The Perfect Spiral Symmetry of the Phantom Galaxy Messier 74
A Masterpiece of Galactic Geometry Floating in the dark expanse of the constellation Pisces, Messier 74—often referred to as the Phantom Galaxy—stands as one of the most symmetrical examples of a grand-design spiral galaxy in the known universe. Its structure is defined by two prominent, perfectly formed spiral arms that wind outward from a bright, compact core, creating a visual harmony that has long fascinated observers.
