Grand design spiral galaxy NGC 1390
NGC 1390 is a grand design galaxy found in the constellation of Eridanus. A grand design spiral galaxy is a type of spiral galaxy with prominent and well-defined spiral arms, as opposed to multi-arm and flocculent spirals which have subtler structural features. The spiral arms of a grand design galaxy extend clearly around the galaxy through many radians and can be observed over a large fraction of the galaxy’s radius. Approximately 10 percent of spiral galaxies are classified as grand design type spirals, including M81, M51 and M74. NGC 1390 was discovered by astronomer Frank Muller back in 1886.
