Ken Moody, Chief Scientist for Radiochemistry, explains that recent discoveries of new elements have extended the periodic table beyond what was thought was possible, and demonstrates the existence of a collection of Superheavy Elements with unusual nuclear properties at the limits of stability. Explore the relationship between atoms and elements, and between nuclei and isotopes. Discover how new elements are produced and identified, and how this leads to experiments that tell us about the extreme limits of chemical behavior, the possible breakdown of periodicity, and the ultimate end of the periodic table.

Last year, using adaptive optics and the 10 meter W.M. Keck telescope in Hawaii, a Lawrence Livermore National Lab team produced the first ever picture of another solar system. One day, these techniques may even lead to an image with a pale blue dot circling a nearby star - another Earth. Join LLNL astronomer Bruce Macintosh and Lisa Poyneer as they describe the new technologies that made these pictures possible.
