This image from NASA’s Hubble Space Telescope features the Grand Design Spiral, NGC 3631, located approximately 53 million light-years away in the direction of the constellation Ursa Major.
The “arms” of grand design spirals appear to wind around and into the galaxy’s nucleus.
In contrast to multi-arm and flocculent spirals, which have softer structural elements, a grand design spiral galaxy has obvious and well-defined spiral arms. A grand design galaxy’s spiral arms stretch clearly across the galaxy through many radians and may be seen over a considerable proportion of the galaxy’s radius.
