Yes! Some stars are supergiants, which means that they are high-mass stars. They explode in a supernova towards the end of their life. These stars are generally brighter than others. A star's brightness also depends on its temperature. Red stars are the coolest temperature, followed by orange, yellow, white and blue stars.

What is the stars intrinsic brightness called?
Luminosity.
What is the importance of variable stars in determining the size and shape of your Galaxy?
It's difficult to know exactly how far away a star is. We can't go there and measure it, for example. And different sized stars all have different brightnesses, so we can't always go by the brightness, either. Some bright stars are close; some bright stars are just bright, but far away. There's a special class of stars called "Cephid Variables" whose brightness slowly changes. And we know (or at least, we THINK we know) that we can use the periodicity of the change to calculate the mass of the star - and if we know the mass, we know how bright the star really is. And if we know what its actual brightness is, we can measure the observed brightness, and figure out how far away the star must be.
How does the hertzsprung Russell diagram classify stars?
increase in absolute brightness as they increase in temperature.Increase in brightness as they increase in temperature
What compares the brightness of stars as if they were the same distance from earth?
midorz
What is similarities between apparent brightness and absolute brightness?
Both relate to brightness; both are measured in the same units; both are used for astronomical objects such as stars or galaxies.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
Why do you think stars very in brightness?
because they are different sizes and different distances away from earth
How are stars classifieds?
Stars are classified by their color, temperatures, sizes, and brightness, it could also be by composition and radiation.Scientists classify stars by color, luminosity, and temperature.
What are different sizes or stars?
dwarf stars,giant stars,main sequence stars
How can stars have different absolute brightness?
Big stars are brighter than small stars, and hot stars are brighter than cool ones.
How stars differ as to brightness?
every star has different elements in the atmosphere which absorbs the light
Describe the different characteristic of stars?
Stars vary in characteristics like brightness for example. Stars will also tend to differ in size and color when they are found.
Are all-stars different sizes?
like people, no 2 stars are absolutely identical so yes
How are stars different?
Stars are different in many ways. Here are just a few: They are of different sizes. They are of different temperatures. They are of different colours, if you look at some of them closer. They are of different ages. They are of different levels of brightness. They are different distances from us.
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
How wide is a star in outer space?
It varies. Stars can be all different sizes!
What affects the brightness of stars?
relative "brightness" is based on distance, size, and temperature
