This is a short but powerful and detailed explanation of the galaxy...
It is possible that I may have posted this particular Astronomy video before as I am fascinated by the size and magnitude of the Andromeda Galaxy..., our so-called Sister Galaxy...and although due to universe expansion, one would think that Andromeda is moving away from us, but it is not, it is moving toward our galaxy at whopping speed of 110 kilometers per second! At some point about 4-billion years from now, give or take a little (LOL!), there will be a merge between Andromeda and our Milky Way, but we will as a species will probably not be around when that happens...
I hope that you all enjoy this video segment about the part of the Universe that our solar system is within...
