NASA has been building a new telescope, called James Webb Space Telescope. Scientists think it could help them search for signs of alien life! They can watch exoplanets (外行星) with the help of the new telescope. So far, all the exoplanets we have found are too distant to send astronauts...
NASA said its Kepler spacecraft has spotted “Earth's bigger, older cousin”: the first nearly Earth-size planet to be found in the habitable zone of a star similar to our own.Though NASA can't say for sure whether the planet is rocky like ours or has water and air, it's the close...

The new telescope should be able to find out if the exoplanets have oxygen on them.Oxygen is a gas.On the earth,all animals need to breathe oxygen to live.It's produced by plants and some bacteria(细菌).This means if there is oxygen on a planet,there might be living things as well....

NASA’s James Webb Space Telescope has discovered a planet where it rains sand, in ground-breaking observation. The planet, WASP-107b, lying 200 light years away, was discovered in 2017 after astronomers spotted a distinct periodic light going on and off like a candle from its host star eac...
