Rosettas goal is to unravel the origins of the Solar System
Comet Wirtanen as seen by the VLT
Chase a fast-moving comet, land on it and ’ride’ it while it speeds up towards the Sun: not the script of a science-fiction movie, but the very real task of ESA’s Rosetta spacecraft.
New observations with the European Southern Observatory’s (ESO) Very Large Telescope (VLT) provide vital information about Comet Wirtanen - Rosetta’s target - to help ESA reduce uncertainties in the mission, one of the most difficult ever to be performed.
Every 5.5 years Comet Wirtanen completes an orbit around the Sun. Wirtanen has been seen during almost all its apparitions ever since its discovery in 1948, but only recently have astronomers obtained detailed observations that have allowed them to estimate the comet’s size and behaviour. The most recent of these observations was performed in December 2001 with the Very Large Telescope (VLT), located at the Paranal Observatory (Chile). As a result of these observations ESA will be able to refine plans for its Rosetta mission.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
