Is there life outside the solar system (太阳系)? There might be. Scientists are still trying to find the answer. They recently found water on a planet (行星) called K2-18b. The planet is like a “super Earth”. It is eight times heavier than Earth. It is 110 light-years away from us. Scientists say it has the right water and temperature (温度) for life. This is the first time scientists have found a planet like this.
