Researchers created a technique to reduce uncertainty in cosmic birefringence measurements, resolving a key phase ambiguity and improving future studies of fundamental physics.

The cosmic microwave background (CMB) radiation is described as an imperceptible universal glow, representing the 13.8-billion-year-old remnant signature of the cosmos's primordial hot, dense origin.

Two scientists, Arno Penzias and Robert Wilson, discovered the cosmic microwave background in the mid-1960s while testing a large radio antenna for Bell Laboratories. They detected a constant signal ...

The most detailed snapshots so far of the infant universe are confirming that the cosmos consists mostly of mystery material, called dark energy, that accelerates the universe’s expansion. The new ...
