NGC 7000 es una nebulosa de emisión en la constelación de Cygnus, situada cerca de Deneb (α Cygni), que también recibe el nombre de Nebulosa Norteamérica. La región central oscura se denomina El Golfo de México, ya que en algunas placas astronómicas de hace muchos años se parecía a esa región de la Tierra.

NGC 7000 es una nebulosa grande que cubre un área equivalente a la luna llena, pero su bajo brillo superficial hace que normalmente no sea visible a simple vista (sin embargo, en una noche oscura y con ayuda de un filtro UHC puede verse sin ayuda óptica). NGC 7000 y la cercana Nebulosa Pelícano (IC 5070) forman parte de la misma nube interestelar de hidrógeno ionizado (región HII). El área oscura del centro es una región muy densa de material interestelar que se encuentra delante de la nebulosa y que absorbe la luz de la misma, dando al conjunto su forma característica.

No se conoce con precisión la distancia que nos separa de NGC 7000, ni la estrella responsable de la ionización del hidrógeno que produce la emisión de luz. Si, como algunas fuentes señalan, Deneb es la estrella que ilumina la nebulosa, la distancia de NGC 7000 a la Tierra sería del orden de 1800 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.
