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.

This year, in an annual trek to the Nevada desert, UW students deliberately launched rockets from altitude directly into a dry lakebed. These were early tests of a concept that eventually could be used to collect and return samples from an erupting volcano, a melting nuclear reactor or even an asteroid in space.
For the first time, scientists have direct geochemical evidence that the 150-mile long Tsangpo Gorge, possibly the world’s deepest, was the conduit by which megafloods from glacial lakes, perhaps half the volume of Lake Erie, drained catastrophically through the Himalayas when their ice dams failed during the last 2 million years.
A substance implicated in several mass extinctions could greatly enhance plant growth, with implications for global food supplies biofuels, new UW research shows.
In recent decades the thinning of glaciers at the edge of Antarctica has accelerated, but new UW-led research indicates the changes, though dramatic, cannot be confidently attributed to human-caused global warming.
Regional cloud changes may be as important for climate change as the overall amount of cloud cover.
Changes in the speed that ice travels in more than 200 outlet glaciers indicates that Greenland’s contribution to rising sea level in the 21st century might be significantly less than the upper limits some scientists thought possible, a new study shows.
