"However,we have not found life on any other planets yet. 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 like that of hte earth,so scientists do not think they will find life on them.The sun and its planets are called the solar system,and our solar system is a small part of a much larger group of stars and planets,called the Galaxy or the Milky Way.There are billions of stars in the Galaxy,and our sun is only one of them. Scientists have also discovered many other galaxy in the universe.They are very far away and their light has to travel for many yesrs to reach us.So how large is the universe?It is impossible to imagine. Scientists have sent spaceships to the planet Mars to take photos.They have even sent spaceships to travel ourside the solar system.However,no spaceship has travellde far enough to reach other stars in our Galaxy. Scientists have always askde the questions:with so many stars in the universe,are we alone,or is there life out there in space?Have there been visitors to the earth from other planets?Why has no one communicated with us?We do not know the answers...yet. 科学家们认为地球上存在生命已经有数亿年的时间了。 然而, 我们还没有在其他行星上找到生命。 地球是一颗行星, 它围绕太阳转。 其他七颗行星也围绕太阳转。 它们当中没有一个有像地球一样的环境, 所以科学家们认为他们不可能在其他星球上找到生命。 太阳和它的行星被叫作太阳系, 我们的太阳系是一个被称作银河系的大得多的恒星和行星群中的一小部分。 在银河系中有数十亿颗恒星, 我们的太阳只是它们其中的一个。 科学家们也已经在宇宙中发现了许多其他星系。 它们很遥远, 并且它们的光必须经过许多年才能到达我们这里。所以宇宙有多大?这很难想象。 科学家们已经发射了宇宙飞船到火星上去拍照片。 他们甚至发射宇宙飞船到太阳系以外遨游。 然而, 没有宇宙飞船能遨游到足够远而到达银河系的其他恒星上。 科学家们一直问这些问题: 宇宙中有这么多的星星, 我们是孤独的呢, 还是太空中还有其他生命存在呢? 有来自其他星球的访客来过地球吗? 为什么没有人和我们交流?我们仍然不知道答案.......
