Cassini data obtained during a close flyby of the Saturn moon Enceladus support an observation that large amounts of water are spewing into space from the tiny moons surface. This water originates near south polar "hot spots" on the moon, possible locations for the development of primitive life in the solar system.
Announced by the Cassini Imaging Science Team in todays issue of Science, the theory is bolstered by measurements from the Cassini Plasma Spectrometer (CAPS), as reported in the same issue by a team led by Robert Tokar of Los Alamos National Laboratory. CAPS was partly designed and built at Los Alamos.
"During the July 14 close flyby we began getting signatures, far from Enceladus, of water ejection. From the deflections we could measure of the ionized gas in the magnetosphere, it was erupting at 100 kg per second (220 lbs per second), and the data are consistent with measurements from the spacecrafts other instruments. It is actual H20 molecules," said Tokar.

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...
