Asteroid Belt Provides New Clues to Tumultuous Past of the Solar System

Our solar system seems like a neat and orderly place, with small, rocky worlds near the Sun and big, gaseous worlds farther out, all eight planets following orbital paths unchanged since they formed.

Stellar Nursery Brewing in the Trifid Nebula

A storm of stars is brewing in the Trifid nebula, as seen in this view from NASA's Wide-field Infrared Survey Explorer, or WISE. The stellar nursery, where baby stars are bursting into being, is the yellow-and-orange object dominating the picture. Yellow bars in the nebula appear to cut a cavity into three sections, hence the name Trifid nebula.

ESO's Very Large Telescope Helps Create Weather Map of Brown Dwarf

ESO's Very Large Telescope has been used to create the first ever map of the weather on the surface of the nearest brown dwarf to Earth. An international team has made a chart of the dark and light features on WISE J104915.57-531906.1B, which is informally known as Luhman 16B and is one of two recently discovered brown dwarfs forming a pair only six light-years from the Sun. The new results are being published in the 30 January 2014 issue of the journal Nature.

New Map Charts Size, Composition, and Location of More Than 100,000 Asteroids

To get an idea of how the early solar system may have formed, scientists often look to asteroids. These relics of rock and dust represent what today's planets may have been before they differentiated into bodies of core, mantle, and crust.

Potentially Harder Tests Needed for Quantifying Quantum Speedup

Texas A&M University physicist Helmut G. Katzgraber's research takes him to the crossroads of physics, computer science, quantum information theory and statistical mechanics. For more than a decade, he has been pushing the frontiers of computational physics to study hard optimization problems and disordered materials, applying his expertise to problems in the fascinating and fast-evolving field of quantum computing.

New Ultra-Miniaturized Quantum Cascade Laser Products from Block Engineering

Block Engineering, the leader in Quantum Cascade Laser (QCL) instrumentation, announced today the release of two ultra-miniaturized QCL products, the Mini-QCL (TM) Module and the new LaserTune (TM) Infrared Source. The Mini-QCL is a widely-tunable QCL module for Original Equipment Manufacturers (OEMs), weighing only 75 grams (~2.5 oz). Block's next-generation LaserTune has been miniaturized to a compact (16.5 × 12.7 × 11 cm), wirelessly-controllable system, while offering the widest contiguous tuning range available on the market (greater than 1000 cm-1).

Ferromagnetism Switching Inspires Future Applications in Low-Power Spintronics

Scientists from Paris, Newcastle and Helmholtz-Zentrum Berlin have been able to switch on and off robust ferromagnetism close to room temperature by using low electric fields. Their results are inspiring for future applications in low-power spintronics, for instance, in fast, efficient and nonvolatile data storage technologies.

Researchers Study How Spin-Orbit Interaction Causes Anti-Parallel Spin States to Interact

In a recent publication B. Slomski and co-workers have been able to follow how spin-orbit interaction causes anti-prallel spin states to interact. The resulting spin flip yields an unexpected spin texture.

Swift's Ultraviolet/Optical Telescope Captures SN 2014J Supernova

An exceptionally close stellar explosion discovered on Jan. 21 has become the focus of observatories around and above the globe, including several NASA spacecraft. The blast, designated SN 2014J, occurred in the galaxy M82 and lies only about 12 million light-years away. This makes it the nearest optical supernova in two decades and potentially the closest type Ia supernova to occur during the life of currently operating space missions.

Researchers Create Quantum Dots Containing Single Cobalt Ions

New types of solotronic structures, including the world's first quantum dots containing single cobalt ions, have been created and studied at the Faculty of Physics at the University of Warsaw. The materials and elements used to form these structures allow us forecast new trends in solotronics – a field of experimental electronics and spintronics of the future, based on operations occurring on a single-atom level.
