The beginning of September 1859 was the occasion of the first and unique observation of a giant solar white light flare, auroral displays were observed at low latitudes and geomagnetic observatories recorded exceptional storms. This paper reviews the impact of the event on the earth system with a special emphasis on living processes using the historical(More)
The European AstRoMap project (supported by the European Commission Seventh Framework Programme) surveyed the state of the art of astrobiology in Europe and beyond and produced the first European roadmap for astrobiology research. In the context of this roadmap, astrobiology is understood as the study of the origin, evolution, and distribution of life in(More)
This paper describes the Space Control Centres use case of the CUBIST FP7 project 3. It introduces the concept of telemetry and describes the format and the contents of the housekeeping telemetry of SOLAR, one of the payloads flying on board of the International Space Station (ISS). Further on, it discusses several approaches to conceptual analysis of space(More)

in the rest of the disk. The correlation remains notable even if we do not apply a thickness filter to the data or if we use another definition of the thickness (3, 11). The two maps are not independent, however; changing the density distribution in the arms will necessarily produce changes in the measured thickness unless the perturbations are distributed(More)
We report what we believe to be the first simulation of enhanced backscattering (EBS) of light by numerically solving Maxwell's equations without heuristic approximations. Our simulation employs the pseudospectral time-domain (PSTD) technique, which we have previously shown enables essentially exact numerical solutions of Maxwell's equations for light(More)
