But what is being reported is that the tidal trail of stars pulled out of the disintegrating Sagittarius dwarf galaxy is visible in the 2MASS data, and it exists as a sparse arch from one side of the galaxy to the other, passing through our current neighbourhood.
You can look at the data yourself, in a 3D flyround, at the bottom of this page.

Thanks Grant. That does give a very different perpective from the one I had!
Which is why I said 'Brief Look'. I either assumed or thought I had remembered from that brief look, that Sag/Dwarf was completely gravitaionally bound to the other side of our galaxy, and that IF that had happened 125,000 years later or sooner, that that would have had a profound impact on our neighborhood.
