The Prawn Nebula (IC 4628) is an emission nebula and star-forming region located in the constellation of Scorpius. Due to the presence of hydrogen-rich gas clouds, it glows in a reddish hue when high energy radiation from massive stars ionize the interstellar gas cloud. Beside the Prawn Nebula is a bright star cluster known as the Northern Jewel Box or False Comet. Designated as NGC 6231, it appears to leave a trail of stars leading to IC 4628. The cropped images show close ups of NGC 6231 (left) and IC 4628 (right).
