NASA scientists identified detailed atmosphere of a midsize planet for the 1st time

For the first time ever, scientists have identified the detailed atmosphere of a midsize planet. The size of the planet is between the size of Earth and the Neptune. Even though such planets are common around other stars, such planets cannot be found in our solar system. Even though it is 318 times bigger than Earth, its atmosphere is majorly unpolluted. From a planet formation perspective, this is a big discovery.
