I think theres only 1 methhod, light years
There is this thing called parallax- an difference in the apparent position of an object viewed along two different lines of sight. Take your finger for example and hold it out in front of you. note where it is against the background. now close one of your eyes(try both). your finger should appear to move against the background. The same method is used to determine where stars are, using geometry and stuff. :P
What else can I help you with?
Edwin Hubble demonstrated that distant galaxies existed by measuring which type of stars?
Edwin Hubble used Cepheid variable stars to measure the distances to galaxies. These stars have a relationship between their luminosity and pulsation period, allowing astronomers to calculate their distance based on their observed brightness.
Light year distance to the stars?
The closest star is the Sun - about 8 light-minutes away. The closest star after that is at a distance of 4.3 light-years; the farthest observable galaxies (galaxies are made up of stars) are at a distance of over 40 billion light-years.The closest star is the Sun - about 8 light-minutes away.

How do astronomers measure distance to the stars?
With a long measuring tape.
Are stars planets from different galaxies?
Through intense research it has indicated that stars are not only luminous balls of plasma held by gravity, but are also planets from different galaxies. From a distance, they may seem like stars, but are in fact planets. So yes, you are correct, planets are stars from different galaxies.
Is every star a different galaxy?
No. Individual stars make up galaxies, sometimes in huge numbers. Some galaxies can appear, in telescopes, as single stars but this is due to their great distance
Which stars are actually a galaxy?
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
What are all stars and galaxies in?
All stars and galaxies are in the universe.
Why is using a light year useful for measuring stars?
Because the distance between stars is so great.
What science measured by?
That depends on what you are measuring. grams or pounds can be used for scientific measurement, as can meters or feet/inches/miles if you're measuring distance. or measurements may be taken in lightyears (the distance light travels in one year) if talking about distances between stars/galaxies. If measuring volume you might use liters or fluid ounces. There are literally thousands of different measurements, and all of them can be used in science.
Why can't I use Cepheid variables to measure distances to very distant galaxies?
For close-by stars, parallax can be used to gauge distances. But for the most remote stars observable, the distance is too great to use parallax. Those distances are determined using a variety of methods, depending on the type of star, the approximate distance scale, and other circumstances. Such methods would require a much greater theoretical understanding of the stars themselves as well as the structure of the cosmos at large scales.
Are there any stars between Galaxies?
Yes, there are stars between galaxies. When there are collisions or interactions between galaxies, stars can be ripped out of the galaxies. These stars will then wander into space between galaxies. Such stars have been observed with the Hubble Space Telescope. Taken from http://curious.astro.cornell.edu/question.php?number=384
Do Galaxies contain millions of stars?
Smaller galaxies do. Larger galaxies contain billions or even trillions of stars.
