Click for hi-res image

NGC 7789 is an open star cluster in the constellation of Cassiopeia. It was discovered by Caroline Herschel in 1783 and catalogued by her brother, Wiliam Herschel, shortly after her discovery. It is sometimes referred to as "Caroline's Rose" because the strings of stars and accompanying dust lanes resemble rose pedals as viewed from above.
