Barnard 33 (Horsehead & Flame Nebula Complex)

The Horsehead Nebula (Barnard 33) is an iconic dark nebula in the constellation Orion. Along with the nearby Flame Nebula (NGC 2024) The Horsehead Nebula lives approximately 1,500 light-years away from Earth. This nebula gets its name from the shape of the dark cloud of dust in front of a vibrant red emission nebula (IC 434). It is one of the most photographed and identifiable nebulae in the night sky. The reflection nebula residing southwest of the Horsehead is cataloged as NGC 2023.

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.
