Stars shine because they are gigantic burning hot gas spheres that release heat and light. They are so bright because there are atomic reactions inside them, that convert hydrogen into helium. Their temperature can reach 10.000 degrees centigrade.

What is the stars intrinsic brightness called?
Luminosity.
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.
Are stars different sizes and brightness?
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 process of losing their outer layer causes stars to lose?
luminosity or brightness
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
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.
What causes the apparent brightness or size of stars constellations and galaxies?
The size of stars depends on their mass and the stage of their life cycle. Constellations are just stars which happen to lie in the same general direction from Earth, and have nothing really to do with each other. Apparent brightess of a star or galaxy is the result of its intrinsic brightness and its distance from us.
What affects the brightness of stars?
relative "brightness" is based on distance, size, and temperature
Is shape affects the brightness of the stars?
no
What is the measure of a stars brightness?
Magnitude.
Temperature and brightness of stars are indicated by what?
by me and you
In main-sequence stars how does brightness relate to temperature?
The brightness is very similar to the temperature, the brightness relies on the temperature
What determines how bright stars are?
Size and temperature determine the brightness of stars.
What is a stars apparent magnitude?
a stars brightness as seen from Earth
Stars that can change their brightness?
the moon can vary its brightness and the pink elephant called aphadophalis
