Origins of the Moon

Scientists have found traces of another world on the Moon. Analyzing rocks brought back from the Moon to Earth by Apollo astronauts, they have found minerals that differ from what you would expect. They see this as proof of the theory that the Moon was formed from debris from a planetary collision about 4.5 billion years ago, when Earth collided with another celestial body in the very beginning of the history of our solar system. This is interesting, isn't it? It does not really matter that it is of no consequence to our everyday life. Science does not always have to be, it still gives us this sense of wonder, when it provides us with a greater understanding of the world around us. This is good in itself.
