Integrated Flux Nebula

Astronomy Picture of the Day (http://antwrp.gsfc.nasa.gov/apod/) for Monday 12th May shows an interesting image of M81/M82 area of the sky with a little known foreground milky way nebula smudging across the sky.


If you follow this link: http://www.galaxyimages.com/UNP1.html you can read all about the Unexplored Nebulae Project and the Integrated Flux Nebula. It's fascinating and shows how significant a contribution "amateurs" can make to modern astronomy.

In a nutshell (and this is very simplified, you should read about it on the link above) the IFN are high-latitude nebulae "high above the plane of the Milky Way, many around the North Galactic Pole and Polaris...reflecting and being ionized by the integrated flux of all the stars in the Milky Way Galaxy" to quote Steve Mandel.
