What Causes The Formation Of A Spiral Galaxy? Spirals exist only among flattened or ‘disk’ galaxies. These galaxies are differentially rotating–that is, the time to complete a full rotation increases with distance from the center. Differential rotation causes any disturbance in the disk to wind up into a spiral form. Why do spiral galaxies form?
Where In The Milky Way Would You Be Most Likely To Find An Ionization Nebula? Where would you be most likely to find an ionization nebula? the orbits of stars in the galactic center. Where are most of the Milky Way’s globular clusters found? Where would you expect to find an ionization nebula in the
Could Life Exist In A Globular Cluster? Could life exist in a globular cluster? Brighter stars also live shorter lives, and since globular clusters are old, those stars have died out. [That means that the] predominant stars in globular clusters are faint, long-lived red dwarfs. Any potentially habitable planets they host would orbit nearby and
