In astronomy and astrobiology, the habitable zone is the range of orbits around a star in which a planet can support liquid water.This habitable zone is also known as the ‘Goldilocks’ zone, taken from the children’s fairy tale.The temperature from the star needs to be ‘just right’ so that liquid water can exist on the surface.The boundaries of the habitable zone are critical.If a planet is too close to its star, it will experience a runaway greenhouse gas effect, like Venus.But if it’s too far, any water will freeze, as is seen on Mars.Since the concept was first presented in 1953, many stars have been shown to have a Goldilocks area, and some of them have one or several planets in this zone, like ‘Kepler-186f’, discovered in 2014.
