Outside Earth's protective magnetic field and atmosphere, the ionizing radiation in space will pose a serious risk to astronauts as they travel to Mars….
With their remarkable electrical and optical properties, along with biocompatibility, photostability and chemical stability, gold nanoclusters are gaining a…
Speaking at the Goldschmidt conference in Paris where he is presenting the methods to be adopted, Dr Ken Williford (who is also Director of the Jet Propulsion…
Scientists working on ESA's Mars Express were looking forward to investigating the effects of the close encounter of Comet Siding Spring on the Red Planet's…
Hall thrusters (HTs) are used in earth-orbiting satellites, and also show promise to propel robotic spacecraft long distances, such as from Earth to Mars. The…
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are…
When the Moon moves in front of the Sun on Aug. 21, it will completely obscure the Sun's bright face. This happens because of a celestial coincidence – though…
Until now, researchers' understanding has been splintered at best, with mutually incompatible interpretations of the physical processes underlying the…
Because scientists had so many instruments observing the event, they were able to track the entire event from beginning to end, and explain for the first time…
Quantum mechanics describes how matter behaves on the smallest mass and length scales. However, the absence of quantum phenomena in our daily lives has…
Investigators at the University of Colorado, Boulder and the National Institute of Standards and Technology (NIST) have developed a new sensor array-based…
But the total solar eclipse will also have imperceptible effects, such as the sudden loss of extreme ultraviolet radiation from the Sun, which generates the…
Only a small part of the universe consists of visible matter. By far the largest part is invisible and consists of dark matter and dark energy. Very little is…
A visit to the optometrist often involves optical coherence tomography. This imaging process uses infrared radiation to penetrate the layers of the retina and…
Magnetism is a phenomenon that we experience in everyday-life quite often. The property, which is observed in materials such as such as iron, is caused by the…
Swansea University scientists working at CERN have again made a landmark finding, taking them one step closer to answering the question of why matter exists…
