Messier 81 (Bode's Galaxy or NGC 3031) and Messier 82 (Cigar Galaxy or NGC 3034) are respectively spiral and starburst galaxy about 12 million light-years away in the constellation Ursa Major.This couple is seen through the faint glow of an Integrated Flux Nebulae (or IFN), which are high galactic latitude nebulae that are illuminated not by a single star (like the most nebulae in the equatorial plane of our Galaxy), but by the energy from the integrated flux of all the stars in the Milky Way.These little studied nebulae clouds are important component of the Interstellar Medium. They are composed of dust particles, hydrogen, carbon monoxide and other elements.
