NASA's Hubble and Spitzer Space Telescopes are providing a new perspective on the remote universe, including new views of young and distant galaxies bursting with stars. Scientists described the findings Tuesday in a news conference sponsored by the American Astronomical Society.

The discoveries include four unusually bright galaxies as they appeared 13 billion years ago and the deepest image ever obtained of a galaxy cluster.

The ultra-bright, young galaxies, discovered using data from Hubble and Spitzer, are bursting with star-formation activity, which accounts for their brilliance. The brightest one is forming stars approximately 50 times faster than our Milky Way galaxy does today. These fledgling galaxies are only one-twentieth the size of the Milky Way, but they probably contain about 1 billion stars crammed together.

Although Hubble has previously identified galaxies at this early epoch, astronomers were surprised to find objects that are about 10 to 20 times more luminous than anything seen previously.

are why we are here today. They are the furnace generating the heavier elements that make us.

Deepest galaxy cluster ever pictured by Hubble

By James Morgan
Science reporter, BBC News, Washington DC

The "deepest ever" image of a group of galaxies - "Pandora's Cluster" - has been captured by the Hubble Space Telescope.

The blue arcs in the picture are distant galaxies as they appeared 12 billion years ago - not long after the Big Bang.

The hidden objects are revealed through the "magnifying lens" of the cluster Abell 2744.

The image was unveiled at the 223rd meeting of the American Astronomical Society (AAS) in Washington DC.
