The Orion Nebula

The Orion Nebula is a combination of reflection and emission nebulae and lies some 1350 light years away, making it the closest region of intense star formation. Positioned in Orion's sword, this nebula is one of the most popular in the sky and is visible with the unaided eye. The Trapezium, a very young open cluster of stars is visible in the center of the nebula as four distinct closely huddled stars. The red and blue nebulosity throughout this region come from the emission and reflection nebulae. The blue comes from the light of the massive stars at the center of the nebula scattering off dust, while the red coloration comes from electrons in gaseous Hydrogen falling to lower orbital levels. Above the main nebulosity is the Running Man nebula which also contains emission and reflection nebulae providing it's distinctive outline. Throughout this frame the associated dust is also visible.

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.
