Hubble takes never-seen-before space pics

NASA's Hubble space telescope has observed some of the oldest galaxies in the universe and has captured infrared images of them.

Hubble's newly installed wide field camera spotted several thousand never-before-seen galaxies. The newly observed galaxies were formed 600 million years after the Big Bang.

Big Bang is the name of the massive cosmic explosion that is hypothesized to have led to the creation of the universe.

The highly sensitive Wide Field Camera 3 monitored galaxies about 13 billion light years away. Each light year is more than 9 trillion kilometers.

"Hubble has now revisited the Ultra Deep Field which we first studied five years ago, taking infrared images which are more sensitive than anything obtained before," said Daniel Stark, a postdoctoral researcher at the Institute of Astronomy in Cambridge who was involved in the work.

The camera is sensitive to infrared light, which has wavelengths about twice as long as visible light and cannot be detected by the human eye.
