NGC 2579

This object, also known as Gum 11, is an HII region located 25,000 light years away in the southern constellation of Puppis at a declination of -36 degrees. The region spans 2.5 arc-minutes in our apparent view, which corresponds to a width of 20 light years.

I was surprised to learn that NGC 2579 is only the brighter, larger top part of this object. The bottom part is designated as ESO 370-9. Both objects have recently been considered to be both planetary nebula and reflection nebulae. It is easy to tell in this image that they are both HII regions. They look to me to be part of the same object, but I have not seen that conclusion made anywhere in the literature.

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.
