In 2018, the James Webb Space Telescope is scheduled to launch. The Webb is a massive, space- based infrared observatory, an unprecedented savant in the search for stretched light. Its infrared sensors will be sensitive enough to measure the chemical properties of every object in the Ultra Deep Field – even the red dots.

“Our knowledge of this deep core of the Universe is about to get extremely detailed,” Stiavelli told me. The Webb will also see more ancient objects, galaxies too old and faint to be picked up by the Hubble. Its Ultra Deep Field could be freckled with red dots, and may well reach back to the cosmic dark ages.
