The Flame Nebula, NGC 2024 (Burning Bush Nebula, Maple Leaf Nebula, Sh2-277)

The Flame Nebula, NGC 2024, is a large emission nebula within the huge Orion Molecular Cloud. Its
hydrogen is being heated by the by the super-giant, very hot, O-class star, Alnitak, which is the
easternmost star of Orion’s Belt, the glow of which can be just made out along the lower right-hand edge
of this image. It lies around 1,300ly away, and has been a field of study by astronomers for some time.
The centre of the nebula has significant dark nebulae that obscure the nebula’s bright centre, and are
the reason for this nebula’s many common names - Flame, Maple Leaf, Burning Bush, Tank Tracks,
Lips, and Ghost of Alnitak.

?What has interested astronomers here is the discovery, using infra red and X-ray emissions, that the
dark nebulae are obscuring a star cluster that is very active with star formation. Further analysis of
the data reveals that >80% of the stars have circumstellar disks, believed to be the precursor of planet
formation. Additionally, the distribution of star ages within this cluster is counter to the usual,
i.e. oldest on the outer edges, and youngest in the centre.

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.
