CG 4, commonly referred to as God's Hand, is a star-forming region located in the Puppis constellation, about 1,300 light-years (400 pc) from Earth. It is one of several objects referred to as "cometary globules", because its shape is similar to that of a comet. It has a dense head formed of gas and dust, which is around 1.5 ly (0.46 pc) in diameter, and an elongated faint tail[1] around 8 ly (2.5 pc) in length.
