Astronomers measure far-off galaxies to 1 percent precision

University of Washington astronomers and colleagues have measured the distance to galaxies six billion light-years away — about halfway back to the Big Bang — to an accuracy of just 1 percent.

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.

Can life emerge on planets around cooling stars?

UW astronomers find that planets orbiting white and brown dwarfs are unlikely to be good candidates for sustaining life.
