The North American Nebula and Pelican Nebula

Click on picture for large view
Now directly overhead in my part of the world (Kansas City area), the North American Nebula and the Pelican Nebula are very rich areas of gas and dust in the Milky Way. The very dark area, right in the middle of the picture, is actually thick dust and gas in front of the nebulae, but it easily marks the similarity to Florida and the Gulf of Mexico. The nebula that looks like a pelican holding a fish in its beak is to the right of the North American Nebula. The bright star at upper right is Deneb, the brightest star in the constellation Cygnus, the swan. This is a very large area of sky. Four full moons would fit in the North American Nebula. From a dark sky site, away from the light pollution of the city, you can see it without optical aid, looking like a brighter region of the Milky Way. Binoculars improve the view, but a telescope has too much magnification not allowing you to make out the over all shape. It is best seen in wide view photographs.

  1. These Nebulae are the perfect example of order out of chaos. The reality of a fractal. i love to go to the desert and just stare out at the milky way or use a telescope to watch the Pliedaes or search for andromeda. Most of the backgrounds of my computer are all nebulae too. If you really look close enough, there is nothing more you need, than to look out at reality.

  2. Dear Pelican Products: I'm with you 100%. Fractals explain a lot of why we see what we see.

    I also love watching the night sky. Too bad so many people in the world never see the real thing.
