NASA images galaxy from time when universe was 4% of its age
NASA has imaged one of the farthest galaxies, which existed when the universe was 500 million years old, about 3.6% of its current age. Light from distant galaxies takes time to reach Earth, allowing astronomers to look into the universe's history. Astronomers combined Hubble and Spitzer space telescopes' data obtained via "gravitational lensing", predicted by Albert Einstein a century ago.
