PK 104-29.1 (Jones 1)

Jones 1 est une nébuleuse planétaire située dans la constellation de Pégase. Elle a été découverte par Rebecca Jones en 1941 sur des plaques photographiques.
D'une luminosité totale de 12,7 mag, sa luminosité surfacique n'est que de 16,6 mag.

La nébuleuse est déjà âgée de 37 000 ans. Avec une extension de 5,3' x 5,3', la taille de la nébuleuse est de taille réelle est d'environ 3,5 années-lumière.

Celle-ci brille presque exclusivement dans la lumière de l'oxygène doublement ionisé. Une zone Ha-Alpha n'est visible que dans un filament de nébuleuse au sud de PK 104 -29.1.

L'étoile centrale 3UC241-308979 de 16,65mag est l'étoile turquoise du groupe d'étoiles au centre de la nébuleuse. La distance de l'étoile centrale est de 808 pc ce qui correspond à 2634 années-lumière.

Tout près de PK 104 -29.1 se trouve également un quasar brillant, [VV2006] J233604.7+302355, qui a un décalage vers le rouge de z=2,094, ce qui correspond à une distance de plus de 9 milliards d'années-lumière avec une constante de Hubble de 74,3 km/s/MPc.

Avec 17,7 Rmag, c'est le plus brillant de la douzaine de quasars présents sur cette image.

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.
