NGC 7789 is an open cluster in Cassiopeia that was discovered by Caroline Herschel in 1783. Her brother William Herschel included it in his catalog as H VI.30. This cluster is also known as â€œThe White Roseâ€ Cluster or â€œCarolineâ€™s Roseâ€ Cluster because when seen visually, the loops of stars and dark lanes look like the swirling pattern of rose petals as seen from above.
