There are three main types of galaxies: spiral, elliptical, and irregular. Spiral galaxies are characterized by a spiral disk and bright center, and our Milky Way is a spiral galaxy. Elliptical galaxies vary in shape from round to elongated and have no bright center. Irregular galaxies have no discernible shape. Examples of each type are provided.

10. • Spiral galaxy are characterized by a distinct flattened spiral
disk with a bright centre called the nucleus
• Our own milky way is a spiral galaxy
• Spiral galaxies are represented by the letters ‘s’ and divided
into four subgroups
 There are
 So
 Sa
 Sb
 Sc


12. • Elliptical galaxies very in shape from completely
round to extremely elongated ovals
• Unlike spiral galaxies
• They have no bright nucleus at their centre
• Elliptical galaxies are divided into two subgroups
 E7
 E0
Eo galaxies nearly circular in a shape while E7
galaxies are extremely elongated or stretched out.

14. • A fourth type of galaxy is known as the irregular
galaxy
• These galaxies have no discernible shape or structure
• Irregular galaxies are divided into 2 parts
 IM
 I0
• The large and small magellanic clouds are examples of IM
class irregular galaxies
