Superalloys are high-performance materials that are essential to key transportation and power generation technologies. By using BYU's supercomputer as a virtual lab, together with state-of-the-art algorithms for modeling materials, the Materials Simulation Group (msg.byu.edu) has identified 75 new superalloy candidates for which there are no reported phase diagrams. The new candidates may be the key to enhanced performance in transportation and power generation components. The figure shows the computed formation enthalpy over more than 700 Ni-based systems that were explored as part of this large survey. Roughly speaking, the darker the circle, the more promising the system. The x-y coordinates in the grid denote the two minority elements that are combined with nickel.
On April 18, 2018 the NASA TESS satellite was launched. This will be a two year survey mission that focuses on finding exoplanets around the brightest stars of the night time sky. TESS should find planets that range from Earth size up to Gas Giants. To prepare for the launch of TESS BYU astronomers have been developing telescope facilities, over a wide range of apertures, to provide follow-up observations of exoplanet candidates . In particular, funding was received from the Utah NASA Space Grant Consortium to develop five robotic telescope systems on the observation deck of the Eyring Science Center.
On April 18, 2018 the NASA Transiting Exoplanet Survey Satellite (TESS) was launched. TESS is on a two year survey mission that focuses on finding Earth-sized exoplanets. The TESS survey will examine about 85% of the total sky and include about 20 million stars. Among these targets will be a majority of the closest and brightest stars in the visible nighttime sky. TESS is expected to find thousands of planets that range from Earth size up to Gas Giants. To prepare for the launch of TESS, BYU astronomers have been developing robotic telescope facilities with a wide range of apertures to provide follow-up observations of the many new exoplanet candidates. Funding for these efforts was received from the Utah NASA Space Grant Consortium to develop five robotic telescope systems on the newly renovated observation deck of the Eyring Science Center.

Grain boundaries are the interfaces between the small crystals that make up nearly every material in our physical world. Understanding grain boundaries is essential because they dictate the most important characteristics of a material. Want to make steel corrosion resistant? The key is in the grain boundaries because they are the pathways for corrosive elements. Scientists at BYU, in collaboration with a scientist at Cambridge (UK), recently developed a machine learning approach predicting grain boundary properties. Not only can it make predictions, but the design of the machine learning model also makes it explanatory---It can identify the "physics reason" why some grain boundaries are good, and some are bad.
The small, northern constellation Triangulum harbors this magnificent face-on spiral galaxy, M33. Its popular names include the Pinwheel Galaxy or just the Triangulum Galaxy. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way. About 3 million light-years from the Milky Way, M33 is itself thought to be a satellite of the Andromeda Galaxy and astronomers in these two galaxies would likely have spectacular views of each other's grand spiral star systems. As for the view from planet Earth, this sharp composite image, a 25 panel mosaic, nicely shows off M33's blue star clusters and pinkish star forming regions that trace the galaxy's loosely wound spiral arms. In fact, the cavernous NGC 604 is the brightest star forming region, seen here at about the 1 o'clock position from the galaxy center. Like M31, M33's population of well-measured variable stars have helped make this nearby spiral a cosmic yardstick for establishing the distance scale of the Universe.
