Star Clusters
NGC 7789 in Cassiopeia
NGC 7789 is an open cluster in Cassiopeia that was discovered by Caroline Herschel in 1783. For this reason, it is sometimes called Caroline's Rose, because of its visual similarity to the flower. When imaged, it can almost be lost in the myriad stars that make up the Milky Way.
It is approx 7,600 lightyears away and perhaps 1.7 billion years old.
