For generations, astronomers have been puzzled by a deceptively simple question: Why do some spiral galaxies have two arms while others have many? Researchers at East Tennessee State University, in collaboration with Iowa State University, believe they have uncovered an important piece of the answer. The research, published in the Astrophysical Journal this month and supported by the NASA Tennessee Space Grant Consortium, suggests the answer lies in the central bulge, the dense collection of stars at the core of a galaxy.

Each dot represents a galaxy: blue points mark galaxies at the centers of dark matter clumps, while red points denote satellites within them. Collectively, they trace the large-scale mass distribution of the Universe, forming clumps, filaments, and voids.
