NGC 6853 (Dumbbell Nebula)

My first capture of a planetary nebula was also the first to be discovered by Charles Messier in 1764. If the interstellar molecular clouds are similar to stellar nurseries M 27 is a stellar tomb, the tomb of stars like the sun.

Located about 1,200 light-years away from Earth, the Dumbbell Nebula is the final stage of any star that has between 0.8 and 8 solar masses. In the center of the nebula lies a white dwarf star, extremely hot, remnant of the expulsion of their own outer layers. The brightness of fuzzy due to high-energy radiation absorption of the central star and its reissue the visible spectrum, most of which are issued in a single spectral line centered on green double generated by ionization of oxygen.

Planetary nebulae are important objects in astronomy, who play a crucial role in the chemical evolution of galaxies, freeing the interstellar medium heavy metals and other products of nucleosynthesis of stars (such as carbon, nitrogen, oxygen and calcium), essential elements for the formation of life.

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.
