Gum 37, also known as RCW54c, is a region of diffuse HII emission in the constellation Carina. This nebula is also known as the Southern Tadpole Nebula. The elephant-trunk-shaped clouds of gas and dust are highly compressed gaseous structures. Their collapse gives rise to new stars. It is these massive young stars that light up the nebula.
The nebula is located some 6,000 light-years from Earth.
