Prawn Nebula: IC 4628 or GUM 56, sometimes also called Prawn Nebula, lies in the bend of the tail of Scorpius close to the brilliant Open Cluster NGC 6231(upper right corner in this image).
It is a highly dramatic nebular landscape, where massive young stars whip the surrounding matter to glow and compress. IC 4628 is in a distance of approx. 6000 LY and the image spans more than 300 LY. At closer inspection small globules can be detected, which are probably birthbeds of new stars not yet visible.
The Hi-Res version shows the richness in structure of this wonderful nebula even better.
