Spotting them requires telescopes sensitive enough to detect faint, low-mass galaxies at extreme distances, and precise enough to confirm that the galaxies are truly bound together.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang.
