habitable

University of California, Irvine astronomers have identified an exoplanet located within a star's habitable zone, a region where temperatures could allow liquid water to exist on the surface.

And reports from young men who have managed to sneak into Nur Shams suggest that Nehaya's house is no longer habitable.

"They are fingerprints of Earth's earliest history. If we can understand why they exist, we can understand how our planet formed and why it became habitable."

A planet's habitability is often tied to whether it falls within its star's 'habitable zone', where liquid water can persist on the surface of a planet with the right atmospheric conditions.

"The exoplanet is in the habitable or the 'Goldilocks Zone,' the right distance from its star that liquid water could exist on its surface, if it has the right atmosphere."
