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

"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.

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

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.

Cosmic microwaves are mere millimeters in wavelength and very faint. The signal from polarized microwave light is about a million times fainter. On Earth, broadcast radio waves, radar, and ...

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 findings will help better define signals coming from the residual glow of the Big Bang, or the cosmic microwave background, and form a clearer picture of the early universe.

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

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 ...
