Part 2 Answer Key
... Star Clusters are multiple star systems bound together by the force of gravity. Star Clusters can be divided into two main groups. One group is called Globular Clusters. They contain many stars and gravity holds them tightly together. They swarm just outside the galaxy and form a halo or bulge. We k ...

Corvus (constellation)
Corvus is a small constellation in the Southern Celestial Hemisphere. Its name comes from the Latin word ""raven"" or ""crow"". It includes only 11 stars with brighter than 4.02 magnitudes. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it remains one of the 88 modern constellations. The four brightest stars, Gamma, Delta, Epsilon, and Beta Corvi from a distinctive quadrilateral in the night sky. The young star Eta Corvi has been found to have two debris disks.
