Observations of the bright side of the Moon with NASAs Chandra X-ray Observatory have detected oxygen, magnesium, aluminum and silicon over a large area of the lunar surface. The abundance and distribution of those elements will help to determine how the Moon was formed.
The Moon: Lunar prospecting with NASAs Chandra X-ray Observatory
“We see X-rays from these elements directly, independent of assumptions about the mineralogy and other complications,” said Jeremy Drake of the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass, at a press conference at the “Four Years with Chandra” symposium in Huntsville, Alabama.
"We have Moon samples from the six widely-space Apollo landing sites, but remote sensing with Chandra can cover a much wider area,” continued Drake. “Its the next best thing to being there, and it’s very fast and cost-effective.”

Vortex photons from electrons in circular motion

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
