Super-Earth discovered: Data will characterize planetary atmosphere models

During the past 25 years astronomers have discovered a wide variety of exoplanets, made of rock, ice and gas, thanks to the construction of astronomical instruments designed specifically for planet searches. Also, using a combination of different observing techniques they have been able to determine a large number of masses, sizes, and hence densities of the planets, which helps them to estimate their internal composition and raises the number of planets which have been discovered outside the So...
