Attempt quiz on types of the Galaxies

Galaxies, vast systems of stars, gas, dust, and dark matter, come in several types based on their shapes and structures. The most common type is the spiral galaxy, characterized by a flat, rotating disk with spiral arms and a central bulge; the Milky Way and Andromeda are classic examples. Elliptical galaxies are more rounded or elongated in shape, with stars distributed more evenly and little gas or dust, making them mostly composed of older stars. Irregular galaxies lack a distinct shape or structure and often appear chaotic, sometimes as a result of gravitational interactions or collisions with other galaxies. Some galaxies also have barred structures, known as barred spiral galaxies, where a bar-shaped region of stars extends from the central bulge. Studying galaxy types helps astronomers understand the formation, evolution, and dynamics of the universe.
