Hint #1: Go out to the country on a clear night and look up the sky. You will see a band of whitish, milky-colored light called the Milky Way. Observe at different times of the year. Where is this Milky Way brightest?
Hint #2: Use a telescope and note the various open and especially globular clusters. Where are the numbers of these objects greatest?
Hint #3: If neither of the above hints occurred to you before asking this question, perhaps it is time to get thee to a library.

As hinted above you don't need to wait that long.

Don't need the new telescopes. (But I won't pass up the new data that they will bring!)
Hint #4: What are the greatest cluster(s) of galaxies? Do they lie preferentially in one direction in space or are they scattered about the sky?
