    Two far-off planets are likely made of water,according to NASA's research.They're "unlike any planets found in our solar system".
    The system they studied is called Kepler-138 because it's located within the field of vision of NASA's Kepler spacecraft.Researchers have known about the existence of three outer planets within the Kepler-138 system,but have only just discovered two of them are likely made out of water.
    They also discovered evidence for a fourth planet that hadn't been described before.But the finding isn't as clear as it might seem.The scientists didn't directly discover water at planets Kepler-138 c and Kepler-138 d.Instead,they compared the sizes and masses of the planets to models for comparison.When doing so,they found that "up to half of their volume (体积) should be made of materials that are lighter than rock,but heavier than hydrogen or helium(氦)"
    "We previously thought that planets that were a bit larger than Earth were big balls of metal and rock," said Bjorn Benneke,the study's co-author. "However,we have now shown that these two planets,Kepler-138 c and d,are quite different in nature and that a big part of their entire volume is likely made up of water."
    The high temperatures on these planets mean they might be enveloped in an atmosphere of steam,according to NASA."The temperature in Kepler-138 d's atmosphere is likely above the boiling point of water,and we expect a thick atmosphere made of steam on this planet," Bjorn said. "Only,under that steam atmosphere there could possibly be liquid water at high pressure."
    The "water worlds" are outside their star's habitable place—the area in which temperatures allow liquid water on the surface of a rocky planet,possibly supporting life.But the new planet described by the researchers,Kepler 138-e,does fall into that just-right area,according to the research.

  • 1.    Chen Xingrong's favorite activity is hopping onto the swing and dangling around,set up by his father to help him learn how to swim without water.
        "When he is happy,he jumps on the swing and smiles from ear to ear," says Chen's father Chen Xunhu. "But he is a big boy now,and the swing has become a bit too small for him."
        Chen Xingrong,16,was diagnosed with autism when he was a baby.
        Autism is a neurodevelopmental disorder characterized by varying degrees of impairment in communication skills and social interactions.

        Chen Xingrong could not utter a word until he was 2 years old.After being diagnosed with autism,his parents were worried.
        Chen Xunhu began traveling to big cities to learn more about autism.He quit his job and devoted his full attention to the topic of autism.
        In 2012,Chen Xunhu learned that swimming could help people with autism so he spent months learning how to swim by watching videos and reading books.
        "I spent three months teaching my son,but the efforts were in vain," he recalls.
        To his surprise,after another three months,he discovered that his son had developed the ability to control his breath under water,which significantly boosted his confidence.
        In October,the father took his son to participate in the 11th National Paralympic Games and the eighth Special Olympics.
        His son managed to claim five medals,including a gold.
        As well as swimming,learning basic life skills is also an important part of life for a teenager with autism.
        Chen Xunhu has made great efforts to make people in their community understand autism better.
        In 2010,an autism-themed film,titled Ocean Heaven,hit the big screen in China. It depicts how a terminally ill father attempts to teach his son the necessary life skills to live without him.
        Thereafter,Chen Xunhu organized about 500 people to watch the film together hoping the public to know more about autistic people
        Thanks to his father's perseverance,Chen Xingrong has learned to buy food in the market.He also does voluntary jobs at supermarkets and fast-food restaurants.
