These cosmic filaments contain 12 trillion solar masses of 10-million-degree gas, helping solve the "missing matter" mystery.

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 years, scientists have worked to chart the universe’s massive structure, aiming to test key models of cosmology. These ...

The James Webb Space Telescope is only three years into operations, yet it keeps slipping the cosmic rug out from under ...

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 ...

Seen as a long strand with smaller threads branching, the Quipu superstructure contains 68 galaxy clusters spanning 1.4 ...

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.

Besides enabling it to map 75% of the night sky ... not only enabled microwave-wavelength light to move freely — filling space with the cosmic microwave background (CMB) — but also, where it was dense ...
