NASA balloon mission captures electric blue clouds

On the cusp of our atmosphere live a thin group of seasonal electric blue clouds. Forming 50 miles above the poles in summer, these clouds are known as noctilucent clouds or polar mesospheric clouds—PMCs. A recent NASA ...

Collapsible wings help birds cope with turbulence

Collapsible wings may be a bird's answer to turbulence according to an Oxford University study in which an eagle carried its own 'black box' flight recorder on its back.

Astronomers take sharpest photos ever of the night sky (Update)

Astronomers at the University of Arizona, the Arcetri Observatory near Florence, Italy and the Carnegie Observatory have developed a new type of camera that allows scientists to take sharper images of the night sky than ever ...

Innovation in spectroscopy could improve greenhouse gas detection

(Phys.org) —Detecting greenhouse gases in the atmosphere could soon become far easier with the help of an innovative technique developed by a team at the National Institute of Standards and Technology (NIST), where scientists ...

Turbulent flows in 2D can be calculated in new model

Turbulent flows have challenged researchers for centuries. It is impossible to predict chaotic weather more than a week in advance. Wind resistance on a plane or a car cannot be calculated precisely, since it is determined ...
