Astronomers have unveiled the view of the universe's youngest galaxies, offering the earliest look yet at the youngest galaxies of our own Milky Way. The objects were cited in pictures taken by the Hubble Space Telescope's Wide Field Camera 3, a new camera installed in 2009.

The images combined the data from the Spitzer Space Telescope, show that the newfound galaxies are relatively small, and they appear ultra blue, a color citing the presence lighter elements such as hydrogen and helium, causing galaxies to glow in a rainbow of colors. So the extreme blueness of the newfound galaxies suggests that they formed before very many massive stars had lived and died.

"We're just at the beginning of this story", says former astronaut John Grunsfeld, who led the team that repaired the space telescope last year and now is the deputy chief of Livio's institute. "It's incredibly thrilling to see these new instruments working and delivering results."

These galaxies are believed to form around 500 million years after the big bang, which took place around 13.7 billion years ago.
