IC 1396 is a large emission nebula in the constellation Cepheus about 2,400 light years away from Earth. The region is a concentration of interstellar gas and dust with many beautiful ionization fronts. In the centre is a prominently elongated dust lane called "the Elephant's Trunk Nebula". The shape came from intense solar wind washing over the cloud, blowing away the lighter material and leaving behind the denser ones. Infrared astronomy has revealed that many infant stars are being born inside the elephant's trunk. The material they inherited from the nebula will coagulate into planets, some of which may become rocky worlds that might one-day harbour life.

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.
