Key partners include the University of Alabama at Huntsville, Smithsonian Astrophysical Observatory, University of Central Lancashire in Lancashire, England, and the Lebedev Physical Institute of the Russian Academy of Sciences.
Hi-C will image the Sun at a 5x higher resolution (0.1 arcsec/pixel image) than any previously done. The mission will demonstrate the technology necessary to collect 150-kilometer-resolution images of the sun in the extreme ultraviolet spectrum. Using a resolution 5 times greater than any previous imager, Hi-C will observe the small-scale processes that exist everywhere in hot magnetized coronal plasma. Above image is 0.5 arcsec/pixel.

Understanding the sun's activity and its effects on Earth's environment is the critical scientific objective of Hi-C, which will provide unique, unprecedented views of the dynamic activity in the solar atmosphere.
The telescope is slated for launch in July 2012. It will fly aboard a Black Brant sounding rocket to be launched from the White Sands Missile Range in New Mexico.
The mission will demonstrate the technology necessary to collect 150-kilometer-resolution images of the sun in the extreme ultraviolet spectrum. Using a resolution 5 times greater than any previous imager, Hi-C will observe the small-scale processes that exist everywhere in hot magnetized coronal plasma. Additionally, the mission is designed to study the mechanisms for growth, diffusion and reconnection of magnetic fields of the corona, and to help understand the coupling of small-scale dynamic and eruptive processes to large scale dynamics.
A major scientific impact of Hi-C will be to place significant new constraints on theories of coronal heating and structuring, by establishing whether or not there is additional fine structure below the current level of resolution.
"This instrument could push the limits on theories of coronal heating, answering questions such as why the temperature of the sun's corona is millions of degrees higher than that of the surface," said Marshall heliophysicist, Dr. Jonathan Cirtain, who is Principle Investigator, on the Hi-C mission.
"Hinode has shown that current instrumentation used for coronal structure studies has insufficient resolution to separate individual features along the line-of-sight," Cirtain said. "Hi-C will accomplish this measurement, with margin".For more information about NASA and agency programs, please visit: http://www.nasa.gov Janet Anderson

Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
