Click image for detailed view

Bode’s Galaxy (M81) and the Cigar Galaxy (M82) are a pair of galaxies located in the constellation, Ursa Major. Bode’s is a spiral galaxy while the Cigar Galaxy is an irregular galaxy , both approximately 11.8 milion light-years away from earth.

Bode’s Galaxy has a diameter of 90,000 light-years, which is half the size of our own Milky Way Galaxy, and both galaxies are rich in hydrogen-alpha gases.

These two galaxies have a gravitational lock on each other which affects their shape and composition on each other. One of the interesting parts of this image is the Integrated Flux Nebulal (IFN) that is an extremely faint and difficult to photograph nebula.
