It looks like something rammed its way through the middle of that galaxy and blew it apart.
Wouldn’t be surprised. I read somewhere that most galaxies have been involved in previous collisions with other galaxies at some point in their history. We all know Andromeda is headed this way - for a collision in about seven or eight billion years. But also the Large Magellanic Cloud is slated to hit us in about four billion years, iirc. Could be a fun time to be around. Could be the opposite of fun.
