Identifying the King Cobra in Messier 67
o

oooo
- On the left – Identifying the King Cobra shape in Messier 67 requires looking at the curving arcs of stars along the outer edges of the cluster, the top-most edge of the main cluster forms a sharper point, giving the illusion of a head raised and ready to strike.
o - On the right – I rotated the photo of Messier 67 and trimmed it to zoom in on the best part, then I hand-traced the shape of a King Cobra.
