Zone d'habitabilité

Not long ago, Ramses Ramirez (Earth-Life Science Institute, Tokyo) described his latest work on habitable zones to Centauri Dreams readers. Our own Alex Tolley (University of California) now focuses on Dr. Ramirez’ quest for ‘a more comprehensive habitable zone,’ examining classical notions of worlds that could support life, how they have changed over time, and how we can broaden current models. We can see ways, for example, to extend the range of habitable zones at both their outer and inner edges. A look at our assumptions and the dangers implicit in the term ‘Earth-like’ should give us caution as we interpret the new exoplanet detections coming soon through space- and ground-based instruments.
