The cosmic microwave background (CMB) is the relic radiation from the early Universe, imprinted at the epoch of recombination when photons decoupled from matter. Detailed measurements of its ...

The cosmic microwave background (CMB) carries an imprint of the early Universe in its temperature and polarisation patterns. Standard cosmological models predict that Thomson scattering at ...

One of the Holy Grails in cosmology is a look back at the earliest epochs of cosmic history. Unfortunately, the universe's first few hundred thousand years are shrouded in an impenetrable fog. So far, ...

As it studies cosmic microwaves, the Simons Observatory in Chile aims to help prove or disprove cosmic inflation, a notion that the universe expanded rapidly in the moment after the Big Bang. Two of ...

Future missions will be able to find signatures of violating the parity-symmetry in the cosmic microwave background polarization more accurately after a pair of researchers has managed to take into ...

"Studying the relic radiation from the beginning of the universe is critical for understanding how the entire cosmos came to be and why it is the way it is." When you purchase through links on our ...

Roughly 400,000 years after the Big Bang, the universe cooled just enough to allow photons to escape from the primordial cosmological soup. Over the next 14 billion years, these ancient photons—the ...

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 ...
