Triangulum Galaxy

Located in the constellation Triangulum, the M 33 galaxy is one of the most fascinating members of the Local Group, along with the Milky Way and the Andromeda Galaxy. It is about 2.7 million light-years away from Earth and spans over 60,000 light-years in diameter. Also known as the "Triangulum Galaxy", M 33 is a spiral galaxy seen nearly face-on, characterized by massive star-forming regions. Among these, NGC 604 stands out as one of the largest HII nebulae known in the Local Group: a true cosmic factory where massive and bright stars are born.
