| Constellation - Coordinates | Puppis (Pup) - 07h35min -46°56' |
| Description | Cometary
globules are isolated, relatively small clouds of gas and dust within the
Milky Way. This example is very, very dim and about 1300 light years
distant. The 'head', which is some 1.5 light years in diameter, seems
about to devour the edge-on spiral galaxy PGC 21338 (mag 14.4), which in
reality is hundreds of millions of light years away, far beyond CG
4.
