• Scientists have described evidence for a galaxy called EGS8p7 that is more than 13.2 billion years old. The universe itself is about 13.8 billion years old. By this definition, EGS8p7 is now considered the farthest and the oldest galaxy.
  • They detected it using the MOSFIRE spectrometer, which captures the chemical signatures of everything from stars to the distant galaxies at near-infrared wavelengths (0.97-2.45 microns, or millionths of a meter).
  • EGS8p7 may have been populated by exceptionally hot stars that created a giant hydrogen bubble and broadcast the galaxy's presence. Whatever factors led to this rare sighting, it's clear that humanity's understanding of the oldest galaxies still needs some fine-tuning.
