Mightee writes "Astronomers these days are busy searching for life on other planets of the universe. They search for the environment and the necessary elements for establishing a habitat for Homo sapiens. After mars, it's Venus this time that has shown a green signal. Surprisingly it isn't NASA but the Venus Express spacecraft of 'the European Space Agency' who has found it.
The signal is actually the presence of Ozone layer similar to that surrounding our mother Earth and Mars already. It is a layer of Ozone (O3) surrounding the earth which absorbs harmful ultraviolet rays coming from the sun. It bears quite a lot importance in the presence of life on earth. In fact, it is thought to have been brought into being by the life itself."
