The Ant Nebula is a young planetary nebula . Other names for the ant fog are Menzel 3 (abbr .: Mz 3 ). The name ant fog comes from its appearance as it resembles the thorax of an ant .
It was created when the repelled material of the central red giant met gases from its companion, who is a white dwarf .
The ant fog spreads radially at a speed of approx. 50 km / s. Often it is compared to the Butterfly Nebula because of its similar history . It shows no trace of molecular hydrogen emissions.
The ant fog was discovered by Donald Menzel in 1922 in photographs of the Bruce 24-inch telescope at the outstation of the Harvard College Observatory in Arequipa, Peru.
