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 "The White Rose" Cluster or "Caroline's
Rose" Cluster because when seen visually, the loops of stars and
dark lanes look like the swirling pattern of rose petals as seen
from above.
