Iris in the dust

The Iris Nebula, most frequently referred to by NGC 7023. It is located in the constellation of Cepheus. NGC 7023 is a combination of a reflection nebula and an open cluster of stars. The shape of the reflection nebula glowing in blue resembles the plant Iris, hence the name of the object. The distance of the complex is about 1300-1400 light-years from Earth, the reflection part has a diameter of about 6 light-years. The blue light which is being reflected by the nebula is coming from the young hot star at the center of the bubble. The bubble was created by the star itself, sweeping the interstellar dust and gases out from its vicinity by its intense stellar winds. The dust cloud consists of very fine dust of solid particles, gases and simple molecules. Although the density of the cloud is rather low, it is still opaque in the visible wavelengths because of its vast proportions. It blocks the light coming from stars and other kinds of objects behind it.

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.
