 MBM 25 is a very diffuse molecular cloud that covers practically the whole image, extending in the constellation of the Lynx. These molecular clouds, also referred to as flow nebulae or galactic cirrus, are made up of gigantic dust and gas clouds of very low density (estimated to be between 25-50 particles per cubic centimeter), basically H and CO. They belong to our own galaxy but are located in high latitudes galactic, that is, above and below the main disk or galactic plane of the Milky Way. They are at distances of the order of thousands or tens of thousands of light years, much closer that distant galaxies that glows in the background (in this case, literally hundreds of them in the background) and whose vision and light filter us by getting in our visual. The dust disperses the blue light and reinforces a broad spectrum of red light, known effect known as "ERE "(Extended Red Emission). This sensibly attenuates blue glimpses and enhances the reds in visual images. These structures were first detected in 1984 by the infrared IRAS satellite and later studied in depth by Magnani, Blitz and Mundy constituting the MBM catalog.
