Two of NASA's Great Observatories, the Spitzer and Hubble Space Telescopes, have teamed up to "weigh" the stars in several distant galaxies. One of these galaxies, among the most distant ever seen, appears to be unusually massive and mature for its place in the young universe.
This came as a surprise to astronomers. The earliest galaxies in the universe are commonly thought to have been much smaller associations of stars that gradually merged to build large galaxies like our Milky Way.

"This galaxy, named HUDF-JD2, appears to have 'bulked up' amazingly quickly, within the first few hundred million years after the big bang. It made about eight times more mass in stars than are found in our own Milky Way today, and then, just as suddenly, it stopped forming new stars," said Dr. Bahram Mobasher of the Space Telescope Science Institute, Baltimore, and the European Space Agency, Paris.
