Far-infrared image of Galactic Center At these long infrared wavelengths, the hottest dust glows blue, while the coldest is red.
The densely packed starfields at our galaxy's center are hidden behind dust clouds and only become visible in infrared light. In the near-infrared they begin to appear, but are reddened for much the same reason that sunlight turns red when filtered through a smoky cloud. The dense dust clouds begin to stand out at longer infrared wavelengths, taking on changing rainbows of color depending on which parts of the spectrum contribute to the image. The very coldest, densest dust will only start to glow at the very longest wavelengths of light, rendered in red in the far-infrared image in this sequence. Far-infrared: At these long infrared wavelengths, the hottest dust glows blue, while the coldest is red.

Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.
