Comment: |
This huge area of emission nebulosity is famous because of its resemblance to the continent of North America. It is still not known which stars ionize the gas in the nebulosity and cause it to shine. Clouds of interstellar dust that absorb the light of stars and nebulosity behind them are responsible for the distinct shape of the nebula that we see. Star forming is still going on in the NGC7000, and some of the open clusters visible on the image are actually associated with the nebula. NGC7000 is some 50 ly across and 1600 ly distant. |
