Spiral Galaxies

What’s unusual about this Spiral Galaxy?

Barred-Spiral Galaxies

What kind of Galaxy is this?

Elliptical Galaxies

At the core of the Virgo Cluster lie the three Giant Elliptical galaxies M84, M86 and M87. These galaxies probably formed from the merger of many smaller galaxies and are much more massive than our own Milky Way Galaxy.

“Dwarf Galaxies” in our neighborhood… (The “Local Group” of Galaxies)

What kind of Galaxies are these? “Lenticular” Galaxies

Meet our Nearest (Southern) Galactic Neighbors…

What kind of Galaxies are these? “Irregular” Galaxies

Galactic Collisions!
