Description:

Most images of M81 and M82 will show the two galaxies and surrounding stars. But a deeper exposure and a more careful processing will reveal that far from being visualized against a nearly dark background, these galaxies are surrounded by huge clouds of dust. Well, they are not actually surrounded - the dust is much closer to us than the galaxies - it just happens to look that way. This very faint dust, unlike classic reflection nebulas - usually illuminated by neighboring stars - is actually illuminated by the glow of our own Milky Way. Steve Mandel named this nebulosity Integrated Flux Nebula.
