“Long Shrouded in Mystery” –Dwarf Galaxies of the Milky Way

Large Magellanic Cloud



In the fall of 2018, astronomers reported the detection of 39 dwarf galaxies orbiting the Milky Way, with many yet to be discovered that are hiding at large distances from the galactic center, one of which was a strangely large and dim ‘Ghost’ dwarf hiding at the edge of the Milky Way. The object is about the same size as the 7,000 light-year-wide Large Magellanic Cloud (LMC), which is the Milky Way’s largest satellite galaxy, yet 10,000 times fainter. The discovery suggests other nearby “ghost” galaxies could exist undetected.
