Kyre Adept House Of Hives What are the three types of galaxies? learn about the three general types of galaxies: spiral, elliptical, and irregular. almost all current systems of galaxy classification are outgrowths of the initial scheme proposed by the american astronomer edwin hubble in 1926. Today, the basis for how we classify galaxies is still rooted in morphology, or how the galaxies appear. astronomers group galaxies by shape, and although there are many different types of galaxies, most fall into one of three categories: spiral, elliptical or irregular. Galaxies are immense collections of stars, gas, dust, and dark matter, held together by gravity. these cosmic structures vary significantly in size, ranging from dwarf galaxies with a few million stars to giant galaxies boasting trillions. We will discuss the evolution of galaxies in more detail in the evolution and distribution of galaxies, but let’s first see in a little more detail just what different galaxies are like.

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. it uses the three main types: spiral elliptical irregular. There are several schemes in use by which galaxies can be classified according to their morphologies, the most famous being the hubble sequence, devised by edwin hubble and later expanded by gérard de vaucouleurs and allan sandage. Galaxies are complex systems held together by gravity, but the shapes of different types of galaxies are a result of gravity along with rotation speed and time. Of the galaxies we have discovered, nearly all of them fall into one of the following three major categories. using slooh’s online telescope and integrated quest learning activities, you can capture your own images of each type of galaxy while learning more about them.
