Scientists discover surprising importance of 'I Love Q' for understanding neutron stars

more »

Scientists can learn a tremendous amount about neutron stars and quark stars without understanding their internal structure in detail, according to two Montana State University scientists who published their findings in the July 26 issue of "Science."

NASA's IRIS telescope offers first glimpse of sun's mysterious atmosphere

more »

The moment when a telescope first opens its doors represents the culmination of years of work and planning -- while simultaneously laying the groundwork for a wealth of research and answers yet to come. It is a moment of excitement and perhaps even a little uncertainty. On July 17, 2013, the international team of scientists and engineers who supported and built NASA's Interface Region Imaging Spectrograph, or IRIS, all lived through that moment. As the spacecraft orbited around Earth, the door of the telescope opened to view the mysterious lowest layers of the sun's atmosphere and the results thus far are nothing short of amazing. The data is crisp and clear, showing unprecedented detail of this little-observed region.

NASA's Van Allen Probes discover particle accelerator in the heart of Earth’s radiation belts

more »

Scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe called the Van Allen radiation belts. Scientists knew that something in space accelerated particles in the radiation belts to more than 99 percent the speed of light but they didn't know what that something was. New results from NASA's Van Allen Probes now show that the acceleration energy comes from within the belts themselves. Particles inside the belts are sped up by local kicks of energy, buffeting the particles to ever faster speeds, much like a perfectly timed push on a moving swing.

Bad night's sleep? The moon could be to blame

more »

Many people complain about poor sleep around the full moon, and now a report offers some of the first convincing scientific evidence to suggest that this really is true. The findings add to evidence that humans -- despite the comforts of our civilized world -- still respond to the geophysical rhythms of the moon, driven by a circalunar clock.

NASA Mission Discovers Particle Accelerator in Heart of Van Allen Radiation Belts

Using data from a NASA satellite, scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe and known as the Van Allen radiation belts.

IRIS Mission Gets First Look at Sun's Mysterious Interface Region

NASA's Interface Region Imaging Spectrograph (IRIS) spacecraft has captured its first observations of a region of the sun that is now possible to observe in detail: the lowest layers of the sun's atmosphere.

In this Hubble Space Telescope composite image taken in April 2013, the sun-approaching Comet ISON floats against a seemingly infinite backdrop of numerous galaxies and a handful of foreground stars. The icy visitor, with its long gossamer tail, appears to be swimming like a tadpole through a deep pond of celestial wonders.

Physicists publish solution to the quantum measurement problem

more »

(Phys.org) —Quantum mechanics is a highly successful theory, but its interpretation has still not been settled. In their recent opus magnum, Theo Nieuwenhuizen (Institute of Physics, UvA) and colleagues claim to have found a solution to the so-called quantum measurement problem.

What if quantum physics worked on a macroscopic level?

more »

Quantum physics concerns a world of infinitely small things. But for years, researchers from the University of Geneva (UNIGE), Switzerland, have been attempting to observe the properties of quantum physics on a larger scale, even macroscopic. In January 2011, they managed to entangle crystals, therefore surpassing the atomic dimension. Now, Professor Nicolas Gisin's team has successfully entangled two optic fibers, populated by 500 photons. Unlike previous experiments which were carried out with the fiber optics of one photon, this new feat (which has been published in Nature Physics) begins to answer a fundamental question: can quantum properties survive on a macroscopic level?

'International beam team' solves Martian meteorite-age puzzle

more »

By directing energy beams at tiny crystals found in a Martian meteorite, geologists have proven that the most common group of meteorites from Mars is almost four billion years younger than many scientists had believed -- resolving a long-standing puzzle in Martian science and painting a much clearer picture of the Red Planet's evolution that can now be compared to that of habitable Earth.

(Phys.org) —New areas of extragalactic study may emerge from research by University of Alabama in Huntsville (UAH) astrophysicists using data from the Chandra X-ray Observatory to conclude that baryons making up all visible matter – once thought to be missing from clusters – are present in the expected ratios in large, luminous clusters.
