Scientists do not understand everything about the universe. They disagree about some important facts. For example, is it getting larger or smaller? Although they don\'t agree about everything, there are some facts about the universe which they are sure about. Take the planet Venus, for example. Here the temperature reaches over 400. And another unusual fact about Venus is that a day there lasts longer than a year. Many scientists are still searching for life in other parts of the universe. Are they looking for life on Venus? It doesn\'t seem to be the kind of place where life might exist. The atmosphere of Venus consists mainly of carbon dioxide. And it has an air pressure 90 times greater than that of Earth.
