Scientists studying a mysterious effect called cosmic birefringence—a subtle twist in the polarization of the universe’s oldest light—have developed a new way to reduce uncertainty in how it’s ...

Scientists are reeling from an unexpected blow after news that a much anticipated future observatory—designed to decipher the earliest moments of cosmic history—won’t be able to proceed with its ...

Cosmic microwave background is the oldest light in the universe. Cosmic microwave background is the oldest light in the universe. It was set free when the universe was a mere 380,000 years old and ...

The earliest light in the universe has been traveling across space since just after the Big Bang. Known as the cosmic microwave background, it is imperceptible to the human eye. But if scientists can ...

Arecibo Observatory observations of galactic neutral hydrogen structure confirm the discovery of an unexpected contribution to the measurements of the cosmic microwave background observed by the WMAP ...

For decades, astronomers were certain that half of the ordinary matter in the universe — protons and neutrons, the building blocks of everything we see — had simply gone unaccounted for. The cosmic ...

The events surrounding the Big Bang were so cataclysmic that they left an indelible imprint on the fabric of the cosmos. We can detect these scars today by observing the oldest light in the universe.

New research has unveiled images of the universe in its infancy—a mere 388,000 after the Big Bang. The snaps of the universe were produced by the Atacama Cosmology Telescope collaboration (ACT), which ...

Our knowledge of dark matter remains shrouded with darkness. Projections based on the glow of nearby galaxies have led to the small amount of what we know about dark matter. However, the starlight ...
