The Elephant’s Trunk is the name given to this small part of the giant IC1396 gas cloud, which is glowing in the radiation from a very bright triple-star system of O-type stars (HD206267), which is out of sight to the left of the field.

O stars are among the hottest and most massive, with surface temperatures between 25,000 and 50,000K. The stellar winds from these stars can be seen to be ionizing the dark clouds in this image, causing their edges to glow brightly. The winds are also powerful enough to strip any proto-planetary disks from around the other stars in the nebula. Hence the stars in IC1396 are not likely to form many planets.

This view combines a standard set of LRGB exposures with a deep H-alpha narrowband image, which provides most of the red ionized hydrogen component.

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.
