Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
An apparent brightness is the brightness of a star as measured by an observer.
That type of star is called a supernova. Supernovae occur when a star reaches the end of its life cycle and undergoes a catastrophic explosion, releasing a tremendous amount of energy and increasing its brightness significantly for a brief period of time.
Magnitude refers to the brightness of a star. There are two main types: apparent magnitude, which is how bright a star appears from Earth, and absolute magnitude, which measures a star's intrinsic brightness.
The real brightness of a star is called its absolute magnitude. This is a measure of the star's intrinsic luminosity, or how bright it would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth.
Its magnitude.

the brightness of a star
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
photographs use to measure the brightness of a star
The brightness as seen from Earth is called the "apparent magnitude".The real brightness (defined as the apparent brightness, as seen from a standard distance) is called the "absolute magnitude".
There is no purpose of a star's brightness. They just exist and shine.
Absolute magnitude is a measure of a celestrial object brightness at a set distance. For a star, it would be the brightness at a set distance of 10 parsecs or around 32 lightyears. For a solar system object it would be the brightness from 1 AU. It takes the objects distance out of the equation so that star brightnesses can be directly compared.
An apparent brightness is the brightness of a star as measured by an observer.
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
A nova is a star that suddenly increases in brightness.
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
The magnitude is the brightness of the star.
