A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way.

Galaxies are vast cosmic islands of stars, gas, dust, and dark matter held together by gravity. Hubble's keen eye has revealed intricate details of the shapes, structures, and histories of galaxies — whether...

Elliptical galaxies are usually comprised of very old stars or stars with low mass. Irregular galaxies are commonly small, and collectively they make up about a quarter of all the galaxies.

A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held But where is our solar system? It's a small part of the Milky Way Galaxy. A galaxy is a huge collection of...

Galaxy - Galaxy - Types of galaxies: Almost all current systems of galaxy classification are outgrowths of the initial scheme proposed by the American astronomer Edwin Hubble in 1926.

A composite image of the Messier 81 (M81) galaxy shows what astronomers call a "grand design" spiral galaxy, where each of its arms curls all the way down into its center.

Galaxies are defined as large groupings of stars, dust, and gas held together by gravity. They vary greatly in size and shape. Most of the objects we know of in space are contained within galaxies.

Most galaxies are billions of years old. In the links below you will find thousands of facts, figures, and images that will help you understand many things about galaxies in general and some specific types.

There are galaxies shaped like jellyfish, galaxies that consume other galaxies, and galaxies that seem to lack the dark matter that pervades the rest Here are the strangest galaxies in the universe.

Types of Galaxies. The most widely used classification scheme for galaxies is based on one devised by Edwin P. Hubble and further refined by astronomer Gerard de Vaucouleurs.

You are lying on a blanket on a clear summer night and gazing at the dark starry sky. You are trying to spot the big dipper, Andromeda, or maybe Orion.

Galaxies love to cluster together! Other clusters with hundreds to thousands of galaxies are called rich clusters. The low mass of a poor cluster prevents the cluster from holding onto its members tightly.

Most galaxies fall into well defined classifications, and are either spiral-shaped like the Milky Way, elliptical, or irregular shaped. However, there are some galaxies that defy all attempts at classification.

Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble...
