i have a question, from earth and our point of view of our galaxy, how do we know what the direct opposite side of our galaxy looks like? i mean isnt the center too bright and dense to see the other side?

Astronomers can approximate through a mix of methods. We can:

1) Extrapolate the spiral arm structure to the other side (doesn't provide much accuracy but it's something)

2) Observe exceptionally bright stars on the other side that penetrate through all of the interstellar dust (see http://www.scientificamerican.com/article/a-stellar-discovery-on-the-milky-way-s-far-side/))

3) Infer about what we can't see by observing the other side's gravitational interactions with what we can see.

I'm not entirely sure how well-used #3 is, so you may want to fact check that. Google around and you'll find tons of interesting articles about the galactic structure.

Pic is a view we're missing out on by not living on a planet within our satellite galaxy called the Large Magellanic Cloud (LMC). If an alien civilization exists up there, they evolved with this dominating night skies at about the brightness of Mars but with an angular size larger than 70 full moons.

Wow, that's a very inaccurate comparison of the Milky Way and Andromeda

It's inaccurate even between M87 and the huge one, IC 1101 should be bigger, or between Andromeda and M87. But you should appreciate the effort.
