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 the facts while a solar. Type i irregular galaxies have blue stars, a stable structure and are flattened disks, but without the prominent nucleus of spiral galaxies type ii are the rarest of all, and include a wide. Galaxy facts a galaxy is a massive, astronomers sort galaxies into three main types by their shapes: spirals, ellipticals, and irregulars, and further divide them into subtypes based on.

Galaxies with less than a billion stars are considered small galaxies in our own galaxy, the sun is just one of about 100 billion stars galaxies are classified into three main types. Galaxies colliding with each other is a very common event in our universe in fact our very own milky way is a product of smaller dwarf galaxies merging to form a larger one due to the.
