CHAPTER 4 : THE EYE OF CEPHEUS

The distant blue glow might be the next to be consumed by The Great Wave. As we neared the glow, its supporting structure's vastness became evident—a massive material pillar, seemingly timeless. This pedestal, birthed from the cosmic swell, felt intentionally crafted to cradle the Eye of Cepheus.
The light intensified, its deepening blue radiating calm serenity.

The all-seeing Eye of Cepheus, unafraid amidst chaos, made us wonder about the source of its tranquility.

KNOWLEDGE CHRONICLES :
Rayleigh's Blue Iris

The Iris Nebula glows the same blue as our sky, due to Rayleigh scattering. This phenomenon describes how light disperses when interacting with particles or obstacles. Shorter wavelengths like violet and blue scatter more effectively than longer ones like red. Thus, when light meets small particles or gas molecules, blue and violet scatter widely, while red wavelengths continue in their initial direction.

The Iris Nebula and our atmosphere perfectly showcase this effect.

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.
