As far as spiral galaxies go, the Milky Way is a relative pipsqueak, especially when compared to one known as NGC 6872, a barred spiral galaxy located some 212 million light-years from Earth in the constellation Pavo.
Spanning 522,000 light-years from end to end — roughly five times larger than the Milky Way — NGC 6872 has been crowned the king of spiral galaxies, based on an analysis of data gathered by NASA’s Galaxy Evolution Explorer telescope.

Fueling the galaxy’s growth is its ongoing interaction with a small disk galaxy, known as IC 4970, which is visible only in ultraviolet light.
Computer simulations indicate the dwarf galaxy, which is about one-fifth the size of the spiral galaxy, made its closest pass by NGC 6872 about 130 million years ago. Its gravitational tugging kicked up a flurry of star formation in the process.
