Satellite Mission Puts Einstein to the Test

March 5, 2015 | by Heidelberg University | News | Comments

Researchers have gained new insights into dark energy and the theory of gravitation by analyzing data from the “Planck” satellite mission of the European Space Agency. Their results demonstrate that the standard model of cosmology remains an excellent description of the universe. Yet when the Planck data is combined with other astronomical observations, several deviations emerge.

Distant Supernova Split Four Ways by Gravitational Lens

Over the past several decades, astronomers have come to realize that the sky is filled with magnifying glasses that allow the study of very distant and faint objects barely visible with even the largest telescopes. An astronomer has now found that one of these lenses – called an “Einstein cross”– has created four separate images of a distant supernova.

ESA’s Proba-V minisatellite captures the rare sight of standing water in the arid south Australian outback. Lake Frome, one of the whitest salt lakes in the southern hemisphere is visible to the right. Unusually, this 12 February image shows it filled with brackish water that has flowed down the creeks in the area, which are typically dry.

In 1976 several elongated comet-like objects were discovered on pictures taken with the UK Schmidt Telescope in Australia. Because of their appearance, they became known as cometary globules even though they have nothing in common with comets. The object shown in this new picture, CG4, which is also sometimes referred to as God’s Hand, is one of these cometary globules.

Designing the Building Blocks of Future Nano-computing Technologies

March 4, 2015 12:38 pm | by NSF | News | Comments

A relentless global effort to shrink transistors has made computers continually faster, cheaper and smaller over the last 40 years. This effort has enabled chipmakers to double the number of transistors on a chip roughly every 18 months — a trend referred to as Moore's Law. In the process, the U.S. semiconductor industry has become one of the nation's largest export industries, valued at more than $65 billion a year.

Fantastic 3-D Images of Intact Infectious Virus Revealed

For the first time, researchers have produced a 3-D image revealing part of the inner structure of an intact, infectious virus, using a unique X-ray laser. The virus, called Mimivirus, is in a curious class of “giant viruses” discovered just over a decade ago. The experiment establishes a new technique for reconstructing the 3-D structure of many types of biological samples from a series of X-ray laser snapshots.

Taming Magnetic Vortices: A Unified Theory for Skyrmion-materials

In the future, magnetic vortex structures — so-called skyrmions — have the potential to store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, physicists have succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and have developed a unified theoretical description of their behavior.

Meteorologists sometimes struggle to accurately predict the weather here on Earth, but now we can find out how cloudy it is on planets outside our solar system. MIT Researchers describe a technique that analyzes data from NASA’s Kepler space observatory to determine the types of clouds on planets that orbit other stars. Their models indicate that the clouds on Kepler-7b are most likely made from liquid rock.
