Sh2-140 in Cepheus

Sh2-140 is a star forming region located at about 2,900 light years from us in the constellation Cepheus. It is a beautiful and complex area and it features different kinds of structures, being the most prominent the hydrogen rich red clouds whose brightest structure is called Sh2-140, but also the dark dust clouds called LDN 1204 and 2304. In the middle there is a bright patch where the nearby young stars of cluster Pismis-Moreno-1 lighten the dust cloud nearby which sits in front of the red emission nebula. At the same time, these dark clouds block the light from the stars behind, which is seen by the reduced number of visible ones when compared with other areas. To be noticed the huge amount of stars in some areas; after all, we are looking to the Perseus arm of our Milky Way.

For me, one of the most interesting aspects of astronomy is mythology and Perseus' arm is certainly full of it. In Greek mythology, Cepheus was the king of Ethiopia and Cassiopeia his queen, a vain woman who once boasted she was more beautiful than the Nereids. The Nereids were sea nymphs and one of them was Poseidon's wife and that angered them. As a revenge, Poseidon sent Cetus, a sea monster, to ravage Cepheus lands. The oracles tell Cepheus the only way to prevent the impending disaster is to appease Poseidon by sacrificing their daughter. In desperation, Cepheus and Cassiopeia chain their daughter Andromeda to a rock for Cetus to find but luckily Perseus found her first, rescued her and defeated the monster. Later on, Perseus married Andromeda.

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.
