Close binary stars cannot be resolved with today's optical telescopes, despite adaptive optics (AO) that remove the fuzziness caused by atmospheric turbulence. Now, an international team of astronomers has built and mounted on a 3-meter California telescope, a fibered optic imager that combines AO and interferometry. The imager will resolve for the first time, close binaries such as Capella. The team also mounted an improved imager on an 8-meter Subaru telescope. Full Story

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2020 budget of $8.3 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
