Galactic Soccerball, Abell 43 (PK036.0+17.1)

Galactic Soccerball, Abell 43 (PK036.0+17.6) is a small and dim planetary nebula in the constellation Ophiuchus. Although it is generally spherical, close inspection of the image will reveal a small distortion on the southeastern wall. What is of greater interest is the intricate filamentary structure which appears as a lace network around the spherical body of the nebula, and which looking similar to the structure of a soccer ball; hence, for its nickname ("Galactic Soccerball"). The central star in Abell 43, WD 1751+106, is quite unique due to the fact it is one of only four known examples of a hybrid PG1159 white dwarf star where hydrogen deficiency is not observed. Furthermore, the central star is a pulsating variable with six different pulsation modalities and which may be attributable to partially ionized carbon in its atmosphere. Abell 43 lie at a distance of about 6,850 light-years away and to span another 1.34 light-years across. The apparent size of the nebula is 80x74 arcseconds and a rather weak brightness (14.6m), although there is evidence that the visual magnitude is 16m.

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.
