New Submillimeter Image Reveals Glowing Stellar Nurseries

Submillimeter astronomy used to be known as the last unexplored wavelength frontier. But this new image from the Atacama Pathfinder Experiment (APEX) telescope reveals the awesome power of submillimetre-wavelength astronomy, and shows another new frontier: a birthplace of new stars. An expanding bubble of ionized gas about ten light-years across is causing the surrounding material to collapse into dense clumps, creating new stars. Submillimetre light is the key to revealing some of the coldest material in the Universe, such as these cold, dense clouds.

New image reveals glowing stellar nurseries

Illustrating the power of sub-millimeter-wavelength astronomy, an Atacama Pathfinder Experiment (APEX) telescope image reveals how an expanding bubble of ionized gas about 10 light-years across causes the surrounding material to collapse into dense clumps that are the birthplaces of new stars. Sub-millimeter light is the key to revealing some of the coldest material in the universe, such as these cold, dense clouds.

Organic dyes bring increased solar power

Particle physicists have long been familiar with the idea of shifting the wavelength of light to make detection easier – now the same idea could prove a boon for solar power. Michael Currie and colleagues from the Massachusetts Institute of Technology have shown that planar waveguides with a thin film of organic coating on one side and solar cells on the edges can produce significantly more power than the solar cells on their own.

Orange develops new part of Russian backbone

Orange Business Services has launched the Moscow-Samara section of its Russian backbone network. Based on DWDM (Dense Wavelength Division Multiplexing) technology, the 1,800 km network interconnects Moscow, Ryazan, Ulyanovsk and Samara. Penza and Tambov will be connected to the network by the end of the year.

Cassini Images Bizarre Hexagon on Saturn

This nighttime view of Saturn's north pole shows a bizarre six-sided hexagon feature encircling the entire north pole. The red color indicates the amount of 5-micron wavelength radiation, or heat, generated in the warm interior of Saturn that escapes the planet. Image credit: NASA/JPL/University of Arizona

Submillimeter Astronomy Enhances Stellar Formation Study

A new press release from the European Organization for Astronomical Research in the Southern Hemisphere (ESO, an inter-governmental institution involving 13 member states) shows the importance of the submillimeter astronomy field. Focusing on the formation of new stars within a studied region of space, it demonstrates that this technique, once regarded as the edge of wavelength measurements, has a crucial potential for understanding the universe.

Goldilocks, X-rays, and Nanotechnology

X-rays - electromagnetic radiation with wavelengths that are typically of the order of 0.05 nm to 1 nm - are finding growing importance in nanoscale measurement technology and metrology. Their sub-nanometer wavelengths and their typical weak interactions with solids make X-ray probes a nearly ideal way of studying the structural characteristics of thin layer and nanoscaled structures that underlie much of modern nanotechnology. The fact that the probing wavelength is commensurate with the sizes of nanostructured objects results in interactions (in particular, scattering processes) that occur over practically measureable length and angular scales.

Color E-Paper Debuts on Waterproof MP3 Player

E-ink and e-paper are the display buzzwords of the moment, but generally the devices are mono colored... until now. And though KDDI showed a concept color e-paper display recently, it looks like the first device to market sporting a colored e-paper display will be an MP3 player from Freestyle Audio. Qualcomm have come up with the paper, and it works by having multiple layers in the display: light is partially reflected at each layer, and due to wavelength filtering and interference between the light the colors are generated. Choice of color is achieved by varying the distance between the layers electrostatically. Clever stuff indeed...and of course it's instantly got us wondering about the possibilities for the Kindle 3.

Seeing With Your Skin?

Iddo Genuth writes to tell us that a researcher from Tel Aviv University is exploring the possibility that humans may be able to "see" via their skin. Professor Leonid Yaroslavsky hopes to utilize this possible technology to find solutions for the blind in addition to new types of image capture that might be able to work where conventional lenses fail. Unfortunately he has a long uphill battle ahead to convince others that his theories are possible. "The lenses currently used for optics-based imaging have many problems. They only work within a limited range of electromagnetic radiation. Relatively, these are still costly devices greatly limited by weight and field of view. The imaging Professor Yaroslavsky has in mind has no lenses and he believes the devices can be adapted to any kind of radiation and wavelength.
