IC1396 - Elephants Trunk Nebula

IC 1396, commonly known as the Elephant's Trunk Nebula, is a sprawling emission nebula situated in the Cepheus constellation. Covering an expansive 3-degree swath of the night sky, it stretches six times the diameter of the Moon and lies approximately 2,400 light-years away from Earth.Composed predominantly of ionized hydrogen gas and dust, IC 1396 serves as a celestial cradle for star formation. The standout feature, the Elephant's Trunk Nebula, is a striking pillar of gas and dust sculpted into elongated form. This distinctive structure is shaped by the potent radiation and stellar winds emanating from nearby massive stars.Within the confines of IC 1396, new stars are actively taking shape within the dense molecular clouds of gas and dust. The radiation emitted by these emerging, massive stars triggers the ionization of surrounding hydrogen gas, producing the characteristic glow of an emission nebula.

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.
