<p>This composite of Hubble images shows several ultra-bright young galaxies from 13 billion years ago. The four circled red objects--which appear red because their light has been stretched to longer infrared wavelengths by the expansion of the universe--are captured as they would have appeared a mere 500 million years after the Big Bang. These bright young galaxies are only one-twentieth the size of our own galaxy the Milky Way, but the brightest one is forming stars approximately 50 times faster.</p>
