      The Dark Energy Spectroscopic Instrument is under installation at the Mayall Telescope (top, center) at Kitt Peak National Observatory near Tucson, Arizona.

    For a special sneak preview before the official start of observations in early 2020, join scientists, engineers, and others who are working on the Dark Energy Spectroscopic Instrument (DESI) for an exclusive day of access. DESI, under installation at Kitt Peak National Observatory,  will capture the light from tens of millions of distant galaxies to better understand the accelerating expansion of the universe.

    This September 13 registration-required event for news media, limited to 20 people, will provide a look inside the 4-meter Mayall Telescope dome that houses DESI, and will highlight its unique capabilities and ambitious observing program.

    You will also have an opportunity to meet with DESI project participants to learn about the project and its aims. DESI will use an array of 5,000 automated, swiveling, robotic positioners, each carrying a fiber-optic cable, to individually gather the light from pre-selected space objects. This telescope will be used to assemble the largest 3-D map of the universe.

    DESI construction and installation is ongoing, and event participants will also learn about the next milestones toward project completion.

    Exclusive Tour for Media: Friday, September 13

    REGISTRATION

    To attend the event, please contact Glenn Roberts Jr. at geroberts@lbl.gov or Laurel Kellner at lkellner@lbl.gov for registration information. Please specify whether other members of your media team are also planning to attend this Media Day Event, and also if you’d like to request a one-on-one interview with a DESI scientist.

    Please indicate your interest by August 19.

    TRANSPORTATION

    The event will feature a safety briefing and a tour of the site and will last about 4 hours. Approved visitors must arrange their own transportation to the Kitt Peak National Observatory site.

    Kitt Peak National Observatory is about 53 miles from Tucson International Airport.

    Even Hard Materials Have Soft Spots

    Even Hard Materials Have Soft Spots

    The Achilles Heel of "metallic glasses" is that while they are strong materials--even stronger than conventional steels--they are also very brittle. The initial failures tend to be localized and catastrophic. This is due to their random amorphous (versus ordered crystalline) atomic structure. Computer simulations revealed that the structure is not completely random, however, and that there are some regions in the structure that are relatively weak. Defects nucleate more easily in these regions, which can lead to failure. This understanding of the mechanical properties has led to a strategy for making the material stronger and less brittle.

    2-D Atoms Do the Twist

    In the study, scientists demonstrated, for the first time, an intrinsically rotating form of motion for the atoms in a crystal.

Whether the rotation is clockwise or counter-clockwise depends on the wave's propagation direction.
