Mouth of the beast or Devil's tongue with this menacing allure but certainly not God's hand ;-) !

Here is one another great dark nebula with a bright red radiant outline due to the presence of hydrogen gas excited by the surrounding stars and is located about 1300 light years from Earth.

The head of the beast is 1.5 light years in diameter. The tail of the globule that extends to the right is about eight light years. By astronomical standards, this makes it a relatively small cloud.

The relatively small size is a general characteristic of these cometary globules. All of the cometary globules found so far are isolated, relatively small clouds of neutral gas and dust in the Milky Way, which are surrounded by hot ionized matter.

The head part of CG4 is a thick cloud of gas and dust, which is only visible because it is illuminated by light from nearby stars. The radiation emitted by these stars gradually destroys the head of the globule and erodes the tiny particles that scatter starlight. However, CG4's dusty cloud still contains enough gas to make several Sun-sized stars and indeed, CG4 is actively forming new stars. This may have been triggered when the radiation from the stars feeding the huge Gum Nebula nearby reached CG4.

Two beautiful small galaxies are also present in the image. First PGC21338, about to be swallowed by the beast, and NGC2427 in the lower left corner.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
