Kuzey Amerika Bulutsusu (NGC 7000 veya Caldwell 20), Kuğu takımyıldızı yönünde Deneb (kuğunun kuyruğundaki parlak yıldız) yakınındaki bir salma bulutsusu. Bulutsu, çarpıcı bir şekilde Meksika körfezi ile birlikte tam olarak Kuzey Amerika kıtasını andırmaktadır. William Herschel tarafından 24 Ekim 1786 yılında keşfedilmiştir.

Kuzey Amerika Bulutsusu gökyüzünde dört dolunay boyutu alan kaplayacak kadar büyükse de, yüzey parlaklığının çok düşük olması nedeniyle çıplak gözle görülemez. Dürbün ve teleskop ile ancak iyi gözlem koşullarında puslu bir şekilde gözlemlenebilir. Ancak, UHC filtre kullanılarak ışığın istenmeyen dalgaboylarının filtrelenmesiyle görülebilir. Özellikle kırmızı renkli (hidrojen Hα salma çizgisi) sadece fotoğraflarda görülebilmektedir.

Kuzey Amerika Bulutsusu ve Pelikan Bulutsusu (IC 5070) aslında aynı iyonize hidrojen (H II bölgesi) yıldızlararası bulutun birer parçalarıdır. Özellikle Orta Amerika ve Meksika gibi görünen parlak kısımlar, aslında sıcak bir gaz ve toz yatağı olup, yeni oluşmuş yıldızların meydana getirdiği Kuğu Duvarı'nı da içermektedir.

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.
