Sagittarius Dwarf Spheroidal Galaxy

The Sagittarius Dwarf Spheroidal Galaxy is a small, faint galaxy located near our Milky Way. It contains stars, gas, and dark matter, but is much less luminous and smaller than our galaxy. Over time, it is gradually being pulled apart and absorbed by the Milky Way due to gravitational forces. This process, called tidal disruption, causes the Sagittarius Dwarf to leave behind streams of stars that orbit the larger galaxy. Its study helps astronomers understand galaxy interactions, evolution, and the dynamic environment of our local cosmic neighborhood.
