American scientists continue to search for life forms on exoplanets in distant galaxies, so they decided to create a specialized catalog with a list of all terrestrial analogs that can be found in outer space. They are going to explore new forms to find analogs on celestial bodies.
In this guide, the planet is depicted in different forms, taking into account the dominant form of some organisms. Scientists are confident that if there are habitable worlds in the Universe, then such a base will allow a better understanding of how they look. Scientist Lisa Kalteneger from Cornell University noted the importance of such a development for space researchers. During a long historical stage in the formation of our planet, microbes were the first representatives of living organisms.
Exoplanets can go through identical evolutionary periods, so that the new data includes even extremophiles that can survive in the most difficult natural conditions. The theory does not work on Earth due to the huge variety of life forms, but on other planets with dominant species, it can be applied in practice. So far, scientists have studied 137 species of organisms on our planet.
