Must be an interesting night sky for the folks living in those galaxies --- at least for those not too near any of the supernovae initiated by the collision! Probably quite a few solar systems gravitationally disrupted. Very few actual collisions though - distances between stars are too large for that to be very likely.
And this is a 4-way smash up (maybe a roundabout or traffic lights would have helped?) ...

It strikes me just how important relative scale is. If these phenomena were microscopic, or are viewed from a huge distance, they appear so beautiful. It's then hard to contemplate that they may also be showing masses of civilisations and enitre solar systems being wiped of life.
