A new image of cosmic microwave background radiation (half-sky image at left, closeup at right) adds high definition from the Atacama Cosmology Telescope to an earlier image from the Planck satellite.

Research by the Atacama Cosmology Telescope collaboration has led to the clearest and most precise images yet of the universe’s infancy, the cosmic microwave background radiation that was visible only ...
