Abell 33 (PK 238+34.1)

Another Abell... Abell 33 (PK238+34.1) in Rha-GOIII-BOIII Most stars with masses similar to that of our Sun will end their existence in the form of white dwarfs, small bodies, dense and hot at the same time, whose temperature gradually decreases over billions of years.During this final phase of their existence, they expel their atmosphere into the surrounding space, thereby generating planetary nebulae, i.e. envelopes of particularly bright and colorful gas around a bright, small stellar residue. The image reveals the remarkable circular contours of the planetary nebula Abell 33, located some 2,500 light-years from Earth. Such perfect sphericity is unusual for this type of object because often a factor disturbs this symmetry and the planetary nebula displays irregular contours. The rotation of the star or its belonging to a double or multiple star system can for example be a source of disturbance.The presence of a surprisingly bright star on the outer edge of the nebula creates a magnificent optical illusion. This is a totally fortuitous alignment: the star, named HD 83535, is actually in the foreground of the nebula, halfway or almost between Earth and Abell 33. At this precise place, it magnifies the image obtained. The combination of these two objects, HD 83535 on the one hand and Abell 33 on the other, forms a sparkling diamond ring.The remnant of the star that gave birth to Abell 33 is about to become a white dwarf. It appears as a milky pearl near the center of the nebula. It is still bright because its luminosity is greater than that of our own Sun and emits enough ultraviolet radiation to illuminate the ejected material.We prefer this version with Ha and OIII because the nebula has the good color blue-greenish for OIII.

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.
