Exploring the Local Group: Journey Through Our Nearest Galaxies

Discover the fascinating composition of the Local Group, which includes about 30 galaxies, with the Milky Way being our home galaxy. Notable members include the Andromeda Galaxy, located 2 million light years away, and the Triangulum Galaxy, also known as the "Pinwheel Galaxy." This exploration includes the Sagittarius Dwarf Irregular Galaxy and the satellite Large and Small Magellanic Clouds. Positioned within the Virgo Supercluster, the Local Group offers insight into our place in the universe, featuring a diameter of 10 million light years and the gravitational center between galaxies.
