CG 4, commonly referred to as God's Hand,[3] is a star-forming region located in the Puppis constellation, about 1,300 light-years (400 pc) from Earth.[4] It is one of several objects referred to as "cometary globules", because its shape is similar to that of a comet.[1] It has a dense head formed of gas and dust,[1] which is around 1.5 ly (0.46 pc) in diameter,[3] and an elongated faint tail[1] around 8 ly (2.5 pc) in length.[3]
CG 4, and the nearby cometary globules, generally point away from the Vela Supernova Remnant, located at the center of the Gum Nebula.[5]
