Dynamic Habitable Zones: Eccentric Orbits and Climate Variability on Exoplanets

To the point

Planets around other stars can have eccentric orbits that move them in and out of the star's habitable zone, so they might heat up and then freeze on the surface while life could survive underground, showing that habitability depends on orbital geometry and stellar radiation rather than a fixed boundary, and the image credit goes to NASA/JPL-Caltech with Diana Logreira named as the Responsible NASA Official for Science.
