Inside an early star-forming galaxy

U.S. astronomers from the California Institute of Technology (Caltech) have used adaptive optics (AO) on the 10-meter Keck Telescope in Hawaii in conjunction with other images provided by the Hubble Space Telescope to look inside a young star-forming galaxy as it appeared only two billion years after the Big Bang. The team made their observations by coupling two techniques, gravitational lensing and laser-assisted guide star (LGS) adaptive optics. 'Adaptive optics corrects the blurring effects of Earth's atmosphere by real-time monitoring of the signal from a natural guide star or an artificial guide star.' But read more...

Microshutters for the Webb Space Telescope

In case you don't remember, the Webb Space Telescope will replace Hubble, probably after 2011, and should be able to catch phenomena which happened 13.5 billion light-years ago. At these distances, the instruments onboard will need to be more precise than ever. This is why NASA has developed a new technology based on microshutters for a better focus of distant galaxies. These arrays of microshutters, composed of more than 62,000 individual shutters measuring 100 by 200 microns, will allow scientists to systematically block out light that they do not want, allowing the large-format detector to measure infrared spectra optimally.
