The Furnace Nebula, (sometimes called The Molten Nebula, or The Core) is a diffuse nebula located in M 82. The gases inside The Furnace Nebula, which are orange in color, are strangely hotter than the ones on the outside, which are grey and brown. This has granted The Furnace Nebula its name.

The Furnace Nebula is a hotspot for tourism, and the systems around it are generally more populated, with more wealth, as well.
