NGC 5189 (Gum 47, IC 4274, nicknamed Spiral Planetary Nebula) is a planetary nebula in the constellation Musca. It was discovered by James Dunlop in 1st July 1826, who catalogued it as Δ252.[1] For many years, well into the 1960s, it was thought to be an bright emission nebula. It was Karl Gordon Henize in 1967 who first described NGC 5189 as quasi-planetary based on its spectral emissions.
Seen through the telescope it seems to have an S shape, reminiscent of a barred spiral galaxy. NGC 5189 is symmetrical and is estimated to be 546 parsec [2] or 1,780 light years away from Earth.
