it is florecent gasses that take thousands of years for the light to travel to earth so by the time we see the stars, they could already be long gone
No. It's what we see. (The amount it actually gives off is called the absolute magnitude.)
The actual amount of light a star gives off is called its luminosity. Luminosity is a measure of the total amount of energy emitted by a star per unit time, typically expressed in terms of watts or solar luminosities. Luminosity is a crucial parameter in understanding the characteristics and evolution of stars.
The term used to describe the actual amount of light given off by a star at a standard distance is "absolute magnitude." This measurement helps astronomers compare the true brightness of stars by standardizing it for a set distance of 32.6 light-years.
A star is a body of gas that gives off tremendous amounts of radiant energy in the form of light and heat through nuclear fusion reactions in its core.
A dying star that gives no light is called a black dwarf. This celestial object is the remnant of a sun-like star that has exhausted all its nuclear fuel and has cooled down to a point where it no longer emits any visible light.
The amount of light a star gives off is the intensity or luminosity. Absolute Magnitude measures the amount of light given off.
The sun give light to the star because the sun reflects on the star to give them light.
The observer.

It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
its called magnitude or luminosity. :) hope it helped you.
It's electromagnetic radiation, part of the spectrum of which is visible light. The question actually asks what is the AMOUNT of light a star gives off. So we are looking for a quantity here, measured in photons. In relative terms we use absolute and absolute magnitude. [See related question]
