This technology was first used during the Arctic expedition of Ann Bancroft and Liv Arnesen, who were forced to cancel their voyage seven days in due to a combination of damaged gear, frostbite and extreme cold. Although they were unable to access the images because extremely low temperatures prevented them from switching on their computer, people at their base camp viewed the images and passed on the sea ice conditions to them by phone.
International Polar Year (IPY) is an internationally coordinated two-year effort in which more than 5000 scientists from 60 countries will conduct research in the Arctic and Antarctic to increase our knowledge of the polar regions, how they are changing and how those changes impact the health of our planet.
This IPY not only marks the first time satellites will be used to help guide expeditions but also the first time scientists will be armed with satellite measurements to better understand these regions, which play a vital role in the Earth's climate and ecosystems.
ESA will make significant contributions to IPY on a variety of scientific fronts. In addition to providing Earth observation data free of charge to 48 projects, the agency will co-lead a large IPY project – the Global Interagency IPY Polar Snapshot Year (GIIPSY) – with the Byrd Polar Research Centre. The goal of GIIPSY is to make the most efficient use of Earth-observing satellites to capture essential snapshots that will serve as benchmarks for gauging past and future changes in the environment of the polar regions.
This service was developed and is being operated by Kongsberg Satellite Services (KSAT), equally owned by the Norwegian Space Centre and Kongsberg Defence and Aerospace.

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,...
