Rare Space Experiment Gives Clues About the Fundamental Structure of the Universe
In this illustration, one photon (purple) carries a million times the energy of another (yellow). Some theorists predict travel delays for higher-energy photons, which interact more strongly with the proposed frothy nature of space-time. Yet Fermi data on two photons from a gamma-ray burst fail to show this effect, eliminating some approaches to a new theory of gravity. Credit: NASA/Sanoma State University/Aurore Simonnet
Blast from the Past Gives Clues About Early Universe
The NRAO's Very Large Array (VLA) telescope is located on the Plains of San Agustin, about 80 kilometers west of the Array Operations Center in Socorro, New Mexico.

The cartridge holds a "plug-plate" at the top, which positions a thousand optical fibers (red and blue). These cartridges are locked into the base of the telescope and are changed many times during a night.
