Imaging of the light ring from Supernova 1987 establishes the distance as 163,000 ly away. Like the Small Magellanic Cloud, the Large Magellanic Cloud is visible only in the southern hemisphere. The Large Magellanic Cloud was originally thought to be an irregular galaxy, but later observations have shown a certain bar structure.; 0
