This same performance will be achieved in higher winds when the telescope enclosure is facing away from the wind, or by using wind screens. ...

The project assumes creation of an international space observatory - the interferometer "Earth - Space - Space" in order to perform of astronomical investigations in millimeter, submillimeter and infrared regions with extremely high sensitivity (to a few nanoJanskies units of flux density in continuum spectrum) and extremely high angular resolution (to a parts of microsecond of arc or, possibly, nanosecond). ... radio-interferometric channels of the system "Space - Space", region 0.2 - 3 mm; . ...

. Bright Supernovae - 2006 . This data comes from IAU Circulars and occasionally more data will be provided on IAU 's Astronomical Headlines page. An archive of the 2006 updates to this page is available. This is a list of the supernovae discovered in 2006. For supernovae which are still visible, please look at the main page for the latest data. Note that Extra galactic Novae have been moved to a special Extra galactic novae page . For more information, you can look at the following Supernova Catalogs: .

An eight-billion-year-old cluster of stars 13,000 light-years from Earth, called NGC 6791, can be seen in the image. ... This particular cluster is called an open cluster, because the stars are loosely bound and have started to spread out from each other. The area pictured is 0.2 percent of Kepler's full field of view, and shows hundreds of stars in the constellation Lyra. The image has been color-coded so that brighter stars appear white, and fainter stars, red. ...

... Aims: Today, large ground-based instruments, like VISIR on the VLT, providing diffraction-limited (about 0.3 arcsec) images in the mid-infrared where strong PAH features appear enable us to see the flaring structure of the disks around Herbig Ae stars. Although great progress has been made in modelling the disk with radiative transfer models able to reproduce the spectral energy distribution (SED) of Herbig Ae stars, the constraints brought by images have not been yet fully exploited. ...
