It has intense ultraviolet radiation from the luminous, massive stars (Howell). One of the brightest regions found inside the Triangulum Galaxy is the NCG 604. It is about 1,500 light years away, which makes it one of the largest discovered in the Local Group. One of the brightest regions found inside the Triangulum Galaxy is the NCG 604. It is about 1,500 light years away, which makes it one of the largest discovered in the Local Group. It has about 200 blue stars and about 100 times bigger than Orion Nebula, but is the smallest spiral galaxy in the Local Group. It is believed that there are over 40 billion stars in the M33 and it is currently moving closer to the Andromeda (M31). It is believed that these two have tidally interacted in the past (“Triangulum Galaxy – Messier 33”). Some believe that there was a supermassive black hole in the center of M33 but it does not. The black hole is near the core of the
