New insights from the Atacama Cosmology Telescope offer unprecedented images of the universe at 380,000 years old, revealing movements and polarization of cosmic light with exceptional clarity. These

New research by the Atacama Cosmology Telescope (ACT) collaboration has produced the clearest images yet of the universe's infancy—the earliest cosmic time yet accessible to humans. Measuring light that traveled for more than 13 billion years to reach a telescope high in the Chilean Andes,

For the first time, scientists have captured the clearest and most detailed image of the cosmic microwave background (CMB)—the faint glow of the Big Bang, dating back 380,000 years after the universe was born.
