Object description
| Object type | Emission nebula "The North America Nebula" |
| Constellation | Swan |
| Visual magnitude | 4 |
| Distance | 2200 light years |
| Diameter | 56 x 47 light years |
| Dimension seen from Earth | Approximately 120 x 100 arc minutes |
| In the swan's tail is the nebula NGC7000, nicknamed the North America Nebula because of its resemblance to the North American continent. We thus see appearing at the bottom of the image, to the right, the State of Florida and the Gulf of Mexico. We also see California on the left. The right side looks strangely like the east coast of North America to Quebec! With a clear and dark sky, you can see the nebula through binoculars, but it is best to admire it in long exposure photographs like in this very beautiful image. The North American Nebula is part of an interstellar cloud of ionized hydrogen (HII region). Between the earth and the nebula is a band of interstellar dust that absorbs some of the light from the stars and the nebula behind it, which determines the shape we see. |
