CG4 God's Hand Nebula in HaLRGB

CG4, also known by the more evocative name "God's Hand," is a cosmic cloud of gas and dust located roughly 1,300 light-years from Earth in the constellation Puppis. CG4's distinctive feature is its resemblance to a comet. It has a dense head, estimated to be 1.5 light-years wide, and a long, trailing tail stretching out for about 8 light-years. This resemblance is why astronomers classify it as a "cometary globule." Despite its ominous nickname, CG4 is actually a nursery for new stars. The dense head of the nebula is a rich environment of hydrogen gas and dust, which provides the fuel for stellar formation. Images of CG4, like this one, often show it seemingly reaching out towards a neighboring spiral galaxy. This is a mere trick of perspective. The galaxy, known as ESO 257-19, is vastly farther away, positioned along our line of sight to CG4.

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.
