ESA’s Venus Express mission will be the first spacecraft in more than 10 years to visit our nearest planetary neighbour. To celebrate a new phase of exploration of Earth’s sister world, the Planetary Society has teamed with ESA to invite youths and adults worldwide to enter the Venus Express Art Contest for a chance to win a trip to mission control in Darmstadt, Germany when Venus Express arrives at its destination in April 2006.
Venus, shrouded under a dense haze, is a world steeped in mystery. Often called our sister planet, Venus is nearly identical in size and mass, yet its surface temperature is hotter than a kitchen oven because the thick atmosphere traps the Sun’s heat. Instruments on board Venus Express will study the planet’s atmosphere and see what drives the planet’s high-speed winds. An on-board camera will capture images of the surface by peering through ‘windows’ in the enveloping haze.
The theme of Venus Express Art Contest is ‘Postcards from Venus.’ Contest entrants are invited to imagine the surface of Venus from an above-ground perspective – a bird’s eye view of a mysterious world whose volcano-riddled surface contains few impact craters, indicating a planet where resurfacing on a global scale has taken place within the last 500 million years.

Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
