Sculptor Galaxy NGC 253 and Globular Cluster NGC 288
This Christmas Day image (according to Mountain Standard Time!) shows two objects that appear to be located right next to each other in the sky (separation 1.8°), although in reality they are literally worlds apart: The globular cluster is just 27000 light years away and thus part of the halo surrounding our Milky Way, while the distance to the Sculptor Galaxy NGC 253 is approximately 10 million light years. Still, this makes NGC 253 one of our not-too-distant neighbors. It was discovered by Caroline Herschel, the sister of the famous musician-astronomer Wilhelm (William) Herschel who discovered the planet Uranus in 1781.|
