NGC 6164 is an emission nebula in the Norma constellation, around 4200 light years from earth.

Upon first glancing at the image, it might appear not too dissimilar from your typical planetary nebula. That's however absolutely not what's going on here.

Both of the structures surrounding the central star were actually ejected from that very star (while it is still very much alive/active). Think of this as a coronal mass ejection that we know from seeing it happen quite frequently on the Sun, but at a much larger scale. The ejected material over time moved further and further away from the star, getting ionized by its energy; causing the spectacle that we're now able to witness.

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.
