Scientists discover most distant galaxy in Universe

In a breakthrough, astronomers have discovered the most distant galaxy ever seen in the universe. By combining the power of NASA’s Hubble and Spitzer space telescopes and one of nature’s own natural “zoom lenses” in space, astronomers have discovered the farthest galaxy, which appears as a diminutive blob that is only a tiny fraction of the size of our Milky Way galaxy. Along the way, 8 billion years into its journey, light from MACS0647—JD took a detour along multiple paths around the massive galaxy cluster MACS J0647+7015. The cluster’s gravity boosted the light from the faraway galaxy, making the images appear about eight, seven, and two times brighter than they otherwise would that enabled astronomers to detect the galaxy more efficiently and with greater confidence. Based on observations of somewhat closer galaxies, astronomers estimate that a typical galaxy of a similar age should be about 2,000 light—years wide.
