The Discovery: Scientists have verified the existence of a super-Earth planet named HD 20794 d orbiting a star similar to our sun, located 20 light years away. This rocky planet, with a mass six times that of Earth, travels through the habitable zone of its star, where liquid water could potentially exist.
Significance: The planet's distinctive elliptical orbit leads to the freezing and thawing of water as it transitions between warm and cold regions, making it an ideal candidate for investigating the possibility of extraterrestrial life using advanced telescopes in the future.
