WISE Catalog And Atlas Just Got Wiser
2013-11-16 04:55:07

April Flowers for redOrbit.com - Your Universe Online A new and improved atlas and catalog, brimming with data on three-quarters of a billion objects detected during two full scans of the sky, were released by NASA on Friday from their Wide-field Infrared Survey Explorer (WISE) mission. In 2010, WISE scanned the entire sky in infrared light, snapping a dozen pictures of every star and galaxy. The spacecraft ran out of the coolant needed to chill some of its heat-seeking detectors in...

Brett Smith for redOrbit.com - Your Universe Online Having been commercially manufactured since the 1960s, semiconductors are the backbone of modern electronics. However, these materials are slowly being replaced by superconductors – particularly in the field of astrophysics. Superconductivity is essentially a quantum phenomenon that happens when certain materials are cooled to near absolute zero. This cooling eliminates electrical resistance and magnetic fields, allowing for the...

Weather Balloon Helps Measure Earth's Reflectivity
2013-11-01 04:20:18

Lee Rannals for redOrbit.com - Your Universe Online The amount of sunlight reflecting off of Earth’s atmosphere is a key measurement for better understanding climate change, and weather balloons could help advance data collection techniques even more. NASA’s Earth Science Technology Office is supporting the development of the HyperSpectral Imager for Climate Science (HySICS). This instrument made its inaugural engineering balloon flight at the end of September, providing realistic,...

World’s Most Powerful Terahertz Quantum Cascade Laser Developed
2013-10-30 10:39:08

Vienna University of Technology Whether it is diagnostic imaging, analysis of unknown substances or ultrafast communication – terahertz radiation sources are becoming more and more important. At the Vienna University of Technology, an important breakthrough has been achieved. Terahertz waves are invisible, but incredibly useful; they can penetrate many materials which are opaque to visible light and they are perfect for detecting a variety of molecules. Terahertz radiation can be...

Seeing In The Dark With Novel Infrared Remote Sensing System
2013-10-29 14:33:32

American Institute of Physics Thermal infrared (IR) energy is emitted from all things that have a temperature greater than absolute zero. Human eyes, primarily sensitive to shorter wavelength visible light, are unable to detect or differentiate between the longer-wavelength thermal IR "signatures" given off both by living beings and inanimate objects. While mechanical detection of IR radiation has been possible since Samuel Pierpont Langley invented the bolometer in 1880, devices that also...

Star Formation -- Star formation is the process by which gas in molecular clouds gets transformed into stars. In the current paradigm of star formation, cores of molecular clouds (regions of specially high density) became gravitationally unstable, and start to concentrate. Part of the gravitational energy lost in the process is radiated in the infrared, another part increases the temperature of the core. The accretion of material happen partially though a circumstellar disc. When...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...

Word of the Day
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
