Estas nubes de polvo y de gas interestelar han florecido a 1.300 años luz de distancia, en los fértiles campos de estrellas de la constelación Cefeo . Pero NGC 7023 , a veces llamada la nebulosa Iris, no es la única nebulosa que evoca las imágenes de flores .Esta perspectiva telescópica muestra la gama de colores y de simetrías de la nebulosa Iris con un detalle impresionante. Dentro de Iris , el material nebular polvoriento rodea una estrella joven y caliente. El color dominante de la nebulosa de reflexión más brillante es el azul, característico de los granos de polvo que reflejan la luz estelar. Los filamentos centrales de las nubes polvorientos brillan con una fotoluminiscencia tenue y rojiza cuando algunos granos de polvo convierten la radiación ultravioleta invisible de las estrellas en luz roja visible. Las observaciones en infrarrojo indican que esta nebulosa podría contener moléculas complejas de carbono conocidas como PAHs . Los bonitos pétalos azules de la nebulosa Iris abarcan unos seis años luz.

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.
