In a big scientific breakthrough, US astronomers have discovered the most distant Galaxy ever seen in the Universe. Using NASA’s Hubble and Spitzer telescopes and nature’s own natural “zoom lenses” in space, astronomers have discovered the farthest Galaxy, which appears as a small blob only a tiny fraction of our Milky Way Galaxy.



Because of gravitational lensing, the Cluster Lensing and Supernova Survey with Hubble (CLASH) research team could observe three magnified images of MACS0647-JD with the Hubble telescope.

Named MACS0647-JD, the Galaxy was observed 420 million years after the big bang, the theorised beginning of the universe. Its light has traveled 13.3 billion years to reach Earth. The Galaxy offers a look back into a time when the universe was 3 % of its present age of 13.7 billion years.



Based on observations of somewhat closer galaxies, scientists estimate that a typical galaxy of a similar age should be about 2,000 light-years wide.
