Description:

NGC 4236 is a barred spiral galaxy located in the constellation Draco, approximately 11.7 million light-years away from Earth. It is a member of the M81 Group, which is a nearby group of galaxies that also includes the well-known Messier 81 (Bode’s Galaxy) and Messier 82 (the Cigar Galaxy).

This galaxy is classified as SB(s)dm, meaning it has a loosely wound spiral structure with a central bar but lacks a prominent bulge. Its structure is quite diffuse and irregular.

NGC 4236 stretches about 100,000 light-years across, roughly the size of the Milky Way, and is rich in gas and dust, making it an active site for star formation, particularly in its outer arms.

Although it doesn't shine as brightly as some other members of its galaxy group, NGC 4236 plays an important role in helping astronomers understand galactic evolution and the properties of low surface brightness galaxies in the local universe.
