Project marks unique collaboration with NASA
NASA’s Far Ultraviolet Spectroscopic Explorer (FUSE) satellite will reach a major milestone on Thursday, June 24, 2004 – the five-year anniversary of its launch atop a Delta-II rocket from Cape Canaveral in Florida.
The 18-foot tall, 3,000 pound satellite continues to operate from its perch nearly 500 miles above the Earth’s surface, gathering unique data about everything from planets and nearby stars to galaxies and quasars billions of light years away. Groundbreaking science done during FUSE’s five years in orbit include a first-ever observation of molecular nitrogen outside our solar system; confirmation of a hot gas halo surrounding the Milky Way galaxy; and a rare glimpse into molecular hydrogen in the Mars’ atmosphere, among other findings. By its fifth anniversary, FUSE will have collected more than 47 million seconds of science data on more than 2,200 unique objects in the cosmos.

The surprising environment of an enigmatic neutron star

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
Scientists have succeeded in observing the first long-distance transfer of information in a magnetic group of materials known as antiferromagnets.
An international team of researchers has mapped Nemo's genome, providing the research community with an invaluable resource to decode the response of fish to...
Graphene is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand times faster than today’s silicon-based electronics. Scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) and the University of Duisburg-Essen (UDE), in cooperation with the Max Planck Institute for Polymer Research (MPI-P), have now shown for the first time that graphene can actually convert electronic signals with frequencies in the gigahertz range – which correspond to today’s clock rates – extremely efficiently into signals with several times higher frequency. The researchers present their results in the scientific journal “Nature”.
Graphene – an ultrathin material consisting of a single layer of interlinked carbon atoms – is considered a promising candidate for the nanoelectronics of the...
