|  Newly forming stars in Galaxy M33. Hubble Space Telescope's View of Starbirth. Dec 7, 2003 The Hubble Space Telescope took this incredible photograph of nebula NGC 604, which is a huge area of newly forming stars in Galaxy M33. The area is similar to the star forming region in the Orion Nebula, but it's 100 times larger. The most massive stars in the nebula are 120 times the mass of the Sun and their surface temperatures exceed 40,000 degrees Kelvin. Intense ultraviolet radiation floods out of these stars, which lights up the surrounding gas. NGC 604 is 2.7 million light-years away in the constellation Triangulum. Go To Print Article
