Bergeson, Ware, and Peatross recently published a null measurement of annual variations in nuclear decay rates. Although other researchers reported variations at the 0.1% level, the BYU team pushed that level down to 0.01%. In some cases, their data suggest an upper limit of 0.001% and they have plans for going further.
This is a mosaic of solar eclipse images secured on May 20, 2012 by Dr. Michael D. Joner. The individual observations were made between 6:59 and 8:06pm MDT a couple of miles northwest of Kanarraville, Utah on the center line of this annular solar eclipse. The entire solar photosphere was not blocked by the passage of the Moon for this eclipse. The result was an annular eclipse due to the fact that the Moon was close to apogee and thus not large enough in the sky to cover the entire Sun. Areas of southern Utah enjoyed perfect weather in addition to being ideally located to view the eclipse well before sunset.
University Photographer, Mark Philbrick, captured this sunset image of the BYU West Mountain Observatory in early June 2016. At the same time, Physics and Astronomy students were at work preparing the telescopes for yet another night of research observations. Data are secured on these nights for a wide variety of projects ranging from careful searches for exoplanets to monitoring active galaxies. The resulting data support research efforts of BYU students and faculty and in many cases contribute to larger international collaborations.
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.
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.

Lyrids in Southern Skies: Earth's annual Lyrid meteor shower peaked before dawn on April 22nd, as our fair planet plowed through dust from the tail of long-period comet Thatcher. Seen from the high, dark, and dry Atacama desert a waning crescent Moon and brilliant Venus join Lyrid meteor streaks in this composited view....
