During space-communication researchers require high-space intersatellite data transfer connectivity for deep-space missions while monitoring Earth. The technology is fundamentally influenced by available transmission power ...
Polish astronomers have detected a new ultracompact X-ray binary as part of the Optical Gravitational Lensing Experiment (OGLE). The newly found binary, designated OGLE-UCXB-01, is an unusual periodic variable object with ...
MIT researchers have developed a novel "photonic" chip that uses light instead of electricity—and consumes relatively little power in the process. The chip could be used to process massive neural networks millions of times ...
