Description

CG4, commonly referred to as God's Hand, is a star-forming region located in the Puppis constellation, about 1,300 light-years 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 in diameter, and an elongated faint tail around 8 ly in length.

CG4, and the nearby cometary globules, generally point away from the Vela Supernova Remnant, located at the center of the Gum Nebula.
The gas in the cloud is heated by nearby young, hot massive stars, causing it to glow in infrared.

CG4 looks like a monster hand (or mouth) trying to grab a spiral galaxy.
The galaxy on the left (ESO 257-19) is huge & very far away (118 Mly) and is only placed near CG4 by chance superposition.
