Visitors look at a model of a Saturn V rocket and its launch umbilical tower, which were used during the Apollo moon-landing program, at the Smithsonian National Air and Space Museum in Washington, D.C. Fifty years ago this July 20, Neil Armstrong and Buzz Aldrin became the first humans to walk on the moon.

In Klein tunneling, a negatively charged electron (brightly colored sphere) can transit perfectly through a barrier. In a new experiment, researchers observed the Klein tunneling of electrons into a special kind of superconductor. As electrons tunneled through the barrier, they each picked up a partner, doubling the conductance measured in the experiment. To balance out the extra negatively charged electron, a positively charged hole (dark sphere) is reflected back from the barrier--a process known as Andreev reflection.

C.L. Holloway in his atomic-recording studio. The stereo recording of Queen's 'Under Pressure' with an atom-based receiver shows the simultaneous detection of the vocal and instrumental part of a song by two atomic species. This illustrates that the atom receiver can receive multi-path communication signals simultaneously. Credit: J. Burrus at NIST

This image represents a deep dataset of the Coma galaxy cluster obtained by NASA's Chandra X-ray Observatory. Researchers have used these data to study how the hot gas in the cluster behaves. One intriguing and important aspect to study is how much viscosity, or "stickiness," the hot gas demonstrates in these cosmic giants. Credit: X-ray: NASA/CXC/Univ. of Chicago, I.
