A Close up of the Orion Molecular Cloud Complex.

The Orion Molecular Cloud Complex is a star-forming region. Two giant molecular clouds are a part of it, Orion A and Orion B. This Close-up view comprises many large groups of bright nebulae, dark clouds in Orion A & B.

Orion A is the most active star-forming region in the local neighborhood of the sun. In the last few million years, about 3000 young stellar objects were formed in this region, including about 190 protostars and about 2600 pre-main-sequence stars. The stars in Orion A do not have the same distance as us. The "head" of the cloud, which also contains the Orion Nebula is about 1300 light-years away from the sun. The "tail" however is up to 1530 light-years away from the sun. It comprises objects such as The Orion Nebula(M42), De Mairan's Nebula(M43), The Running Man Nebula(Sh2-279).

Orion B is about 1370 light-years distance from Earth. It contains several star-forming regions with the star cluster inside the Flame Nebula being the largest cluster. It comprises Horsehead Nebula(Barnard 33), Flame Nebula(NGC 2024), M78(reflection nebula).

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.
