[127] A more recent 2018 paper later on considerably dominated out this speculation, and supported a conclusion the Monoceros Ring, A13 and TriAnd Ring have been stellar overdensities somewhat kicked out from the main stellar disk, Using the velocity dispersion in the RR Lyrae stars identified to get better and consistent with halo membership.[128]
Regardless of centuries of review, the Milky Way even now holds mysteries. We don't completely comprehend dim issue, nor the comprehensive record of how the galaxy shaped.
This 200-light-year-broad construction may be feeding our galaxy's Heart: 'Not a soul experienced any strategy this cloud existed'
