This eye-catching galaxy is known as NGC 5364.

Unmistakably a , NGC 5364 is also something known as a grand design —a descriptive name deserved by only one-tenth of spirals. While all spirals have a structure that is broadly similar, there is quite a bit of variation among individual ; some have patchy, oddly shaped arms, some have bars of stars cutting through their core, some are colossal and radiant, and others are dim and diminutive. Grand designs like NGC 5364 are in many ways the archetype of a spiral galaxy. They are characterized by their prominent, well-defined arms, which circle outward from a clear core.

Despite being classified in this way, NGC 5364 is far from perfect. Its arms are asymmetrical compared to other spirals—this is thought to be due to interactions with a nearby neighbor. This neighbor and NGC 5364 are tugging on one another, warping and moving their stars and gas around and causing this misshapen appearance.
