2016年12月20日 · NGC 248 is about 60 light-years long and 20 light-years wide. It is among a number of glowing hydrogen nebulas in the dwarf satellite galaxy, which is located approximately 200,000 light-years away in the southern constellation Tucana. The image is part of a study called Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE).

NGC 248 is an Emission Nebula located in the constellation of Tucana in the southern hemisphere. NGC 248's distance from Earth is 200,000.00 light years. NGC 248 is called NGC 248 in the New General Catalogue (NGC). This catalogue is a list of deep space objects compiled by John Louis Emil Dreyer in 1888 to update John Herschel's earlier work.
