The scientific discoveries that concern outer space are surely fascinating to read since they excite the imagination for the unknown mysteries of cosmos, even to people that do not ardently follow the news and know the details related to them. I believe 2018 will be a truly fascinating year due to the launch of the JWST(James Webb Space Telescope) which will undoubtedly assist us to unravel many enigmas of the universe, since its penetrating gaze will be able among others to glimpse at the composition of the atmospheres surrounding many of the exoplanets you have mentioned and possibly give us clues about their potential for habitability. I believe the following years will be simply astounding!
