Night Sky Illumination (Light Pollution)

Night Sky Illumination (Light Pollution) – Increasingly, astronomical observations are hampered by light from artificial light sources superimposed on the night sky. Over the past hundred years, astronomical observatories that were built in or near cities have lost importance due to the development of the use of electricity to illuminate populated areas.
In areas that are economically developed, at night artificial light sources illuminating the atmosphere create the effect of “light pollution”, which in English means “light pollution”.
This phenomenon not only interferes with telescope observations in these regions, but also affects all of humanity. At the moment, a noticeable part of the world’s population lives in complete darkness of the starry sky, created by artificial illumination of the Earth’s atmosphere. There is a tendency that the regions where there is a strong “light pollution” are constantly expanding and more and more people end their life without seeing the starry sky.
Conditions are worsening with space objects and electromagnetic radiation being observed from Earth. There is a tendency to increase the frequency ranges, powers and number of different radiating radio devices that can interfere in the radio bands that astronomers are interested in.
