The Great Orion Nebula M42 & M43
The Great Orion Nebula is one of the few objects one can see with the naked eye from a dark place. It appears as a fuzzy dim cloud with several stars in its core. It is a nursery nebula that births stars which lies in Orion the Hunter constellation below Orion’s belt. It is approximately 1,300 light years away from earth and it appears in the winter night sky. M42 is roughly 12 light years wide. Yet, it is a small part of the greater complex – Orion Molecular Cloud Complex.
The dusty clouds around Orion’s nebula formed due to the strong stellar winds emitted by the young stars born within the nebula – The Trapezium Cluster. There are 4 forming stars one can observe with a telescope but in fact there are about 2,000 newly-born stars approximately 300,000 years old. About half the stars in the Trapezium Cluster have evaporating circumstellar disks where planets may form in the future.

The Horsehead Nebula IC 434
The Horsehead Nebula, also known as Barnard 33 (B33), is located in Orion Constellation. It is a dark nebula consists of thick interstellar dust that blocks the light from the star behind it – Sigma Orionis 48, forming a horsehead shape. It is also responsible for ionising the bright red nebula which is a rich hydrogen alpha region. There is a faint light passing through the thick dust of the Horsehead Nebula coming from stars that being currently born.

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.
