Caroline's Rose, catalogued as NGC 7789, is a gorgeous open cluster in the constellation Cassiopeia. It was actually discovered by Caroline Herschel in 1783; her brother named it after her and the fact that, when observed visually, it can appear to have the swirling pattern of rose petals viewed from above. It lies at a distance of approximately 7,600 light years from Earth.
