More small planets in the Habitable Zone of their stars confirmed!
This discovery is important because it shows that we don’t need to play “which exoplanet is the most Earth-like?” any more. Asking that question is really a guessing game with eyes closed, without having information from the atmosphere of the planet to let us see if there is water and other ingredients for life on that planet. All planets that are small enough to be rocky (about 1.6 to 1.8 Earth radii and smaller) and are within the Habitable Zone are very intriguing!
And we are finding a diversity of planets with these specs. Really exciting times to live in… getting closer to the question whether we are alone in the universe…
