Sh2-180 (John Bozeman)

Sh2-180

Sh2 -180 is a visible emission nebula in the Cassiopeia constellation. It is located in the northwestern part of the constellation, about 2 ° to ENE of the star κ Cassiopeiae. Being at a distance of about 6100 parsecs (about 19900 light years), Sh2-180 finds itself on the Swan's Arm, beyond the large complexes linked to the OB associations visible in Cassiopeia, which almost all fall into the innermost Arm of Perseus. LS I +62 139, a main sequence blue star with spectral class O7.5V, is believed to be responsible for the ionization of its gases; estimates of its distance indicate for this star a value of 5150 ± 1300 parsecs, that although it is smaller than the estimate of 6100 parsecs, it is not much at odds with it given the considerable margin of uncertainty. Beyond these data, the nebula seems to have been little studied and its filamentous appearance, which resembles that of a supernova remnant, raises other questions.

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.
