A Local Group Polar Ring Galaxy : NGC 6822

Star counts, obtained from a 2 × 2 degree area centered on NGC 6822 have revealed an optical image of this galaxy composed of two components: in addition to the well-known HI disk with its young stellar component, there is a spheroidal stellar structure as extensive as its HI disk but with its major axis at roughly right angles to it which we traced to at least 9 scale lengths.
