M33 is a magnitude 6.27 spiral galaxy lying about 3 million light-years away in the constellation Triangulum. It was cataloged by Charles Messier in 1784, but was possibly discovered by Giovanni Batista Hodierna in 1654. The Triangulum Galaxy is known to contain many huge H-II regions - one being the largest known.
