Exoplanets from TRAPPIST-1 system could contain water

“Just” 40 light-years from Earth is located the planetary system TRAPPIST-1 which contains seven Earth-like planets (in size and temperature). Until recently there was not much information about the intriguing planets, but now further information has been obtained from telescopes on the ground and from NASA's Spitzer Space Telescope and the Kepler Space Telescope. Most interestingly, the planets seem to contain water, some of them even more than our planet! Moreover, the planets are so close that they interfere with each other’s gravity. The TRAPPIST-1 system continues to be of interest for scientists due to the large agglomeration of exoplanets that might harbor life.
