NGC 281, famously known as the Pacman Nebula, beckons astronomers and stargazers alike with its mesmerizing beauty and intriguing cosmic secrets. Situated approximately 9,200 light-years away in the constellation Cassiopeia, this celestial wonder never fails to captivate our imagination.Formation and StructureThe Pacman Nebula owes its distinctive name to the uncanny resemblance it bears to the iconic video game character. It's a sprawling emission nebula, a colossal cloud of gas and dust, intricately sculpted by the forces of the universe. Within its folds lie newborn stars, radiating intense ultraviolet light that causes the surrounding gas to glow in vibrant hues of red and pink.Stellar NurseriesNGC 281 serves as a stellar nursery, birthing stars at a remarkable rate. Deep within its core, the densest regions cradle embryonic stars, shrouded in the cocoon of their birth clouds. These young stars, known as T Tauri stars, are still in their infancy, surrounded by rotating disks of dust and gas from which planets may one day 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.
