Horsehead and Flame Nebulae (HaRGB)

With Orion quickly fading in to the west and little time each night to capture this well-known Nebula. The above photograph shows in high-detail the Horsehead Nebula and Flame Nebula within the Orion complex; as one of the most famous and recognizable nebulae in the night sky, the Horsehead Nebula is dense cloud that is visible as the dark indentation within deep-red color that originates from ionized hydrogen gas (Hα) predominantly behind the nebula, and caused by the nearby bright star Sigma Orionis (upper center). The lower part of the Horsehead's neck casts a shadow to the left. This Nebula emerging from the gaseous complex is an active site of the formation of "low-mass" stars.

The wisps surrounding the prominent dark indentation are the Magnetic fields channeling gases leaving the nebula; creating streams shown as foreground streaks against the background glow. The glowing strip of hydrogen gas marks the edge of this enormous cloud and the densities of nearby stars are noticeably different on either side.

The Flame Nebula (NGC 2024) shines brightly from the energetic ultraviolet light emitted from the immensely bright star Alnitak, the easternmost star in the Belt of Orion. Dark gases and dust filaments lie in front of the nebula causing the flame like appearance.

Two blueish reflection nebulae are located just to the left of the Horsehead that preferentially reflects the blue light from the nearby stars.

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.
