A faint Planetary Nebula : Abell 36

This time we present you a planetary Nebula rather unimagined which like almost all the objects of the Caldwell catalog are quite diffuse.

Abell 36 (PK 318+41.1)

The magnificent gaseous shroud of a dying solar star, the planetary nebula Abell 36, is only 800 light years from the constellation Virgo. At this distance, it extends over 1.5 light-years and has a low polygon magnitude 13. By raising its outer layers, the central star of the nebula contracts and becomes warmer, evolving into a final phase of a white dwarf. In fact, in Abell 36, it is estimated that the central star has a surface temperature of more than 73,000 K, compared to the current temperature of 6,000 K of the Sun. As a result, the intensely hot star is much brighter in ultraviolet light, compared to its visual appearance here. Invisible ultraviolet light ionizes the hydrogen and oxygen atoms in the nebula and finally feeds the beautiful glow of visible light

The morphokinematical analysis shows that Abell36 consists of an inner spheroid and two bright point-symmetric arcs.

The formation of Abell36 and DeHt2 requires several ejection events including collimated bipolar outflows that probably are younger than and have disrupted the main shell.

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.
