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.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
