... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth. During a recent investigation by an international group of astronomers [1], the best picture ever of Pluto and Charon [2] was secured with the European Space Agency's Faint Object Camera at the Hubble Space Telescope (HST). ... The new HST image was taken when Charon was near its maximum elongation from Pluto (0.9 arcseconds). ...

... Infrared observations of RCBs show that, even at maximum light, there are copious amounts of dust surrounding the star ([ Kilkenny & Whittet 1984 ], [ Walker 1985 ]). A very interesting result is that during a decline, when the V-band brightness is plummeting, the infrared L-band brightness shows no significant change and continues to show pulsational variations [ Feast et al. ... Therefore the obscuring dust can only cover a fraction of the stellar surface. ...

In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

The picture above was made with this demo POV file and this hand shower object POV file . This is three objects: a hand shower head, a wall mount bar, and a connecting hose. This is one of my least detailed objects; there's not even a clip to mount the hand shower to the sliding bar, it just floats. The hand shower itself does look pretty stylish, very rounded and cool looking. ... The showerhead is about yay big. ... WARNING: This POV object is based on a real object. ...

The near-IR data from 2MASS (Two Micron All Sky Survey) and DENIS (Deep Near-Infrared Southern Sky Survey) are ideally suited for studies of the structure of the LMC, because of the large statistics and insensitivity to dust absorption. ...
