Galaxy Types: A Cosmic Classification

Understanding the diverse shapes and structures of galaxies across the universe.

Spiral Galaxy

Spiral Galaxies

Characterized by their spiral arms that extend from a central bulge, spiral galaxies are home to active star formation. Our own Milky Way is a prime example.

Elliptical Galaxy

Elliptical Galaxies

These galaxies are smooth, featureless, and range from nearly spherical to highly elongated. They typically contain older stars and have little gas or dust.

Irregular Galaxy

Irregular Galaxies

Lacking a distinct regular shape, these galaxies often result from gravitational disturbances or collisions. They can be rich in gas and dust, fostering new stars.

Lenticular Galaxy

Lenticular Galaxies

Positioned between spirals and ellipticals, lenticular galaxies have a central bulge and a disk but lack significant spiral arms. They contain mostly older stars.
