Carol Rasmussen, NASA Earth Science News Team After 14 years of monitoring Earth's main energy source, radiation from the sun, NASA’s Active Cavity Radiometer Irradiance Monitor satellite has lost contact with its ground operations team at NASA's Jet Propulsion Laboratory, Pasadena, California, and its mission has been declared completed. AcrimSat's ACRIM 3 instrument was the third in a series of satellite experiments that have contributed to a critical data set for understanding...

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...

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...

endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
