Astronomers solve temperature mystery of planetary atmospheres

An atmospheric peculiarity the Earth shares with Jupiter, Saturn, Uranus and Neptune is likely common to billions of planets, University of Washington astronomers have found, and knowing that may help in the search for potentially habitable worlds.

Study: Greenhouse gas might have warmed early Mars enough to allow liquid water

The mystery of how the surface of Mars, long dead and dry, could have flowed with water billions of years ago may have been solved by research that included a University of Washington astronomer.

Planetary ‘runaway greenhouse’ more easily triggered, research shows

It might be easier than previously thought for a planet to overheat into the uninhabitable “runaway greenhouse” stage, according to new research.

A warmer planetary haven around cool stars, as ice warms rather than cools

In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction of a star’s light with ice and snow on the planet’s surface.
