Research done by the Atacama Cosmology Telescope (ACT) project produced the clearest and most accurate images of the universe ...

A never-before-seen image of the cosmic microwave background, combining data from the Atacama Cosmology Telescope (ACT) and the Planck satellite, offers a high-definition view of the early Universe.

The polarization of light from the cosmic microwave background is key to understanding the young Universe. Sigurd Naess points out that ACT has five times higher resolution than Planck.
