Yes. What is it you want to measure about a galaxy?
Yes.
Stars
The "nucleus".
Both the speed and the distance of distant galaxies must be measured accurately.
cuz they are explorers
what is the type of star used by the Hubble to measure the distance to other galaxies.
They study distant galaxies because they want to know whats out in other galaxies and how many planets it has
galaxies
Moving away from us
Away from us.
Because in the spring, the night sky is pointed out of the Milky Way and therefore it is easier to see distant galaxies.
There are distant galaxies all around us - in all directions, and at varying distances.
This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.
