The oldest galaxy which scientists named as UDFj-39546284, was discovered using a Hubble telescope, according to National Aeronautics and Space Administration (NASA) on Wednesday, January 26, 2011. The galaxy is believed to be 13.2 billion light years away.

The details would be more specific when NASA’s James Webb Space telescope would finally spring into action. In the meantime, the scientists measured the age of the galaxy using a redshift. The redshift size will indicate the distance. When the redshift is bigger, the distance is longer. For the oldest galaxy, UDFj-39546284, it is at 10.3 which is equivalent to 13.2 billion light years.

Professor Garth Illingworth, its discoverer, said:

“It’s a time machine. We’re going back to seeing our own universe as it was when it was young.”
