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

The standard model of cosmology relies on an accurate reading of the cosmic microwave background. This radiation, emitted 380,000 years after the Big Bang, is considered proof of the theory's validity ...

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

A ground telescope in Chile detected cosmic polarization signals, confirming the universe’s first stars' timeline.

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

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.

There is something else that fills up the voids: radiation. The cosmic microwave background — the leftover light from when the universe was only 380,000 years old — soaks the entire cosmos ...

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 ...

Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark photons to be considered serious candidates for dark matter, with promising ...

A massive beach ball, a sky full of helium balloons, and one wild experiment. We asked the question no one dared: can we really make it fly? The answer is anything but ordinary.

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 ...
