As well as keeping their fingers crossed for good weather during next weeks close approach of Mars, astronomers are hoping that the skies will be clear on Mars itself.
During National Astronomy Week - Saturday 23 to Saturday 30 August - observing events will be held across the UK where the public can view Mars through telescopes. It is expected that thousands of people will turn out to see the planet closer than it has been for almost 60,000 years. But its not just our own familiar clouds that could spoil the view. There is a risk that a major dust storm on Mars could wipe out any of the surface details visible on the planet.
Marss orbit round the Sun is not circular, and its distance from the Sun varies by over 20 per cent. So when it is close to the Sun, as it is now, the additional solar heating can whip up dust storms that can cover huge areas. The most severe can cover the entire planet. This happened in 1971, for instance, just as the US Mariner 9 space probe arrived at the planet. Its cameras revealed a barren disc, with no detail at all. Marss atmosphere was filled with fine dust from pole to pole. Observers on Earth confirmed that no details could be seen for a whole month.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
