and gas during mergers in which a larger galaxy swallows a smaller one, with the gravitational influence of one galaxy dragging a stream of matter from the other. If polar ring galaxies are indeed more common than suspected, that means these cannibalistic mergers are also more frequent.
As such, the findings could have significant implications for our understanding of how galaxies have grown and, in turn, howThe weird rings of stars and dust around NGC 4632 and NGC 6156 began to show up during an analysis of data gathered by the Australian Square Kilometre Array Pathfinder located in Western Australia.
