The Hubble Space Telescope recently took a picture showing amazing detail in galaxies at extreme distances.
From the Hubble Space Telescope Institute:
JUNE 3, 2014: Astronomers using the Hubble Space Telescope have assembled a comprehensive picture of the evolving universe — among the most colorful deep space images ever captured by the 24-year-old telescope. This study, which includes ultraviolet light, provides the missing link in star formation.
The image shows galaxies so far away that they are seen at a time just a few hundred million years after the big bang. The light from these galaxies took over 12 billion years to reach us.
The image is in ultraviolet light. UV light picks up young hot stars - stars visible not long after they were formed.
The further the galaxies that astronomers can image, the further back in time they can see, all the way back to just after the Big Bang.
