Clever Technology Decodes More Information From Single Photons
2014-02-12 21:17:46

National Institute of Standards and Technology (NIST) It's not quite Star Trek communications—yet. But long-distance communications in space may be easier now that researchers at the National Institute of Standards and Technology (NIST) and Jet Propulsion Laboratory (JPL) have designed a clever detector array that can extract more information than usual from single particles of light. Described in a new paper, the NIST/JPL array-on-a-chip easily identifies the position of the exact...

Superconductor Astronomy

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...

Satellites Providing Information On Earth’s Albedo With Remarkable Accuracy
2013-09-06 11:48:30

[ Watch The Video - Reflecting Power Of Earth’s Albedo ] ESA The amount of sunlight being absorbed or reflected by Earth is one of the driving forces for weather and climate. Satellites are providing this information with unprecedented accuracy. The reflecting power of a surface is known as ‘albedo’. Bright snow and ice have a high albedo, meaning they reflect solar radiation back into space, while green areas like forests and fields have a much lower albedo. The lower the...

Seasat Blazed The Trail For Many Mission
2013-06-28 05:27:14

April Flowers for redOrbit.com - Your Universe Online Even if they don't last long, history tends to look fondly upon trailblazers. Thirty-five years ago this week, NASA's Jet Propulsion Laboratory (JPL) launched an experimental satellite called Seasat, with the mission to study Earth and its seas. An unexpected malfunction ended the mission after just 106 days, leading some to look on the satellite as a failure. Seasat is still in orbit, however, shining in the night sky at magnitude...

A remarkable ESA campaign in one of the remotest regions on Earth has been fundamental in ensuring that the SMOS mission is delivering reliable data to improve our understanding of Earth´s water cycle. The two-year campaign set out to answer a simple but important question: do the microwave signals of a particular wavelength emitted from the surface the Antarctic ice shelf towards the SMOS satellite change over time? For a satellite mission that maps variations in soil...

The bolometer, invented in 1878 by Samuel Pierpont Langley, measures the energy of incident electromagnetic radiation. It consists of an absorptive element connected to a heat sink through a thermal link. The absortive element raises its temperature above that of the heat sink when radiation impinges on it. The higher the energy the higher the temperature rises. Old bolometers used metals while newer ones used semiconductors and superconductors as the absorptive elements. Bolometers can...
