| Notes: |
CG 4 is a cometary globule in constellation Puppis. Cometary globules are
typically characterized by dusty heads and elongated tails. These features
cause cometary globules to have visual similarities to comets, but in
reality they are very much different. Globules are frequently the
birthplaces of stars, and many show very young stars in their heads. Further cometary globules, visible in the above image: CG 1, CG 2, CG 6, CG 13. North is to the left. |
