In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe ...

Is it possible to understand the Universe without understanding the largest structures that reside in it? In principle, not ...

"Using the new common signal, we can determine how much of what we're seeing is cosmic glare from light bouncing off the hood of the Cosmic Dawn, so to speak." ...

The CLASS telescope array has taken a fresh look at the infant universe to hunt for polarized light in the Cosmic Microwave Background that resembles light bouncing off a cosmic car hood.

It is illuminated by the dense cosmic microwave background (CMB) radiation of the early universe and provides unprecedented insights into black hole behaviour and galactic development during the ...

The South Pole Telescope has mapped our skies in more detail than ever before, strengthening our understanding of dark energy ...

New observations support the idea that hot, diffuse threads of gas called cosmic filaments connect clusters of galaxies ...

Another clue about the whereabouts of the missing matter in the Universe has just emerged from amid the largest local cosmic structure. X-ray observations have revealed a massive filament of hot gas, ...

The black hole is located 11.6 billion light-years from Earth when the cosmic microwave background (CMB), the leftover glow from the Big Bang, was much denser than it is now.

For the first time, astronomers have used a ground-based telescope to observe polarized microwave light from the universe's earliest epoch. Their observations could give them a better understanding of ...
