly 10,000 to 100,000 times less than can be found in the atmosphere of the Earth.
The answer, scientists believe, lies in the strong electrical field surrounding the planet.
“It turns out that Venus’s electric field is at least 5 to 10 times stronger than on Earth,” said NASA’s Glyn Collinson. “It can rip heavy things, like oxygen, straight out of the upper atmosphere and send them kicking and screaming off into space.”
This is significant, because it not only explains how the water on Venus was lost once it was broken down in to oxygen and hydrogen ions but it could also be an important factor to consider in the hunt for Earth-like worlds around distant stars. – See more at: http://www.unexplained-mysteries.com/news/295888/what-happened-to-all-the-water-on-venus#sthash.ciLv8oqs.dpuf
