... Deep optical CCD image of the LMC. Diffuse Galactic Light is plainly visible in this optical image of the Large Magellanic Cloud as a haze over the entire galaxy. The phenomenon arises from starlight scattering off numerous dust clouds in and above the plane of the LMC's disk to form a faint, galaxy-wide reflection nebula. ... The CCD image above was presumably taken with a special wide-field camera at optical wavelengths. ...

... The light baffles consist of the wind baffle that surrounds the telescope and doubles as a light baffle, the primary baffle that extends from the primary center-hole toward the secondary (left), the secondary baffle that extends from the perimeter of the secondary toward the primary (right), and the conical baffle that is suspended approximately halfway between the primary and secondary (middle). The wind baffle is covered with panels that are 25% porous to the wind. ...

Villains and Heroes of Lights and Lighting Fixtures . If we are to reduce the effects of light pollution, we must learn about the types, both good and bad, of fixtures used in outdoor lighting. ... In fact, this type of fixture is often chosen for this very reason. ... Although these lamps are not very energy efficient, and they are often found in older, inefficient fixtures that enhance light pollution, they still exist in great abundance in most locations and are still sold by the millions. ...

Such a model can reproduce much of the observed late-time evolution of the radio flux density and spectral index (though recent results for SNб 1993J (van Dyk et al. 1994) show that the Chevalier model does not adequately describe the early behaviour of radio light curves for this supernova, perhaps due to variations in the mass-loss rate and clumping in the stellar wind, which are not yet accounted for in the model). ...
