In astronomy, background commonly refers to the incoming light from an apparently empty part of the night sky.. Even if no visible astronomical objects are present in given part of the sky, there always is some low luminosity present, due mostly to light diffusion from the atmosphere (diffusion of both incoming light from nearby sources, and of man-made Earth sources like cities).
Paranal Observatory nights. [3] The concept of noctcaelador tackles the aesthetic perception of the night sky.

Skyglow (or sky glow) is the diffuse luminance of the night sky, apart from discrete light sources such as the Moon and visible individual stars. It is a commonly noticed aspect of light pollution . While usually referring to luminance arising from artificial lighting , skyglow may also involve any scattered light seen at night, including ...
On 21 March 2013, the European-led research team behind the Planck cosmology probe released the mission's all-sky map (565x318 jpeg, 3600x1800 jpeg) of the cosmic microwave background. [ 46 ] [ 47 ] The map suggests the universe is slightly older than researchers expected.
Making It Enjoyable and Sustainable. As we age, a good night’s sleep becomes even more crucial for our overall health and well-being. However, maintaining consistent sleep patterns can become a ...
Sky brightness refers to the visual perception of the sky and how it scatters and diffuses light. The fact that the sky is not completely dark at night is easily visible. If light sources (e.g. the Moon and light pollution ) were removed from the night sky , only direct starlight would be visible.
