About this Image

This chaotic object situated in the constellation Cepheus in a distance of 3000 light years is an extended area filled with gas and dust that is energized by a young open cluster of stars (above top of image).
The stellar wind is shaping bizzare pillars and towers of dust embedded in glowing ionized gas clouds, mainly hydrogen (red) and oxygen (blueish).

The whole object extends far out of this imaged area and incorporates NGC7822, as whole also cataloged as SH2-171. The central part of Cederblad 214 is shown here in this high resolution image.
North is up.
