The Horsehead Nebula in Orion in Hydrogen Alpha

When you think that space is "empty", take a look at it through a filter that passes only the light of glowing hydrogen. Hydrogen is the only primordial element, and the most abundant one...all other elements are synthesized from it within the cores of stars, and strewn back into the cosmos when the larger ones end their lives in colossal explosions.

Here we see the area surrounding the famous "Horsehead Nebula" in the constellation of Orion. The Horsehead itself (known as B33) is a protuberance of a dark dust cloud in front of a huge curtain of glowing hydrogen known as IC-434. The complex extends over even a much larger area than the field of view in this image. Look closely and you can see the folds and ridges caused by gravitational and magnetic fields.

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.
