Very low (virtually none) even though we use a little more power than that.

What is the abstract noun for the word - light?

The abstract noun for the word "light" is luminosity.


What is the luminosity of the night sky. How much light do the stars produce relative to us compared to the sun?

The luminosity of stars varies quite a bit. Most stars (about 85-90% of them) emit less light than our Sun, while a few very massive stars emit, in extreme cases, over a million times as much light (or more precisely: total radiation) than our Sun.

How do astronomers measure stellar luminosity?

The reference that astronomers use to compare the luminosity of other stars is the sun's luminosity. The luminosity is denoted in multiples of the sun's luminosity. For example, the luminosity of the star Sirius is 25 times the luminosity of the sun.


What percentage of energy does an energy saving bulb save compared to an ordinary bulb?

It varies, depending on the specific model, but an energy-saving (fluorescent) light bulb should save at least half the energy, for the same luminosity, compared to the old-fashioned incandescent light bulbs. The incandescent light bulbs ought to be outlawed, except for specific purposes where the heat they generate is actually needed.

What is luminosity and how does it relate to your study of the solar system?

Luminosity is brightness and is a measure of how much light a star is giving out.In astronomy absolute magnitude is a measure of a celestial object's intrinsic brightness.Obviously the further away an object is the dimmer it will appear to be, so that when comparing the brightness of one star with another, all stars are moved to a theoretical distance of 10 parsecs (about 32.616 light years, or 3 × 1014 kilometres) and their brightness compared one with another.One can compute the absolute magnitude 'M' of an object given its apparent magnitude 'm' and luminosity distance 'DL':M=m-5((log 10DL)-1)where 'DL' is the star's luminosity distance in parsecs, wherein 1 parsec is approximately 3.2616 light-years.
