Abell 30 is a small (127 arc seconds) extremely faint planetary nebula located approximately 5,500 light-years away in the constellation of Cancer. Abell 30 is one of just three known nebulae called born-again planetary nebulae. Very rarely, nuclear reactions within the vicinity of a white dwarf can heat the gases to such high temperatures that the tiny star briefly becomes a red giant once more. This is a very brief phase, lasting a mere 20 years or so. The original nebula is estimated to be around 12,500 years old (which in itself is very brief in astronomical terms). The tiny features in the centre of the bubble are evidence of this re-birth. They are most probably comprised of helium and carbon-rich materials and were ejected around 850 years ago.

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.
