At a distance of just over four light years, Proxima Centauri is our nearest stellar neighbor and is known to be a very active M dwarf star. Its flare activity has been well-known to astronomers using ...
Traditional solar cells harvest only a narrow sliver of the electromagnetic energy pouring down onto Earth, and that's one of the reasons it's been so challenging to get solar efficiency beyond 20-30 ...
Using a heat-resistant device, made of tungsten and alumina layers, researchers have found that the device can absorb the sun's broad spectrum radiation and convert it to electricity. The photovoltaic ...
Scientists have discovered an indicator of when re-ionization of the primordial Universe began. The team used the Faint Object Camera and Spectrograph (FOCAS) mounted on the Subaru Telescope to ...
A research team, led by Professor Tomonori Totani (School of Science, the University of Tokyo) and composed of scientists from the National Astronomical Observatory of Japan, the Tokyo Institute of ...
How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...
Optically pumped semiconductor laser technology enables scaling of output power and wavelength throughout the visible and near-infrared regions of the spectrum. Matthias Schulze and Andrew Masters of ...
