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 ...

Finally, the new maps from QUIJOTE have permitted the systematic study of over 700 sources of emission in radio and microwaves, of both Galactic and extragalactic origin, meaning that the data is ...

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 ...

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 ...

A new study, published on Arxiv, has deepened the cosmic puzzle surrounding the “Hubble tension,” an ongoing debate about the universe’s expansion rate. The findings come from the Atacama Cosmology ...

Add Yahoo as a preferred source to see more of our stories on Google. A new map of the sky, made with observations from the Atacama Cosmology Telescope, showing dark matter. The orange regions show ...

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 ...

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 ...

Some of the largest and most sophisticated telescopes ever made are under construction at the Simons Observatory in Northern Chile. They are designed to measure cosmic microwave ...
