If there was a competition of stunning views, TRPPIST-1e would win hands down. Situated 40 light-years from Earth, TRAPPIST-1e displays objects in a red sky, which look like the moon. In fact, they are Earth-sized planets. The fourth from the TRAPPIST-1 star, happens to be the habitable zone, as here, liquid water is most likely to be detected.
