The interesting structure in the image is a giant area of ionized hydrogen, it's caused to glow by the intense ultraviolet radiation from the massive stars of the Melotte 15 star cluster.
Dust and gas clouds are twisted by the pressure of the intense radiation, the solar wind.
This formation is estimated to be 7,500 light years away from Earth, North is up.
