... The Great Nebula in Carina . ... Eta Carinae , the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically. Eta Carinae is the brightest star near the image center, just left of the Keyhole Nebula . While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that much of the Great Carina Nebula has been a veritable supernova factory . Tomorrow's picture: open space . ...

Most of these images were obtained by Mike Bessell, Michelle Buxton, Hwankyung Sung, Ralph Sutherland and Bob Watson at SSO using a 2Kx2K Site CCD behind a Nikon or Hasselblad lens or directly on the 1m telescope. A few images are from the Hubble Space Telescope. Some of the M42 images were obtained with the KPNO 1m and ESO NTT telescope. One image is a mosaic of IRAS images. ...

... 2010 . ... The following images are mosaics obtained on 03 August 2010 at the National Solar Observatory/Dunn Solar Telescope with the Interferometric Bidimensional Spectrometer (IBIS). ... The final images are approximately 238 x 242 arcseconds, or 4 x 4 arcminutes, with a pixel scale of 0.0976 arcseconds per pixel. ... The images show a broad range of typical chromospheric structures, including sunspots, superpenumbra, plage, filaments, and quiet internetwork. ...

... V.R.I - the Virtual Radio Interferometer . ... The Virtual Radio Interferometer (V.R.I.) - a Java applet - allows users to explore the uv-coverage and FFT images resulting from different distributions of telescopes, including current radio interferometers such as ATCA, WSRT, Merlin, and ASKAP. The example above shows the combination of two ATCA configurations, EW352 (blue) and H168 (red), each observing a radio galaxy at DEC = -45 degr for 8 hours. ... today * ATNF | ... ATCA | ...

We have produced a high-level overview of PROS. ... The incremental stages were the short-term goals: a project overview diagram (i.e., an organizational diagram of software modules); high-level diagram (i.e., a bubble diagram of each module in the system); and unifying element tables (i.e., tables of task vs. software attributes)....

... The texture was formed in part by the bump map shown below. ... This is an example of how to render a realistic looking fabric, at fairly high detail. ... Bump maps are applied to a unit square. ... In my example I scaled this down to 0.17 (arbitrarily picked), which ammounts to 1/0.17 = 5.88 bump maps per unit, or 11.76 threads per unit. ... To match this to the bump map, it has to be scaled in half, so that we have two-by-two checker squares in each unit square, just like the bump map. ...
