A team of researchers from the California Institute of Technology in Pasadena, CA, Yale University in New Haven, CT, and Gemini Observatory in Hilo, HI, report the discovery of a new planet in the outer solar system. Officially designated 2003 UB313, the new planet is intrinsically brighter than Pluto and three times farther away. Assuming the reflectivity of the surface is the same as Plutos, it is the largest object detected in the solar system since the discovery of Neptune and its moon Triton in 1846.
The discovery team consists of Michael Brown at Caltech, David Rabinowitz at Yale, and Chad Trujillo at the Gemini Observatory. This is the same team that a year ago announced their discovery of Sedna, a smaller body also at the distant edges of our solar system. The team has since discovered several other Pluto-scale bodies including 2005 FY9 and 2003 EL61, both objects in the outer solar system comparable in size to Pluto but smaller. 2003 EL61 was independently discovered by Spanish astronomers and reported today.
All of the new discoveries have been made with the Palomar QUEST camera, a gigantic digital camera built at Yale University and mounted on the 48-inch-diameter telescope at the Palomar Observatory in California. With this camera, observers can search the entire northern sky multiple times with greater sensitivity than any other telescope in the world. The Palomar Quest camera is currently being used by researchers at Yale, Caltech, and the University of California at Berkeley to search not only for new planets, but also for supernovae, distant galaxies, and variable stars.

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...
