Spiral Light Waves Used For Future Optical Communication

Network communication is currently estimated to be very crowded, each network scrambling to transmit more data over limited bandwidth. When this type of light waves are being studied for use in solid tissue, called a spiral or optical vortex beams. Complex light waves with wave resembles a spiral that spins when sending data communication. Recently, physicists from the Harvard School of Engineering and Applied Sciences (SEAS) have created a new device that enables a conventional optical detector, which is usually only measure the intensity of light to capture the rotation. This device has the potential to increase the capacity of optical fiber...

Exomoon, Livable Zone Search Among the Exoplanets

Astronomers began to consider Exomoon or planets orbiting that allow the existence of life outside our solar system. In a new study, a pair of researchers have found that it is possible to support Exomoon life like exoplanet. Exomoon research conducted by Rene Heller of Germany's Leibniz Institute for Astrophysics Potsdam and Rory Barnes of the University of Washington, and the NASA Astrobiology Institute, the journal will be published in the January 2013 issue of Astrobiology. Approximately 850 exoplanets (planets outside our solar system) that was discovered and largely sterile gas giant similar to Jupiter. Only a few planets have solid surfaces...
