IC 1848 – SOUL NEBULA (DETAIL)
The Soul Nebula is an emission nebula located in the constellation Cassiopeia, 7500 light-years from Earth.
It is known by the acronym IC1848 or W4 and is paired with an equally famous nebula, the Heart Nebula.
both are very large for about 300 light years.

This is a very large HII region, whose distance is estimated at 7600 light years from us; its gas is illuminated by the stars of some clusters and associations of nearby stars, among which Cr 33 and Cr 34 stand out, two very large but concentrationless open clusters, formed by giant blue stars born from the gases of the nebula. The light is then re-emitted from the nebula in the red color typical of hydrogen H-alpha emission lines. Star formation is very active inside 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.
