Abell 2 (Gary Imm)

Celestial hemisphere: Northern · Constellation: Cassiopeia (Cas) · Contains: PGC 137160 · PK122-04.1

Abell 2

This object is a planetary nebula located 13,000 light years away in the constellation of Cassiopeia at a declination of +58 degrees. This PN spans 0.5 arc-minutes in our apparent view, which corresponds to a diameter of 2 light years.

Not much has been written about this object. The central star is barely visible. The nebula structure is similar to a smaller version of M97 (Owl Nebula) – round, primarily oxygen, and two dark circular voids in the inner region which are likely caused by bi-polar jets from the central star. Several PN appear like this, is a class that I refer to as the Owl Texture. Typically with this texture, one void is slight darker than the other, the darker void being pointed more towards our line of sight.

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.
