UNIVERSE TODAY - Mars holds a special place in the Solar System. It represents marginal habitability. This means it transitioned from warm and wet and potentially hospitable, to cold and dry and inhospitable.
What can its transition tell us about exoplanet habitability?
New research to be published in the Planetary Science Journal examines the question. It's titled "Mars as an Exoplanet: Lessons from a Planet at the Edge of Habitability." The lead author is Stephen Kane, Professor of Planetary Astrophysics in the Earth & Planetary Sciences Dept. at the University of California, Riverside. The research is currently available at arxiv.org.
