Chunks May Have Split Off From Nucleus of Comet ISON

One or more chunks could have split off from the nucleus of comet ISON in recent days. Two wing-like structures in the gaseous environment of the comet, which have been photographed by a team of scientists from the Max Planck Institute for Solar System Research and the Wendelstein Observatory of the Ludwig Maximilian Universität Munich, seem to indicate this; the structures appear on images which were taken at the end of last week. This detachment of individual pieces of debris could possible explain the comet’s recent increase in brightness.

New Study Contributes Towards Computation with Individual Atoms

Advances in technology for computation and information storage always require to make the systems smaller and faster. The limits of miniaturization are those set by nature: Materials are composed by specific units, the atoms, that cannot be further divided.

Motion of Billions of Electrons within Astrophysical Plasma Jets Simulated Using ORNL TITAN Supercomputer

"When the wind blows over the ocean, waves form," Michael Bussmann, head of a HZDR junior research group, starts to explain. "At high wind speeds, water and wind swirl about one another, which is how spray and froth arise. Spray is thus a turbulent mixture of water and air. A similar thing occurs in space when a star ejects hot gas.

‘Cosmic Ray Telescope for the Effects of Radiation’ Detector Provides Hazard Data on Space-Based Radiation

Scientists from the University of New Hampshire and colleagues have published comprehensive findings on space-based radiation as measured by a UNH-led detector aboard NASA's Lunar Reconnaissance Orbiter (LRO). The data provide critical information on the radiation hazards that will be faced by astronauts on extended missions to deep space such as those to Mars.

Harvard-Smithsonian CfA Releases New Images of ISON

Hopes are high for Comet ISON, which has the potential to become the most spectacular comet seen in years. ISON is speeding through the inner solar system at about 120,000 miles per hour, on its way to a close approach to the Sun on November 28th. Assuming it survives its close encounter, it could become easily visible to the unaided eye in dawn skies.

Berkeley Lab Researchers Step Closer to Understanding Superconductivity

whereby certain materials can conduct electricity without any loss of energy – has proved to be one of the most persistent problems in modern physics. Scientists have struggled for decades to develop a cohesive theory of superconductivity, largely spurred by the game-changing prospect of creating a superconductor that works at room temperature, but it has proved to be a tremendous tangle of complex physics.

Closer to Achieving One Bit Per Atom Storage

One bit per atom: This would be the favourite principle for building the magnetic data storage devices of the future. A team including researchers from Karlsruhe Institute of Technology (KIT), the Max Planck Institute of Microstructure Physics in Halle and the University of Leipzig has now come much closer to achieving this.

Singlet Fission Holds Promise for Improved Solar Cells

Solar cells offer the opportunity to harvest abundant, renewable energy. Although the highest energy light occurs in the ultraviolet and visible spectrum, most solar energy is in the infrared.

Novel Device Leaves Photon Untouched Upon Detection

Light is of fundamental importance. It allows us to see the world around us and record pictures of our environment. It enables communication over long distances through optical fibers. All current methods of detecting light share a common property: absorption and thus destruction of a photon. It has been a long-standing dream to be able to watch individual photons fly by without absorbing them.

Hubble Space Telescope Captures Amazing Image of Messier 15 Globular Cluster

The NASA/ESA Hubble Space Telescope has captured the best ever image of the globular cluster Messier 15, a gathering of very old stars that orbits the centre of the Milky Way. This glittering cluster contains over 100 000 stars, and could also hide a rare type of black hole at its centre.

More-Distant Galaxy, With Strong Radio Emission Found Behind UGC 10288

Astronomers studying gas halos around nearby galaxies were surprised when detailed studies with the National Science Foundation's Karl G. Jansky Very Large Array (VLA) showed that one of their subjects is not a single galaxy, but rather two, nearly perfectly superimposed on the sky to masquerade as one. The discovery allowed them to use the alignment to learn otherwise-unobtainable facts about the nearer galaxy.
