Galileo, the NASA space probe in which UK scientists have played a key role, will dramatically end its 14-year mission when it plunges into Jupiters dense atmosphere on the 21st September. The spacecraft, which has revealed a wealth of scientific data on Jupiter and its moons, with fuel and power exhausted, will vaporize like a meteor as its descends through the giant planets turbulent atmosphere (an artists impression of what this might look like is available - please see notes to editors).

As well as extensive scientific data, Galileo has provided the most visually stunning images of Jupiter and its moons ever, especially Io and Europa. The probe, launched in 1989 by the Space Shuttle Atlantis, also imaged the Earth, Venus, the Moon and several asteroids during its lifetime.
The highlights of the mission include the identification of massive amounts of lightening activity in Jupiters atmosphere, where hurricane-force winds and huge amounts of heat from the interior whip clouds of frozen ammonia into bands that encircle the planet, studded with giant storms, some of them larger than the entire Earth. The planet is richer in heavy elements than the Sun, showing that it was assembled from smaller planetesimals rather than condensing in isolation as previously surmised.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
