The structure formed by as assembly of thousands of millions of stars together with gas and dust. Our Galaxy, the Milky Way, is a spiral galaxy. Galaxies may be described as elliptical, irregular or spiral. Our Galaxy is just one among many millions.

A vast collection of stars, gas, and dust, typically 10,000 to 100,000 light-years in diameter and containing billions of stars (from galaxias kuklos, Greek for “circle of milk,” originally used to describe our own Milky Way).

A cluster of stars, dust, and gas held together by gravity.

A large collection of stars, gas, and dust held together by mutual gravitation.

A large-scale aggregate of stars (plus some gas and dust) held together by gravity. Galaxies have a spiral, elliptical, or irregular structure. Each contains, on average, 100 billion solar masses.

A galaxy is a large group of stars, dust, gas and dark matter held together by gravity. They vary in size with some containing millions of stars while others could contain as many as a trillion. They [..]

A large cluster of stars, gases, and dust held together by a shared gravitational pull.

A huge collection of stars – often many thousands of millions – and associated dust and gas. Galaxies are separated from each other by enormous stretches of empty space. They may be spiral in shape (like a Catherine-wheel), elliptical (like a football), or irregular. The galaxy we live in is referred to as the Galaxy (or sometimes, the Milky Way Ga [..]

A large community of stars in space, such as the Milky Way (our galaxy), to which the sun belongs. Galaxies contain billions of stars. Many are shaped in the form of a spiral.

The 'Milky Way'.

an enormous gravitationally bound assemblage of millions or billions of stars.

A very large system of stars, gas and dust isolated from its neighbors by an immensity of space; an "island universe".

A collection of stars, gas, and dust bound together by gravity. The smallest galaxies may contain only a few hundred thousand stars, while the largest galaxies have thousands of billions of stars. The Milky Way galaxy contains our solar system. Galaxies are classified or grouped by their shape. Round or oval galaxies are elliptical galaxies and tho [..]

Group of stars, dust and interstellar gas, isolated in space, whose cohesion is maintained by gravity.
