Sh2-132 The Lion

Sh2-132 is a large and spectacular emission nebula visible in the constellation Cepheus. It is called "Lion Nebula" by the Anglo-Saxons because its shape resembles that of the king of the forest.
It is located on the southern edge of Cepheus, a short distance from the border with the Lizard, along the plane of the Milky Way within the Perseus Arm. Sh2-132 is located in the Cepheus OB1 region, a group of young, hot and massive stars of spectral class O and B (hence the name) that are found within a narrow region of space and that emit a large amount of ultraviolet light which ionizes the surrounding gas. Sh2-132 is located at an estimated distance between 10000 and 12000 LY from the Solar System. The stars responsible for the ionization of its gases are very hot and massive; in particular, two Wolf-Rayet stars were identified, known by the acronyms HD 211564 and HD 211853 (the latter also having the acronym WR 153), as well as a star of spectral class O8.5V and about ten stars of B. It is believed that chain star formation processes have taken place in the nebula in the past; currently these processes appear to be suspended, since there is no trace of recent activity.

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.
