Variety of Galaxies

Using by powerful telescopes, in most galaxies only detected mixed light of all the stars, but show the closest individual stars. Galaxies come in a variety of ways. In 1930 Hubble classified galaxies into elliptical, spirals and irregulars, the first two being the most frequent.

Elliptical galaxies

Some galaxies have a globular shape, with a bright nucleus. They called ellipticals, contain a large population of old stars, usually little gas and dust,and some newly formed stars. Elliptical galaxies have a variety of sizes,

The variety of galaxies

The massive stellar systems - galaxies, distant and mysterious, one of the most exciting and most studied objects in astronomy today. In this article we look at the types of galaxies, their main differences and peculiarities. Galaxies in the universe is not similar to each other. Some are round and elliptical shape, while others are observed in the form of swirling spirals. In the 20-xx years of the twentieth century, Edwin Habll in their work proposed to classify the galaxies into three basic types: elliptical, spiral and irregular, denoted, respectively, E, S and Irr.
