‘Would you like a little ice with your exoplanet?’ For Earth-like worlds, that may be a tall order

Scientists computationally simulated more than 200,000 hypothetical Earth-like worlds all in orbit of stars like our sun, and found that about 90% of these potentially habitable hypothetical worlds lacked partial surface ice like polar caps. When partial ice is present, ice belts — permanent surface ice along the equator — were more common than ice caps.
