However, we havent found life on other planets yet. Why not ? The Earth is a planet and it goes around the sun. Seven other planets also go around the Sun. None of them has an environment with air, so people and things cannot grow. The Sun and its planets are called the solar system. The solar system is a small part of our galaxy.The stars we see at night are the suns in other solar systems. There are more than 200 billion stars in our galaxy, called the Milky Way, and our Sun is only one of them.But scientists have discovered many other galaxies in the universe. They are a long way away and their light has travelled for many years to reach us. It is hard to understand how large the universe is.Scientists have sent lots of spacecraft to look at other planets in our solar system ,and some spacecraft have gone beyond the solar system. However, no one has discovered any life in space yet.But why has no one from other planets sent us a message? Have they tried to send information to us? With so many stars in the universe, are we alone, or is there life out there in space? We dont know yet.Answer some questions about the passage:1.Have we found life on Mars?2.How many planets are there in the solar system?3.Which is larger, the galaxy or the universe?4.What have scientists done to look at other planets?5.Is there life out there in space?No, we havent.Eight.The universe.They have sent lots of spacecraft.We dont know , we have never found any life on other planets .choose the best title.
