The spectrum of the Sun's solar radiation is close to that of a black body with a temperature of about 5,800 K. The Sun emits EM radiation across most of the electromagnetic spectrum.Although the Sun produces gamma rays as a result of the nuclear-fusion process, internal absorption and thermalization convert these super-high-energy photons to lower-energy photons before they reach the Sun's

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. The sky's brightness varies greatly over the day

We said that astronomers use absolute brightness, which is the apparent brightness stars would have if they were all at the same distance of 10 parsecs. The diagram above uses apparent brightness (apparent magnitudes), but for stars all at the same distance (the distance to the Pleiades star cluster), so it is really a plot of absolute brightness versus color.

3/11/2018 · Other Factors to Consider When Determining Brightness Other factors to consider that affect the brightness of a light bulb include the optics, lens, reflectors and the fixture itself. An optic sits on top of the bulb’s lens to control the beam of light and can restrict some of the light coming through thereby dulling the bulb’s brightness.
