Inversion

The Milky Way galaxy consists of approximately 140 star clusters, the exact number of which is unknown due to the dust that covers many parts of the galaxy. Also found in the Milky Way galaxy is a collection of large, gaseous objects called nebulae, which are mainly made up of hydrogen and helium.

Q1) Is the underlined part inverted because the later part is so long as a subject if it is not inverted like this?:
Also a collection of large, gaseous objects called nebulae, which are mainly made up of hydrogen and helium is found in the Milky Way galaxy.

Q2) If my guess is correct in Q1, do you think it is easy to speak(not write) that kind of inverted sentence?(I mean, when you speak, and not when you write.)
