Bubble N107 – false colour multiwavelength image. The 24 μm continuum (red) is dominated by the emission of very small dust grains heated by a nearby massive star. The 8 μm continuum (green) is dominated by the emission of PAHs, large molecules found within molecular clouds. The CO line (blue) is integrated over the radial velocities between 38.5 km s^-1 and 47.6 km s^-1 and traces the cold gas of molecular clouds. The distinct red-green structure seen in the lower-left in the direction of the bubble’s opening is probably not related to the bubble, since the radial velocity of the associated molecular material (≈60 km s^-1) differs significantly from the radial velocity of the N107 complex (≈43 km s^-1).
