NASA's GRAIL Creates Most Accurate Moon Gravity Map
The variations in the lunar gravity field as measured by NASA's Gravity Recovery and Interior Laboratory (GRAIL) during the primary mapping mission from March to May 2012. Very precise microwave measurements between two spacecraft, named Ebb and Flow, were used to map gravity with high precision and high spatial resolution.

Tiny compound semiconductor transistor could challenge silicon’s dominance --MIT researchers develop the smallest indium gallium arsenide transistor ever built
A cross-section transmission electron micrograph of the fabricated transistor. The central inverted V is the gate. The two molybdenum contacts on either side are the source and drain of the transistor. The channel is the indium gallium arsenide light color layer under the source, drain and gate.

Fermi Improves its Vision for Thunderstorm Gamma-Ray Flashes
This photograph, taken in May 2008 as the Fermi Gamma-ray Space Telescope was being readied for launch, highlights the detectors of the spacecraft's Gamma-ray Burst Monitor (GBM). The GBM is an array of 14 crystal detectors designed for transient lower-energy gamma-ray outbursts, such as TGFs.
