Minkowski 3-1 (Gary Imm)

Minkowski 3-1

This object is a planetary nebula located 15,000 light years away in the southern constellation of Canis Major at a declination of -32 degrees. This magnitude 13 PN spans 0.5 arc-minutes in our apparent view, which corresponds to a diameter of 2 light years. I have not been able to find a previous amateur image of this object.

This bi-polar PN has two red (hydrogen) ansae that protrude from a cyan (oxygen) nebula structure. Studies have concluded that such ansae are typically generated by fast rotating close-binary central star systems, and indeed this PN has one of the shortest period orbits at just over 3 hours. Other similar PN include NGC 6210 and NGC 6309.

Because the structure of this PN is not quite symmetric, it is likely that a third star may be part of the central star system.

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.
