A nearby galaxy is shining with star formation in a new image from the Hubble Space Telescope.
The spiral galaxy Messier 33 (M33), also known as the Triangulum Galaxy, is the third-largest member of the Local Group of galaxies, after the Andromeda galaxy (M31) and our own Milky Way. Measuring only 60,000 light-years across, M33 is about half the size of the Milky Way.
