- 4. The relative abundance of elements heavier than helium in a star or galaxy.
- 6. An expansive spherical region that encircles the disk of a galaxy.
- 8. Expansive clouds of interstellar dust and gas where stars are born.
- 10. A type of star cluster that is a nearly spherical collection of thousands to millions of stars, held together by mutual gravitational attraction.

Down
- 1. A galaxy that is our nearest large galactic neighbor and holds over 400 star clusters.
- 3. A well known star cluster located in the Taurus constellation.
- 5. A type of observation method that is the most sound for identifying embedded clusters.
- 7. Irregular fluid motion characterized by vortices and eddies, playing a significant role in the formation and structure of interstellar gas clouds.
