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. ...

... For more distant stars we must use other techniques. ... Hence if we see a distant galaxy and can pick out any cepheids lying within it, we can calculate its distance. ... Here then is another method to gauge the size of the Universe and there are yet more. volume at high enough temperature a nuclear fusion reaction sweeps across the white dwarf's surface and eventually we will see a spectacularly bright new star (hence nova) in our skies. ...

... 2001 April 24 . NGC 2264: Stars, Dust, and Gas . ... Explanation: The nebula surrounding bright star S Mon is filled with dark dust and glowing gas. The strange shapes that haunt this star forming region originate from fine interstellar dust reacting in complex ways to the energetic light and hot gas being expelled by the young stars. ... The blue glow directly surrounding S Mon results from reflection , where neighboring dust reflects light from the bright star. ... About APOD | ...

... Observations of GRB afterglows with Russian-Turkish 1.5-m Telescope (RTT150) . ... During the first 5 hours of our observations the afterglow faded exactly as a power law with index -1.19+-0.01 in each of the BVRI Bessel filters. ... We observe no variability above the gradual fading with the upper limits 10-1% on time scales 0.1-1000s. Spectral flux distribution in four BVRI filters corresponds to the power law spectrum with spectral index = 0.66 +- 0.01. ...
