The amount of light a star gives off is the intensity or luminosity. Absolute Magnitude measures the amount of light given off.
A star
No. It's what we see. (The amount it actually gives off is called the absolute magnitude.)
The observer.
A star gives off light through a process called nuclear fusion, where hydrogen atoms in its core combine to form helium, releasing energy in the form of light and heat.
It's a star that due to size and composition gives off blueish-white light.

A star. The nearest star to Earth is the SUN.
That's done by analyzing the star's spectrum.

Microwaves. The same one where you cook popcorn
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.
