We have always been interested in the Moon. 2, 000 years ago people already knew it circles around the Earth and it is in different places in the sky at different times of the year. At that time, everything about the Moon was learned by watching it carefully in the sky.
When scientists could use telescopes (望远镜) to study the Moon more clearly.. Their ideas began to change. They could see that there were lots of rocks on the surface of the Moon. Most scientists thought Moon rocks would be different from the rocks on the Earth.
in 1969, moon rocks were finally brought to the earth and studied. much to their surprise, scientists found that, except for water, the Moon and the Earth were made of the same things. Once again new ideas came out according to the new information.
After years of study, most scientists now think that the Moon was once part of the Earth. They believe about 4 million years ago, something of the same size as Mars hit the Earth. This sent billions of rocks into space around the Earth. These rocks slowly joined together and at last became the Moon.
In the future, our ideas about the Moon may change again. However, we will still be interested in the Moon.
