Hubble telescope spots the oldest galaxies
"Astronomers have used the Hubble space telescope to discover the faintest and most distant galaxies ever seen. A new camera fitted to the orbiting observatory in May by shuttle astronauts has captured dim red "star cities" that formed only 600-900 million years after the Big Bang.The universe is thought to be around 14 billion years old and this new glimpse of them is a look back in time more than 13 billion years. Two teams from the universities of Oxford and Edinburgh picked out the candidates for most remote galaxies in images taken in infrared light by Hubble's new Wide Field Camera 3".
