Over the past few decades, both Russia and the USA have sent space probes to Venus to discover what that planet's environment is like. The results have astounded the scientific world. It had always been assumed, prior to the probes, that the environment around Venus was similar to that of the earth. Venus had even been called our sister planet based on the fact that both planets are about the same size, were created at the same time, from the same materials and in the same manner. But the probes found that, in direct opposition to earth's friendly, life supporting atmosphere, the environment on Venus is deadly.
Nothing can exist there.
It has a crushing corrosive atmosphere which immediately destroys all things - inanimate as well as living. The probes reported the normal or average temperature on Venus to be around 800 degrees. Deadly clouds of corrosive gases swirl through its atmosphere. The atmospheric pressure of the planet is so great, the heat so intense and the gases so destructive that the probes sent to explore the planet could only do so from high above its deadly surface. When they ran out of power and fell into the denser lower levels of the atmosphere, they were completely destroyed.
