ExoMars Trace Gas orbiter spots daylight green oxygen at Mars

This animated video shows six finely tuned lasers used inside NASA's Cold Atom Lab to slow down atoms, lowering their temperature. This is step one in a three-step cooling process.

Tiny sand grains trigger massive glacial surges

A new technique developed by Berkeley Lab researchers pairs high-resolution images derived by satellite with advanced computer modeling to estimate aquifer volume change from observed ground deformation. The method could be particularly helpful to managing groundwater resources in drought-prone agricultural regions such as California’s Central Valley.

Global air pollution maps now available

Larger than the planet Mercury, huge moon Titan is seen here as it orbits Saturn. Below Titan are the shadows cast by Saturn's rings. This natural color view was created by combining six images captured by NASA's Cassini spacecraft on May 6, 2012.
