... Following the Observatory's initiative in 2002, drawing attention locally to the issue of light pollution and the problems it produces both for astronomy and awareness of the night sky, and for saving energy and improving the natural environment, Mark Bailey made a presentation on light pollution, on 7 May 2003, to the Armagh City and District Council Environment, Health and Recreation Committee. This focused specifically on the growing problem of light pollution in the City of Armagh. ...

... This plug-in enables you to add various types of lighting effects to your (RGB) image. ... Directional light . ... Well, you get the idea :) The default settings for this light-type is [-0.5,-0.5,-1.0]. ... Higher values makes your image reflect a lot of light (appear lighter or more intense), while smaller values makes it appear more dull or matte. ... A value of 1.0 makes your image very shiny (bright high-lights) while smaller values makes you image less shiny, making the high-lights dimmer. ...

... Свет: остановка по требованию? ... Более мощное "управляющее поле" (свет с правой циркулярной поляризацией) делает возможным распространение в среде на порядок более слабого "сигнального поля" (упоминавшийся выше импульс, свет с левой циркулярной поляризацией), скорость распространения "сигнального импульса" при этом существенно уменьшается. ... Когда часть импульса (I) уже покинула кювету, управляющее поле выключают и из кюветы ничего не выходит до тех пор, пока управляющее поле не включат вновь. ...

... The Zodiacal light seen above the western horтАж . Sidebar Left . ... Title: The Zodiacal light seen above the western horizon nearly two hours after sunset . Description: It is produced by light scattered from interplanetary dust near the plane of rotation of the planets around the Sun. ... The Zodiacal light seen above the western horizon nearly two hours after sunset It is produced by light scattered from interplanetary dust near the plane of rotation of the planets around the Sun. ...

In version 1 of the data reduction, our approach to dealing with scattered light is the following: . For F814W we reject all frames with visible scattered light. ... Most of that will be recoverable with careful subtraction of the X pattern. For F606W we reject all the frames with visible scattered light. ... For F300W use all the data, but produce two versions of the drizzled image, one with the scattered light pattern, and the other with the scattered light pattern removed. ...

Tired light models invoke a gradual energy loss by photons as they travel through the cosmos to produce the redshift-distance law. ... The tired light model can not produce a blackbody spectrum for the Cosmic Microwave Background without some incredible coincidences. ... So the CMB must have come from a far away part of the Universe, and its photons will thus lose energy by the tired light effect. ... Assume that the CMB starts out as a T = (1+z)*T_o = 2.998 K blackbody, which is the blue curve. ...
