How do we know about galaxies
WebIrregular galaxies, including our neighbors Large and Small Magellanic Clouds, probably got their distorted shapes through gravitational interactions with other galaxies. Since ellipticals make up about 15% of known galaxies and irregulars are an additional 5%, mergers and interactions play an obvious role in the types of galaxies we see. WebIrregular galaxies are like stellar splotches in space, with little structure at all. Gazing skyward from our vantage point on and around Earth, there are clear signs that the Milky Way is a spiral galaxy. You can see one sign with the naked eye!
