BYU’s very first physics graduate, known to many as the “Father of Stereophonic Sound,” is being recognized by the National Academy of Recording Arts and Sciences at this year’s Grammy Awards. The Recording Academy selected Dr. Harvey Fletcher to win a posthumous Technical Grammy Award for his work with Leopold Stokowski and the Philadelphia Orchestra, producing more than a hundred of the world’s first stereophonic recordings.
This picture shows the familiar winter constellation of Orion setting in the west as it moves behind the main dome at the BYU West Mountain Observatory. The constellation of Orion is filled with giant molecular clouds and current star forming regions. Even in this short exposure, the Orion nebula is clearly visible in the sword of Orion. This picture was taken by Professor Michael Joner while working at the observatory on a clear spring night.
Wave-like modulations with non-lattice periodicities accompany a variety of important physical phenomena (e.g. magnetism and superconductivity) and dramatically complicate any quantitative crystal-structure analysis. An exhaustive group-theoretical enumeration of the order parameters that can arise from 1D incommensurate modulations now make it much easier to characterize crystals that behave this way.

In this image of from BYU's x-ray diffraction facility, x-rays arriving from the left scatter in all directions from a tiny crystal at the center, and are then imaged by a 16-megapixel x-ray camera. The often beautiful scattering patterns that result contain a wealth of information about the atomic structure of the sample. The speed and sensitivity of state-of-the-art instruments like this have revolutionized the study of crystalline materials.
This is a photo taken in the early evening of September 27, 2015 showing the full moon rising over Y Mountain. This is the last of four total lunar eclipses that were visible during the two year period that began with an Easter eclipse in 2014. This cycle of four total lunar eclipses is known as a tetrad. It is relatively rare to have a cycle such as this coincide with religious holidays such as Easter and so these eclipses were frequently associated with "end of the world" speculation.
