Sh2-140

This HII hydrogen emission nebula is located about 3000 light years away in the constellation of Cepheus at a declination of +63 degrees. The brightest portion of the nebula seen here is about 9 arc-minutes in our apparent view, which corresponds to a width of about 8 light years.

The image includes a small star cluster (Pismis-Moreno 1) and a hint of blue reflection nebulae. The cloud pillars of the emission nebula are pointed towards the cluster, sculpted by the stellar winds and radiation of the bright stars. A number of Herbig-Haro objects are embedded in the central section of the nebula but are not easily seen in this 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.
