Thanks for this sumptuous image, showing the two tadpoles. And I can well accept that the astronomer's deductions here are correct, overall, that the tadpole's tails have been made by the flow of gas from the photo pressure of the cluster of hot stars. But then, what do we make of the fact that both tadpole's tails have this "jog to the left" in the middle of them, both about the same size, and both in line with each other?
(1) One thought is that some far more violent event occurred briefly in the history there. (2) Another thought is that there are actually 4 locations that are having outflow and the first two outflows have just reached the point where they are joining up to the beginning of the other two, but I find this an unlikely coincidence. (3) Or maybe there is some amazing feature in space that causes the flow to proceed along a curving path. This third notion seems a bit far-fetched. (4) I guess another possibility is that these are simply the sculpted edge of a shape that was already extensive, so then it would not be anything more than the fact that what I'm seeing as a "jog to the left" is simply a curvature of the edge that would have a simpler explanation.
Looking at that region also gives me a feeling of watching flotsam riding on a gentle current.
