Detailed explanation-1: -Elliptical galaxies are shaped like spheres or cucumbers and contain old stars. Spiral galaxies have a central disk surrounded by spiraling arms and possess new stars. Irregular galaxies have no distinct shape and have both old and new stars.
Detailed explanation-2: -Our Milky Way Galaxy is a spiral galaxy. Some spiral galaxies are what we call “barred spirals” because the central bulge looks elongated – like a bar.
Detailed explanation-3: -Types of Galaxies Astronomers classify galaxies into three major categories: elliptical, spiral and irregular.
