A new planet near the habitable zone around a bright cool star. Scientists report the existence of 15 new planets – including one ‘super-Earth’ that could harbor liquid water – orbiting small, cool stars near our solar system. These stars, known as red dwarfs, are of enormous interest for studies of planetary formation and evolution. One of the brightest red dwarfs, K2-155 that is around 200 light years away from Earth, has 3 transiting super-Earths, which are slightly bigger than our own planet. Of those 3 super-Earths, the outermost planet, K2-155d, with a radius 1...
