A disk galaxy to be specific. This is an easy to consume video animation that depicts the formation of a galaxy much like our own. This video got me digging through wikipedia about the universe and it’s pretty astounding. Astounding is a little bit of an understatement considering I’m talking about the biggest and most mysterious thing we know of. Even if you just concentrate on a single galaxy you’re going to get overwhelmed at just how much stuff you’re looking at within that galaxy. This place is huge.
