Capturing the ‘Picture of the Big Bang’!

  • Friday, December 18th, 2015

“Astronomers said on Thursday they had discovered a galaxy that formed just 400 million years after the Big Bang explosion, the most distant galaxy found to date.

Located a record 13.4 billion light-years from Earth in the direction of the constellation Ursa Major, the galaxy, named GN-z11, was first spotted two years ago in a Hubble Space Telescope deep-sky visible light survey.

At the time, astronomers knew they were seeing something very far away, possibly as distant as 13.2 billion light-years from Earth.

Follow-up observations with an instrument on Hubble that splits light into its component wavelengths revealed that GN-z11 was farther away than initially believed, setting back the galaxy-formation clock by another 200 million years.

Being able to use Hubble to peg the galaxy’s distance was a surprise, said astronomers who will publish their research in next week’s issue of The Astrophysical Journal.”
