Heart Nebula

The Heart Nebula (IC 1805) is an emission nebula located at an approximate distance of 7,500 light years from Earth, in the constellation Cassiopeia. It is also known as Sharpless 2-190 (Sh2-190) or the Running Dog Nebula because, when seen through a telescope, it looks a bit like a running dog. The nebula has an apparent magnitude of 18.3 and an absolute magnitude of 6.5. It is 150 arcminutes in size and known for its intensely red glowing gas and dark dust lanes forming a shape that resembles a heart symbol.

The Heart Nebula forms a famous complex known as the Heart and Soul with its smaller neighbour Westerhout 5, also known as the Soul Nebula, which lies just 2.5 degrees to the southeast.

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.
