M33

M33, also known as the Triangulum Galaxy, is a spiral galaxy located about 3 million light-years away from Earth. It is part of the Local Group of galaxies, which includes the Milky Way and the Andromeda Galaxy. M33 is characterized by its prominent spiral arms rich in stars, gas, and dust, making it a site of active star formation. It has a diameter of roughly 60,000 light-years, making it smaller than the Milky Way. M33 provides valuable insights into galaxy formation and evolution due to its relative proximity and well-defined structure.
