The Seahorse Nebula aka Barnard 150

Located in the constellation of Cepheus, the Seahorse is a dark molecular cloud of dust. It is visible because of the ambient light from thousands of stars/suns behind it. It is located about 1,200 light years from us in the elliptical plane of our Milk Way galaxy.

Pixinsight, the image processing application, detected 20,121 suns in this image. From our distance it is about the width of two full moons in the sky. There are three distinct dark cores located in the Seahorse which are star factories. This is stardust. As time goes on, hundreds of new suns will form in these regions. The astronomer Edward Barnard discovered this nebula in 1919, but the Seahorse is ancient.

The Milky Way is alive and continues to form.

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.
