If you missed your chance to see the transit of Mercury on November 11, 2019, you will need to wait awhile to get another chance. While Venus transits are rare and occur about twice in a century, Mercury transits the Sun 14 times in this century. The next such event will occur on November 13, 2032. This three frame exposure shows Mercury (the tiny black dots) at three different positions during the last hour of the most recent transit. Also, it is noteworthy that there is a total absence of sunspots at this time as the Sun has been quiet for most of this year. These images were secured in Provo by Professor Michael Joner.
The phrase “Magnificent Desolation” was used by Apollo 11 Lunar Module Pilot Buzz Aldrin to describe his view shortly after he became the second person to step out onto the surface of the Moon on July 20, 1969. The photo shown here is centered on the relatively young crater Copernicus located just south of Mare Imbrium. This impact crater is 93 km in diameter and approximately 3.8 km deep. The rugged terrain seen here is a reminder of the magnificent desolation that is characteristic of our nearest neighbor in the solar system. This image was secured by Dr. Michael Joner using the 0.9-meter reflector operating at f/11 on site at the BYU West Mountain Observatory just after last quarter phase in early September 2018.
This demonstration illustrates the power of a wave focusing technique called time reversal acoustics. A vibration speaker and a laser Doppler vibrometer are used to knock over one targeted Lego figure among many placed on an aluminum plate. BYU researchers (Brian Anderson and students) use this technique to locate and characterize cracks in structures, to deliver private communications, and many other potential applications.

Carbon Nanotubes, in addition to having high strength and electron mobility, are being used as frameworks to fabricate high aspect ratio 3-D structures on the microscale creating devices with extreme versatility in shape and construction materials. These structures are being used for applications ranging from brain-machine interfaces to environmental and medical sensors.
Carbon nanotube templated microfabrication (CNT-M) was used to create structured materials with control over length scales from 10 nm to over 100 microns. The electron micrographs shows control over three dimensional microscale features that is possible with CNT-M (as seen in top left image). Nanoscale porosity is also controlled (seen in top right image) and when coupled with microscale patterning results in the fabrication of structures (bottom left) for high performance chemical separations (bottom right).
