Galaxy Types - Science@NASA
Scientists sometimes categorize galaxies based on their shapes and physical features. Other classifications organize galaxies by the activity in their central regions – powered by a supersized black hole – and the angle at which we view them.
Galaxy - Elliptical, Spiral, Irregular | Britannica
5 days ago · Each of these classes is subclassified into three types according to the size of the nucleus and the degree to which the spiral arms are coiled. The three types are denoted with the lowercase letters a, b, and c. There also exist galaxies …
Types of Galaxies - Spiral, Elliptical & Irregular Galaxies - Space Facts
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. It uses the three main types: Spiral; Elliptical; Irregular; then further breaks them down by specific characteristics (openness of spirals, size and extent of bars, size of galactic bulges).
Types of Galaxies | Pictures, Facts, and Information - AstroBackyard
There are four distinct types of galaxies in the universe, elliptical, spiral, barred spiral, and irregular. Although these are the four main types, there are various types of galaxies and the way in which they are classified is by their shape.

Dec 22, 2022 · In total, there are four main groups of galaxies: spiral, elliptical, irregular, and peculiar. Each of these types of galaxies have their own unique features and history, adding more beauty to an already stunning universe. Hubble image of …
The Different Types Of Galaxies
As discussed in the section on galaxy classifications, Hubble found four distinct types of galaxies: elliptical, spiral, spiral barred, and irregular. Although there are different types, we also learned that each galaxy contains the same elements, but these are arranged differently for each type.

Jan 19, 2022 · A galaxy is a huge collection of gas, dust, and billions of stars all held together by gravity. All galaxies are made up of these same things. However, they come in many different shapes and sizes. Here are a few types of galaxies: Spiral galaxies look like giant pinwheels. The arms of the pinwheel are made up of stars and lots of gas and dust.
How Many Types of Galaxies Are There? | My Space Museum
Galaxies, the cosmic metropolises of the universe, display three primary types: Spirals, Ellipticals, and Irregulars. Spirals like the Andromeda Galaxy boast majestic arms spiraling from a central nucleus, featuring vibrant star-forming regions.
Types of Galaxies | Astronomy explained - naturalsciences.ch
These three classes - elliptical, spiral and irregular - span several subclasses that further differentiate the shape of galaxies. Elliptical galaxies (E) are structureless, elliptical galaxies whose brightness decreases from the inside to the outside. The ellipses are divided into subclasses from circular (E0) to strongly elliptical (E7).
Types of Galaxies | Astronomy - Lumen Learning
Our own Galaxy and the Andromeda galaxy are typical, large spiral galaxies. They consist of a central bulge, a halo, a disk, and spiral arms. Interstellar material is usually spread throughout the disks of spiral galaxies.
