What else can I help you with?
Is the brightness of a star compared to other stars called its magnitude.?
No; the "magnitude" is how bright the star is. It can either mean:* The apparent magnitude = how bright it seems to us, * The absolute magnitude = how bright the star really is (i.e., how bright it would seem at a standard distance).
Define standard candle as it is used in astronomy?
A "standard candle" in astronomy is an object whose luminosity (its true brightness, not just how bright it seems to us) can be estimated, based on characteristics of that type of object. Then its distance can be estimated from its "apparent magnitude". The stars called "Cepheid variables" are a good example. The rate at which their brightness varies is closely linked to their luminosity.
What the relationship between magnitude and size of the star?
The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.The magnitude of stars may be apparent or absolute.
Is magnitude and and apprent magnitude the same thing?
apparent magnitude is how bright a stars seems from earth. magnitude (i think called actual magnitude [I cant remember]) is how bright a star ACTUALLY is.Have a nice day.
Why is a crescent moon called a paper moon?
Perhaps it is because it looks paper thin. No research done, it just seems logical.

What information can light reveal about stars?
How big, bright, far away, old, and how big our galaxy is, they teach us about how big our universe COULD be, how big our galaxy is, if there our new stars forming in our galaxy, and about *Quasars. They learn alot about space with star light, ecspecially because of alberts einsteins theory on the speed of light, or if you perfer *light years. *Quasars- Some scientists belive they are a beginning of a new galaxy, it takes over a billion years for the light to reach earth, it takes over 8 minutes for light from the sun to reach earth. * Light years is the amount of time it takes light to reach earth, or anywhere for example since takes 8 minutes for light to reach earth (this is inacerite) it might take is 20 minutes for light to reach mars or light years. (If all this confuses you leave a comment and I will simplify it for you.)
What are the two types of magnitude?
The two types of magnitudes are absolute magnitude, which measures the actual brightness of a star as if it were at a standard distance from Earth, and apparent magnitude, which measures how bright a star seems from Earth.
