• The Goldilocks Core: Habitability from the Inside Out byAnnika Salmi| Feb 19, 2026 |Daily Paper Summaries|1 comment Title:The chemical habitability of Earth and rocky planets prescribed by core formation Authors:Craig R. • Rogers, Amy Bonsor, Rob Spaargaren, Oliver Shorttle & Maria Schönbächler First author’s institution:Institute of Particle Physics and Astrophysics, ETH Zürich and the Institute of Astronomy, University of Cambridge Status:Published in Nature Astronomy [openaccess] Scientists have often talked about looking for life on exoplanets by focusing on the habitable zone, or the “Goldilocks zone.” This is the area around a star where it’s not too hot and not too cold, so liquid water can exist. • In our Solar System, Earth is in this zone, while Venus is too hot and Mars is too cold. • Astronomers care about liquid water because all known life depends on it. • When a new exoplanet is discovered, scientists can estimate whether water could exist there. • Today,more than 6,000exoplanets have been found, andapproximately 70of them might have the right temperatures for liquid water.
