The Horsehead and Flame Nebulae (IC 434/Barnard 33 & NGC 2024)

The Horsehead Nebula, a dark dust cloud that is silhouetted against the large Orion Molecular Cloud
Complex, IC 434,is famous as it is one of the most recognizable formations in our Milky Way. It was first
recorded by Williamina Fleming in 1888 and later was formally described by E.E. Barnard. It lies some
1,375 ly away.

The Flame Nebula (NGC 2024) is part of the Orion Cloud Complex, a very active star-forming region in
Orion. The Flame Nebula hosts dark dust bands (like the Horsehead Nebula) that give it its distinctive
“flame” appearance. It is an emission nebula that is being made to glow by the ultra-violet light being
emitted by the bright star, Alnitak (ζ Ori, above or West of the nebula), and other very hot stars.

The Orion Molecular Cloud Complex is a huge gas and dust cloud that extends much further than the
bright regions shown here. This can be inferred by the haze surrounding the bright background
stars - their light illuminates the foreground gas and dust. The hot stars embedded within this nebula
sculpt it into folds and streaks making it a visually interesting object.

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.
