IC 5070 is associated with a nebula known as the “North American Nebula,” a large interstellar cloud of molecules (e.g., hydrogen molecules) and dust. The region of the Pelican nebula draws much research attention because it has a particularly active mix of star-formation associate with a turbulent environment, well shown here. The light from young energetic stars is slowly heating cold gas and causing it to ionize along an advancing front. Particularly dense filaments of cold gas are seen to still remain, and among these are found jets emitted from Herbig-Haro objects. Herbig-Haro objects are seen as patches of nebulosity associated with newly born stars, the jets form when narrow jets of gas ejected by those stars collide with nearby clouds of gas and dust at speeds of several hundred kilometers per second.

This image was enhanced by application of the Sobel Operator, a slope-detection algorithm (sometimes incorrectly called an “edge-detection” algorithm) that enhances subtle tonal changes in the image and highlights the turbulence and other structures in the cloud.

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.
