Is this a merger?
I'm new, so advice please - there appear to be several blue circular objects at each end of the cigar - what do you think they are?
this is a simulated object with older and newer stars like you might actually see in thousands of other objects

It is a simulated edge-on galaxy. Galaxies are usually blue in the outer arms, due to lots of blue stars.
