Under dark sky conditions, M33 is just barely visible with the naked eye in the constellation Triangulum, just west of Andromeda and Pisces. Among the galaxy’s most distinctive features are ionized hydrogen clouds, also called H-II regions, which are massive regions of starbirth. Among Triangulum's most distinctive features is NGC 604, a region of starbirth so big that the Space Telescope Science Institute once described it as "monstrous."
