Inside the Langley Research Center’s 4- by- 22 Foot Subsonic Tunnel, test engineer Samantha O’Flaherty completes setting up a model of QueSST, the Quiet Supersonic Technology.

Over the next several weeks, engineers will conduct aerodynamic tests on the 15% scale model and the data collected will be used to predict how the vehicle will. The QueSST Preliminary Design is the initial design stage of our planned Low-Boom Flight Demonstration experimental airplane, otherwise known as an X-plane. This is one of a series of potential future X-plane, one of the goals of which is to reduce fuel use, emissions and noise through innovations in aircraft design that depart from the conventional tube-and-wing aircraft shape.

This edge-on view of a galaxy located about 45 million light-years away, showcases its beautiful arms, which swirl like a whirlpool around its bright central region.

Astronomers took this image as they were observing an extraordinary exploding star – a supernova – near the galaxy’s central yellow core! The star rapidly evolved from a supernova containing very little hydrogen to one that is hydrogen-rich — in just one year. This rarely observed metamorphosis was luminous at high energies and provides unique insight into the poorly understood final phases of massive stars. By studying similar galaxies we hold a scientific mirror up to our own, allowing us to build a better understanding of our galactic environment, which we cannot always observe, and of galactic behavior and evolution as a whole.
