Sh2-132

Sh2-132 is located at a distance of almost 3200 parsecs (almost 10400 light years ), thus placing it within the Perseus Arm , in the Cepheus region OB1, a large and bright OB association . The stars responsible for the ionization of its gases are very hot and massive; in particular, two Wolf-Rayet stars , known with the abbreviations HD 211564 and HD 211853 (the latter also having the abbreviation WR 153), as well as a star of spectral class O8.5V and about ten stars of class B. Around the class O star and one of the Wolf-Rayet stars extends a clearly visible bubble in the band of radio waves , identified with the acronym Shell B , probably originating from the stellar wind of the two massive stars. A similar but smaller structure, Shell A , hosts a class K star near its center. It is believed that chain star formation processes took place in the nebula in the past; currently these processes appear to be suspended, since there is no trace of recent activity. Nine sources of infrared radiation and a maser with H 2 O emissions have been identified in the direction of the nebula .

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.
