Astronomers say they have for the first time spotted a planet beyond our own in what is sometimes called the Goldilocks zone for life: Not too hot, not too cold. Just right. Not too far from its star, not too close. So it could contain liquid water. The planet itself is neither too big nor too small for the proper surface, gravity and atmosphere. It's just right. Just like Earth. "This really is the first Goldilocks planet," said co-discoverer R. Paul Butler of the Carnegie Institution of Washington.
Now that we have explored Earth, Venus and Mars in some detail, it is very tempting to conclude that Venus is too close to the Sun so it is too hot for life as we know it. Mars is too far away from the Sun so it is too cold, and, as the Goldilocks fairytale goes, Earth is just the right distance from our Sun, neither too hot nor too cold to support life.This is the essence of the concept of the Goldilocks Zone, a specific distance from a star in which a planet receives just enough energy to support liquid water on its surface.
Goldilocks zone is the zone where earth lies. it is the zone where the temperature is just right it is not too cold not too hot it is just perfect to support life.
