Heart Nebula (IC 1805 / Sharpless 2-190)

Type: Emission nebula
Distance: Approximately 7,500 light years from Earth
Size: Roughly 200 light years across
Apparent size: 150 x 150 arc minutes
Apparent magnitude: 18.3
Age: About 1.5 million years
Constellation: Cassiopeia

The Heart Nebula, IC 1805 is a vast region of ionized hydrogen gas illuminated by young hot stars. At the heart (center) of the Heart Nebula is the star cluster Melotte 15, which contains several bright stars nearly 50 times the mass of our Sun. The intense radiation and stellar winds from these massive stars have carved out a cavity within the nebula, leading to its intricate structures and shapes.Details accurate to the best of my knowledge from research done in 2022.Very close to the Heart Nebula you will find the Soul Nebula. The Heart and Soul are often photographed together, in a single poetic image. My focal length won't allow me to do that, but maybe someday I'll create a mosaic.

This image needs some work. I hope to reprocess it someday soon.

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.
