Habitable worlds is a research area that focuses on the search for planets and moons in the universe that have the potential to support life as we know it. Scientists in this field study various factors that contribute to a planet's habitability, such as its distance from its host star, presence of water and other necessary elements for life, and suitability for the development of complex organisms. The search for habitable worlds involves the use of telescopes, space probes, and other advanced technologies to detect and study exoplanets that may have the conditions necessary for life to exist. This research area is crucial in our quest to understand our place in the universe and the likelihood of finding other habitable environments beyond Earth.
