Giup minh bai doc voi moi nguoiii NASA has made a huge alien breakthrough after they discovered three planets in a newly discovered star system which are similar to Earth and are scientists’ greatest chance yet at finding life. Using a robotic telescope operated by Liverpool John Moores University, NASA has discovered seven planets which are similar in size to Earth, rocky and probably have ocean. Six of the planets are in the habitable zone of a star known as TRAPPIST-1 which is 39 light years from Earth. The six habitable planets have a surface temperature ranging from zero to 1000C - the temperature region which is perfect for supporting life. Of these six, at least three of the planets have an ocean – and scientists state that anywhere on Earth you find water, you are likely to find life, which is why astronomers look for these on other planets. Thomas Zurbuchen, an associate administrator at NASA Headquarters in Washington, said: “The discovery gives us a hint that finding a second earth is not just a matter of it but when. Are we alone out there, we are making a leap forward to answering this question.” 1. What is true about the seven planets discovered? A. They are the same size as Earth. B.

A. an area that is close to star B. an area where humans can live C. an area that is at least 39 light years away from Earth. D. an area where life can exist 3. What is true about the six habitable planets? A. They orbit the star TRAPPIST-1. B. The temperature on the planets is 1000C. C. They have water. D. Three of these planets have life. 4. Why do scientists look for water when they find new planets? A. If there is water, there is life B. It is easiest to find. C. There’s a high chance of finding life. D. Water is not necessary for life. 5. What does the discovery of these Earth-like planets mean? A. There are aliens. B. We will soon find a second Earth. C. We are alone in the universe. D. We are closer to finding if there is life beyond Earth.
