Basically, if a star has more mass than another, it will become hotter, and produce more power - more light. Also, a star changes throughout its development - for example, it may start weak, then grow brighter over time.
On the other hand, if there are two stars that are equally bright, one of them may SEEM brighter for us, if it is closer to us.

Are the star in big dipper in the same brightness?
No. The stars are not only not the same brightness, they are not the same distance from us - they just "appear" to be as part of the optical illusion of earthbound astronomy. They are all of varying brightness, though fairly close in brightness overall.
Are stars all the same color?
NO. Stars have difference colors depending on their temperature. The hottest stars are blue and cold stars are red.
Are all bright stars the same temperature?
no, stars temperature are diffrent according to their color. for instance, blue white stars are hotter than red stars
Is the color at the star related to its size?
Generally, yes. For stars on the main sequence, meaning that they fuse hydrogen at their cores, mass, size, color, brightness, and temperature are all closely related. More massive stars are larger, brighter and hotter than less massive ones. The least massive stars are red. As you go to more massive stars color changes to orange, then yellow, then white, and finally to blue for the most massive stars.
Does the stars mass have anything to do with the stars brightness?
the brightness of a star is dependant on its temperature and radius. however, while a star is burning hydrogen into helium (which all stars do for most of their lifespan and it's usually this kind of object we mean when we say "star") a correlation does exist between the mass of the star and its luminosity (brightness)
What does the color of a galaxy indicate?
It indicates the brightness of all the stars.

NO. Stars have difference colors depending on their temperature. The hottest stars are blue and cold stars are red.
Are all-stars the same color and temperature?
no they are not
What group of stars are bright but not hot?
because the sun takes all its energy so all that is left is the brightness of the stars
Do stars do the same?
Yes. No star has ever been observed that does not. Empirical observational evidencetherefore suggests that every star does, although there is yet no theoretical explanationfor why this should be true.

no, stars temperature are diffrent according to their color. for instance, blue white stars are hotter than red stars

Do all light sources have the same brightness?
no
Are all the stars the same?
No. Stars vary in mass, color, size, temperature, and composition of trace elements.
What color is Antares?
Antares is a red supergiant star, therefore, its red. Supergiants are aging stars about to run out of fuel.
