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 par.....»»
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.....»»

Can quantum particles mimic gravitational waves?
When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (L.....»»
Study reveals soliton solutions in Maxwell-Bloch systems
Dr. Asela Abeya, of SUNY Poly faculty in the Department of Mathematics and Physics, has collaborated with peers at the University at Buffalo and Rensselaer Polytechnic Institute on a research paper titled "On Maxwell-Bloch systems with inhomogeneous.....»»
Experiment uses quantum techniques to stimulate photons, enhancing search for dark matter
Scientists cannot observe dark matter directly, so to "see" it, they look for signals that it has interacted with other matter by creating a visible photon. However, signals from dark matter are incredibly weak. If scientists can make a particle dete.....»»
NASA, JAXA bounce laser beam between moon"s surface and lunar orbit
NASA's LRO (Lunar Reconnaissance Orbiter) has twice transmitted a laser pulse to a cookie-sized retroreflector aboard JAXA's (Japan Aerospace Exploration Agency) SLIM lander on the moon and received a return signal......»»
Unlocking carbon"s potential: CRISPR boosts lignocellulose absorption
Lignocellulosic biomass, such as paper mulberry, holds promise for sustainable material production due to its cost-effectiveness and renewability. However, optimizing lignin composition remains challenging due to its complex structure and varied comp.....»»
Astronomers find first emission spectra in brightest GRB of all time
Chance that first detected emission line is a noise fluctuation is one in half a billion. Enlarge / A jet of particles moving at nearly light-speed emerges from a massive star in this artist’s concept of the BOAT. (credit: NASA.....»»
Save your data on printable magnetic devices? New laser technique"s twist might make this reality
The proliferation of all things digital doesn't mean that printing technology is no longer relevant. In fact, printing technology is required to make the semiconductors necessary for the digital world. And as an Osaka Metropolitan University-led team.....»»
