Hubble Captures Galaxy in the Making

October 12, 2006: Images from NASA's Hubble Space Telescope have provided a dramatic glimpse of a large and massive galaxy under assembly by the merging of smaller, lighter galaxies.

Now, Hubble observations of the radio galaxy MRC 1138-262, nicknamed the "Spiderweb Galaxy" show dozens of star-forming satellite galaxies as individual clumpy features in the process of merging. Because the galaxy is 10.6 billion light-years away, astronomers are seeing it as it looked in the universe's early formative years, only 3 billion years after the Big Bang.
