The cosmic microwave background (CMB) provides a snapshot of the infant Universe, offering critical insight into fundamental cosmological parameters, the physics of inflation and the distribution of ...

Nearly 400,000 years after the Big Bang, the primordial plasma of the infant universe cooled enough for the first atoms to coalesce, making space for the embedded radiation to soar free. That ...

So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and helium, and fluctuations of energy and matter set into motion the formation of ...

Our latest and best ever map of the early universe is five times more detailed than anything we have had before, but while it precisely backs up the leading model of the universe, it is also a ...

With CMB-S4, scientists hope to connect a sandy desert with a polar desert—and revolutionize our understanding of the early universe. In the 1960s, an anomalous, faint electromagnetic glow was ...

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 ...

Cosmologists are using secondary signatures from the cosmic microwave background to map the universe’s hidden matter. Nearly 400,000 years after the Big Bang, the primordial plasma of the infant ...

For decades, astronomers have known that galaxies are not scattered randomly through space. They cling to an enormous, mostly ...

For the first time, scientists have used Earth-based telescopes to look back over 13 billion years to see how the first stars in the universe affect light emitted from the big bang. Using telescopes ...
