Rosettas Earth fly-by on 4 March, ESAs closest ever at just 1900 kilometres, will provide a fantastic photo opportunity. The Rosetta Up Close photo contest will recognize and reward the best images and sky watchers everywhere are invited to participate.
If youve got a decent amateur telescope and digital imaging equipment, you can probably take some impressive photos of Rosetta—weather permitting—as the craft speeds by Earth.
After sunset in Europe on Friday, 4 March, the spacecraft will appear to travel from south east to south west, moving from the constellation Sextans towards the setting Sun, crossing the complete sky. It will move faster as it heads west, disappearing below the horizon around 23:00 CET. As seen from Europe, it will only reach a magnitude of about +8 or +9 on the brightness scale used by astronomers; this is dimmer than a typical faint star and not readily apparent to the eye.

Quantum optical sensor for the first time tested in space – with a laser system from Berlin

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

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...
