One of the Oldest Galaxies spotted by Spitzer and Hubble

NASA’s spacecrafts, Hubble and Spitzer have used nature’s own telescope, gravitational lenses to observe a galaxy that was probably formed only 650 million years after the Big Bang. This ancient galaxy is 30 times smaller than our own Milky Way but producing new stars 10 times faster. Hubble first spots the distant galaxies and then Spitzer confirms if they are as far away as they appear to be by measuring the infrared redshift.
