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.....»»

New technique detects THC in saliva in minutes with minimal sample
With just a few drops of saliva and in a few minutes the presence of THC can be detected thanks to a technique developed by the universities of Cordoba and Valencia, making it possible to accelerate the analysis process and to use very small samples.....»»
3D printing method reveals light emission from nanowires for the first time
Dr. Jaeyeon Pyo's team at the Korea Electrotechnology Research Institute (KERI) has become the first in the world to reveal light emission patterns from 3D-printed nanowires, which has been published as a cover article in the journal ACS Nano......»»
Organic polymer blend microspheres exhibit ultra-low threshold lasing with highest reported quality factor
Researchers at IMDEA Nanociencia have fabricated high quality microspheres from conjugated organic polymer blends with excellent lasing properties. The laser emission of the microspheres has the highest quality factor reported to date, Q>18,000......»»
Early riser: The sun is already starting its next solar cycle—despite being halfway through its current one
The first rumblings of the sun's next 11-year solar cycle have been detected in sound waves inside our home star—even though it is only halfway through its current one......»»
Observations detect a nearby hypervelocity stellar/substellar object
Using the Keck II telescope, astronomers have detected an object that may be a brown dwarf or a low-mass star, exhibiting a very high radial velocity. The object, designated CWISE J124909.08+362116.0 is located some 400 light years away. The finding.....»»
Researchers reveal parsec-scale radio emission properties of dual AGNs by multi-phase-center VLBI observations
Galaxy mergers play a crucial role in the cosmological evolution of galaxies. During galaxy merging, tidal torques can trigger the accretion and feedback of the central black holes in merging galaxies, forming dual active galactic nuclei (AGNs)......»»
Astronomers detect dozens of new pulsating white dwarfs
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected 32 new bright pulsating DA white dwarfs of the ZZ Ceti subclass. The finding was reported in a research paper published July 9 on the pre-print server arXiv......»»
How astronomers are using pulsars to observe evidence of dark matter
Tantalizing evidence of potential dark matter objects has been detected with the help of the universe's "timekeepers." These pulsars—neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space—were us.....»»
