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

An artistic rendering showing an exoplanet with polar ice caps.

A team at the University of Washington and the University of Bern has computationally simulated more than 200,000 hypothetical Earth-like worlds all in orbit of stars like our sun. As they report in a paper accepted to the Planetary Science Journal and submitted Dec. 6 to the preprint site arXiv, on these simulated exoplanets, one common feature of present-day Earth was often lacking: partial ice coverage. About 90% of these potentially habitable hypothetical worlds lacked partial surface ice like polar caps.

A University of Washington-led team has revisited and comprehensively reinterpreted the radio telescope observations underlying a widely reported 2019 claim that phosphine gas was present in the atmosphere of Venus. In a paper accepted to the Astrophysical Journal, they report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.
