<p>An astronaut orbiting Earth in the International Space Station has remotely directed a NASA rover in California to unfurl an “antenna film” that scientists at the �Ǹ�Թ� are developing for use on the unexplored far side of the moon.</p>

<p>The confidence of Colorado business leaders has continued its strong upward trend, surging into the third quarter of 2013, according to the most recent Leeds Business Confidence Index, or LBCI, released today by the �Ǹ�Թ�’s Leeds School of Business.</p>

<p>Waleed Abdalati has been named the new director of the Cooperative Institute for Research in Environmental Sciences, or CIRES, a joint institute of the �Ǹ�Թ� and the National Oceanic and Atmospheric Administration.</p>
<p>Abdalati is a CIRES Fellow, a CU-�Ǹ�Թ� professor of geography and director of the CIRES Earth Science and Observation Center. He will take office on July 1.</p>

<p>Let’s all fist bump: Spiral galaxies like our own Milky Way appear to be much larger and more massive than previously believed, according to a new �Ǹ�Թ� study by researchers using the Hubble Space Telescope.</p>

<p>The �Ǹ�Թ� has become a full institutional member of the Sloan Digital Sky Survey-IV, an ambitious effort by some of the world’s top astronomers to map the celestial sky in three dimensions to learn more about the structure and evolution of the universe.</p>

<p>The �Ǹ�Թ� has been chosen by the Association of American Universities to be one of eight campuses participating in a new initiative to improve undergraduate education in science, technology, engineering and math.</p>
<p>Over the next three years, each of the eight project sites will receive $500,000 to undertake an innovative STEM education project.</p>

<p>The Colorado River provides water for more than 30 million people in the U.S. West, so water managers have been eager to understand how climate change will affect the river’s flow. But scientific studies have produced an unsettling range of estimates, from a modest decrease of 6 percent by 2050 to a steep drop of 45 percent by then.</p>
