Researchers identify useful emission lines in the sun’s outer atmosphere

When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels. Emission spectra of two iron ions, Fe IX and Fe X, are particularly useful for studying the sun’s outer atmosphere. However, both of these spectra contain emission lines […]

Massive solar wind disturbance caused Earth’s magnetosphere to fly without its usual tail

Like a supersonic jet being blasted with high-speed winds, Earth is constantly being bombarded by a stream of charged particles from the sun known as solar wind.

First full 2-D spectral image of aurora borealis from a hyperspectral camera

Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission bands, and the color is determined by the transition energy levels, molecular vibrations and rotations.

Cold antimatter for quantum state-resolved precision measurements

Why does the universe contain matter and (virtually) no antimatter? The BASE international research collaboration at the European Organization for Nuclear Research (CERN) in Geneva, headed by Professor Dr. Stefan Ulmer from Heinrich Heine University Düsseldorf (HHU), has achieved an experimental breakthrough in this context.

Cosmic microwave background experiments could probe connection between cosmic inflation, particle physics

Various large-scale astrophysical research projects are set to take place over the next decade, several of which are so-called cosmic microwave background (CMB) experiments. These are large-scale scientific efforts aimed at detecting and studying CMB radiation, which is essentially thermal radiation originating from the early universe.

New ‘game-changing’ discovery for light-driven artificial intelligence

In a paper, titled “Partial coherence enhances parallelized photonic computing,” published in Nature, researchers from the University of Oxford, along with collaborators from the Universities of Muenster, Heidelberg, and Ghent, report that replacing lasers with less complex light sources can surprisingly boost performance in some optical applications, such as light-driven AI technologies.
