Melotte-15 is the star cluster at the heart of the Heart Nebula. It is an OB association of very young hot blue supergiant stars that is only 1.5 million years old. Fierce stellar winds from this cluster have blown the enormous bubble within the parent HII nebula that is the heart nebula. The winds have also sculpted the dust clouds within which other stars are forming into interesting columns and shapes, analogous to the Pillars of Creation in the Eagle Nebula

IC1805 Nebula is in the constellation Cassiopeia. In the central part of the cloud shines Melotte 15, a cluster of giant stars, young and very hot. The ultraviolet radiation from massive stars sculpted this fantastic gas column. Is commonly identified with the name of Melotte 15. The age of the cluster is estimated at a million and a half years and its distance from Earth, about 7,500 light years.

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.
