BoBn 1

This Astrobin Debut Object is an extragalactic planetary nebula located 65,000 light years away in the constellation of Cetus at a declination of -14 degrees. This magnitude 16.4 PN spans only 3 arc-seconds in our apparent view, which corresponds to a diameter of 1 light year. Many times I am surprised to find that an object has not appeared on Astrobin before, but I am not surprised in this case.

The discovery of this stellar PN was announced in a 1977 paper by Dr. Boeshaar and Dr. Bond. This PN is believed to have originated outside of the Milky Way galaxy, in the Sagittarius Dwarf Spheroidal Galaxy. The object is now within our Milky Way, in the former galaxy’s stellar stream.

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.
