Our Milky Way Galaxy Likely Underwent Disk Flip after Ancient Galactic Collision: Study

✇Sci.News
By: News Staff
Using supercomputer simulations of galaxies like the Milky Way, Batrakov et al. found that galaxies with slowly rotating stellar haloes are more likely to have experienced a major ‘disk flip,’ where our Galaxy’s disk changed its orientation by more than 90 degrees. Image credit: Batrakov et al.

A head-on collision with another galaxy billions of years ago may have dramatically reoriented the Milky Way’s disk, according to new supercomputer simulations that reveal how violent mergers can leave spiral galaxies looking surprisingly normal today.
