This image is false-color, meaning that same expanse, if viewed with a naked eye, would look far different from its current depiction. The colors represent light in infrared wavelengths, which is impossible for humans to see. The snapshot of the star cluster, called RCW 38, is among the sharpest and deepest images ever taken of the area. And it’s not that they caught this particular formation on a good hair (or rather, as good corona) day. A picture like this requires excellent photographic equipment, and this image is no exception.
