The Possibility of Life in the 'Terminator Zones' of Alien Planets
Tidally locked planets, with one side always facing their star, could be habitable in the twilight zone between eternal day and night. A team of researchers modeled the climate conditions on these planets and found that planets with a mix of water and dry land could sustain a temperate zone where liquid water and life as we know it could exist. These planets are likely to be common around M-type stars, which account for 70% of the stars in our cosmic neighborhood.
