Does this make your head hurt? Oct 17, 2009
Microwaves, which are effectively light with a very long wavelength, are a practical way to transport electrical power. It is also possible to turn electricity into light, using a laser, and then reverse the process at the other end. (BBC News -- UK)
Scientists make first discovery using revolutionary long wavelength demonstrator array Aug 19, 2009
Standing next to a prototype of one of the anticipated 13,000 Long Wavelength Array dipole antennas are (left to right) Brian Hicks, Jake Hartman, and Paul Ray of the NRL.. (Washington, DC 08/18/09) Scientists from NRL's Space Science and Remote Sensing Divisions, in collaboration with researchers from the University of New Mexico (UNM) and the National Radio Astronomy Observatory (NRAO) located in Socorro, N.M., have generated the first scientific results from the Long Wavelength...

Betelgeuse, Red Supergiant In Constellation Orion, Has Shrunk By 15 Percent In 15 Years Jun 17, 2009
"We observe around 11 microns, the mid-infrared, where this long wavelength penetrates the dust and the narrow bandwidth avoids any spectral lines, and so we see the star relatively undistorted," said Townes. "We have also had the good fortune to have an instrument that has operated in a very similar manner for some 15 years, providing a long and consistent series of measurements that no one else has. The first measurements showed a size quite close to Michelson's result, but over 15 years, it... (Science Daily)

Red light has a long wavelength and blue has the shortest. When the light passes through the atmosphere, the light is scattered by the air molecules. (Chetek Alert, WI)
NRL part of multi-national team that launches Herschel Space Observatory May 15, 2009
The Herschel Space Observatory is a successor to several earlier small cryogenic observatories that covered parts of the terahertz range, including ESA's Infrared Space Observatory (ISO), on which NRL scientists were co-investigators on the Long Wavelength Spectrometer, and NASA's Spitzer Space Telescope, a mission whose cryogens are now depleted. Both hosted small superfluid-helium cooled telescopes, 0. (EurekAlert! -- Business News)
