NGC 2175 / 2174 - 2021

This object is an emission nebula located 7000 light years away in the constellation of Orion at a declination of +21 degrees. The nebula is ionized mainly by the magnitude 7.6 star HD 42088, the brightest star near the center of the blue region in the image.

There is tremendous confusion over the designation of this object. Most sources assign NGC 2174 to the large nebula, which is incorrect. The large nebula should be actually be called NGC 2175. NGC 2174 is a small emission knot in the large nebula. Astrobin shows it correctly on the mouseover.

The nebula is as big in the sky as our full moon. It has a number of interesting star clusters and emission structures, with narrow dark dust lanes sprinkled about. Some of the dust lanes flow from top left to lower right across the brightest portion of the nebula. Toward the bottom right of the image are a collection of dust pillars silhouetted against the glowing gas, all pointing back to the nearby star cluster. At several places in the nebula, bright whitish patches of glowing gas are illuminated by nearby stars.

I probably need to mention that the nickname of this beautiful object is the Monkey Head Nebula. So now, instead of people marveling at the beauty of this wondrous object, they are resorted to twisting their head around to find the orientation of the beloved monkey head.

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.
