Galaxies: Island Universes

Galaxies, by definition, are massive, gravitationally bound systems that consist of stars, stellar remnants, and a mixture of gas, dust, and dark matter. There are more than 170 billion galaxies in the observable universe. Most are 1,000 to 100,000 parsecs (30.9 trillion kilometers) in diameter. The size of galaxies range anywhere from 10 million stars in the smaller end of the spectrum to 100 million stars at the larger end. It is believed that many, if not all, galaxies are centralized with super massive black holes. Galaxies are generally categorized based on their visual appearance. Learn about the different types while journeying across the universe and observing what galaxies look like! The concept of dark matter will be discussed and how it relates to the rotation of galaxies.
