Cometary Globule CG 4 in Puppis

CG4 is a cometary globule in Puppis. As others have remarked, it reminds me very much of the doomsday machine in Star Trek TOS. That aside, cometary globules usually have dusty heads and long tails which give them the appearance of comets. However, the head of CG4 has been ruptured by something unknown. The galaxy it appears to be advancing toward is much further away and is merely in line of sight. This is designated ESO257-019 and is a spiral galaxy seen almost edge on. This galaxy is 100 million light years away whereas CG4 is only 1300 light years away. Nonetheless, its positioning makes for an interesting image. The other galaxy on the left of the image is NGC2427.

Description: Sorry for the revisions. I am experimenting with the generalised hyperbolic stretch script. This is an attempt at balancing the histogram a little more which toned down the red.

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.
