Because of strong city lights, light pollution is a challenge to all night star gazers. Light pollution obscures the stars, interferes with astronomical observatories, and, like any other form of pollution, disrupts ecosystems and has adverse health effects. Around most of the globe, sky watchers go to great lengths to find perfectly dark skies, where the dimmer lights can be seen with the naked eye. Such us the case of the Namibian desert.

The Milky Way appears like a band because it is a disk-shaped structure being viewed from inside. The fact that this faint band of light is made up of stars was proven in 1610 when Galileo Galilei used his telescope to resolve it into individual stars. In the 1920s, observations by astronomer Edwin Hubble showed that the Milky Way is just one of many galaxies.
