Study lends support to prevailing model of Milky Way structure

Results from a new technique designed to map the structure of the Milky Way appear to support the four spiral arm model of our galaxy. A team of researchers from the Federal University of Rio Grande do Sul, Brazil, used data collected by NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft to pinpoint star clusters located in the resource rich environment of the spiral arms, and use them as markers to trace the structure of our galaxy.

NASA trains pilots with Fused Reality

To gain proficiency, pilots need realistic training, but they also need to avoid needless cost and risk. Real aircraft provide the most obviously realistic training, but they're dangerous in inexperienced hands. Meanwhile, simulators can reproduce much of the look and feel of actual flying without the danger of losing an aircraft or pilot, but they aren't as successful when it comes to complex maneuvers like aerial-refueling. To square the circle, NASA is developing a technology called Fused Reality, which uses a special headset that combines real flying in a real aircraft with an overlaid simulation.
