Scientists Discover 7 Earth-Like Planets

February 22, 2017

Scientists announced today that they’ve found a cluster of planets 40 light-years away that could support life. There are seven Earth-sized planets orbiting around a small star/sun named TRAPPIST-1 and it is possible those planets have liquid water and forms of life — alien life. 

 

The planets are rocky, like Earth and are in the “Goldilocks zone” — which means that they are not too cold nor too hot (like Earth is). Now scientists are trying to detect signs of oxygen (which shows there are plants) or methane (which can come from microbes). 

 

Scientists plan to send out a new telescope in 2018 that will provide better measurements of the chemicals — such as ozone and carbon dioxide. It might take ten years before scientists will know if there is life or not, though. 

 

They say if you could stand on one of the planets, you would see a salmon-colored sun that is brighter than the moon but less bright than our sun. You would see various planets, twice the size of the moon, moving across the sky.

Wow… we’re closer and closer to Star Wars.
