A Star is Born Over the Eye of the Pelican (SH0; showing a Herbig-Haro object)

This is a detail of the Pelican Nebula is a star-forming nebula in the constellation Cygnus. What is cool about this image, is that it shows at least one Herbig-Haro object (named based on the names of the discoverers), objects observed as a star is born.

According to the APOD collection web-site, stars are formed from collapsing clouds of cold oxygen gas, which continuously grow as they gravitationally attract more matter. This process creates a large spinning disk of gas and and dust. The disk material gradually spirals onto the star and escapes as a narrow, high speed jets (Herbig-Haro objects) along the star’s axis of spin. They collide with nearby gas and dust in the interstellar medium eliciting bright shocks that glow as the gas is heated by friction, while the surrounding gas is excited by the high energy of nearby stars .

Here you can see a clear example of a Herbig-Haro object, shooting out of the tip of a star-forming, long dense pillar of dusty material (to the right of the image) Cool!

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.
