In the heart of IC1805 from a Bortle9 area

The Heart Nebula, also known as IC 1805, is an emission nebula located in the constellation Cassiopeia, approximately 7,500 light-years away from Earth. It spans about 150 light-years across and is characterized by its vivid red hue, caused by the ionized hydrogen gas within it. At the center of the Heart Nebula lies a cluster of young, massive stars known as Melotte 15. These stars, formed from the surrounding gas and dust, emit intense ultraviolet radiation that ionizes the hydrogen gas, causing it to glow. This process creates the striking emission nebula seen in images of IC 1805. The central region of the nebula is particularly dense with gas and dust, giving rise to intricate structures and pillars sculpted by the radiation and stellar winds from the young stars. These pillars, reminiscent of those found in other famous nebulae such as the Eagle Nebula, serve as nurseries for new stars, where the gravitational collapse of dense regions leads to the formation of protostars. In addition to the stellar nursery, the central portion of the Heart Nebula exhibits intricate filaments and knots of gas and dust, illuminated by the energetic radiation from the young stars. These features contribute to the nebula's overall complexity and beauty, captured in stunning detail by telescopes and astrophotographers. Overall, the Heart Nebula, with its central cluster of young stars and intricate structures, stands as a testament to the ongoing process of star formation and the beauty of the cosmos.

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.
