Five years after breaking ground on a South African mountaintop near the edge of the Kalahari desert, astronomers today (Sept. 1, 2005) released the first images captured by the Southern African Large Telescope (SALT), now the equal of the worlds largest optical telescope and a prized window to the night skies of the southern hemisphere.
With a 10- by 11-meter hexagonal segmented mirror and state-of-the-art scientific instrumentation, the new telescope was constructed by an international consortium of universities and government agencies. Partners include the National Research Foundation of South Africa, the University of Wisconsin-Madisons College of Letters and Science, Polands Nicolas Copernicus Astronomical Centre and Rutgers University, among others.
The new $18 million observatory will provide unprecedented access to the astronomically rich skies of the southern hemisphere. Objects such as the Large and Small Magellanic Clouds, the galaxies nearest to our own Milky Way, will come into sharp view through the concerted focus of the 91 hexagonal mirror segments that comprise the SALT Telescopes primary mirror array.

NASA keeps watch over space explosions

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
