The search for habitable planets is one of the most exciting aspects of modern astronomy. Scientists are looking for planets that exist in the “habitable zone” of their star, where conditions might allow liquid water to exist. These planets, known as exoplanets, are often discovered using telescopes like Kepler and TESS, which can detect their size, composition, and distance from their star.
As of today, thousands of exoplanets have been discovered, with some showing potential signs of habitability. Planets like Proxima b and Kepler-22b are prime candidates for further study, as they orbit within the habitable zone of their stars. These discoveries provide hope that life beyond Earth may be possible.
